Crystal structure of bis-p-anizidinegossypol with an unknown solvate

In the solid-state, bis-p-anizidinegossypol exists in the enamine or quinoid form. The naphthyl moieties are close to perpendicular [dihedral angle = 72.08 (5)°]. In the crystal, mol­ecules are linked by O—H⋯O hydrogen bonds, generating layers which surround channels occupied by disordered guest mol­ecules.

Abstract

The title compound, C₄₄H₄₄N₂O₈, (systematic name: 1,1′,6,6′-tetra­hydroxy-5,5′-diisopropyl-8,8′-bis­{[(4-meth­oxy­phen­yl)iminium­yl]meth­yl}-3,3′-dimethyl-2,2′-bi­naphthalene-7,7′-diolate) has been obtained by the addition of p-anizidine to gossypol dissolved in di­chloro­methane. In the solid state, the title compound exists in the enamine or quinoid form. The two naphthyl moieties are inclined to one another by 72.08 (5)°. The pendant phenyl rings are inclined at 22.26 (14) and 23.86 (13)° to the corresponding naphthyl rings. In the crystal, mol­ecules are incorporated into layers through inversion-related pairs of O—H⋯O inter­actions [graph sets R ₂ ²(20) and R ₂ ²(10)] and translation-related O—H⋯O inter­actions [graph set C(15)]. The packing of these layers in the crystal structure gives rise to channels in the [011] direction, with hydro­phobic inter­actions occurring between adjacent layers. The channels are 5–7 Å wide, and the void volume of each cell is 655 ų, corresponding to 26.6% of the cell volume. Disordered guest mol­ecules, probably solvent and water mol­ecules, occupy these voids of the crystal; their contribution to the scattering was removed with the SQUEEZE routine [Spek (2015 ▸). Acta Cryst. C71, 9–18] of PLATON [Spek (2009 ▸). Acta Cryst. D65, 148–155].

Chemical context  

Gossypol [2,2′-bis­(8-formyl-1,6,7-trihy­droxy-5-isopropyl-3-methyl­naphthalene)] is a yellow pigment of cotton seeds (Adams et al., 1960 ▸). This compound was first isolated over 110 years ago (Marchlewski, 1899 ▸). Its study was initially important because the compound is associated with anti-nutritive or even toxic effects when cottonseed is overfed to animals. Many attempts have been made to either remove it from cottonseed or reduce its toxicity (Kenar, 2006 ▸). However, the compound also has a wide range of biological action, including anti-HIV (Jian Yang et al., 2014 ▸), anti­cancer (Zhan et al., 2009 ▸) and anti­fertility (Coutinho, 2002 ▸) effects. This inter­est has led to the synthesis and isolation of various gossypol derivatives, including many di­amine-based gossypol Schiff bases. Gossypol and its Schiff base formed with aniline have been previously reported to form inclusion compounds with many small organic compounds (Beketov et al., 1994 ▸; Gdaniec et al., 1996 ▸; Talipov et al., 2004 ▸). Some gossypol polymorphs (referred to as the P3 polymorph; Ibragimov et al., 1994 ▸), dianhydro­gossypol (Talipov et al., 2009 ▸) and gossypol tetra­methyl ether (Honkeldieva et al., 2015 ▸) form open-channel structures with channels of 5–8 Å width. In this report, we demonstrate that the Schiff base of gossypol with p-anizidine also forms an open-channel structure when the compound is crystallized from solutions in di­chloro­methane.

Structural commentary  

Gossypol can exist in one of the following tautomeric forms: aldehyde, quinoid and lactol (Adams et al., 1960 ▸). In most solvents it is found in the aldehyde form; however, there are some reports that gossypol also exists in a pure lactol form (Reyes et al., 1986 ▸) or as a dynamic equilibrium mixture of aldehyde and lactol forms in some highly polar solvents (Kamaev et al., 1979 ▸). In the structure described here, the title compound is in the enamine or quinoid form. The highest symmetry which the title compound mol­ecule can possess is C ₂ (twofold axis perpendicular to the C2—C12 bond). However, bis-p-anizidinegossypol crystallizes in a triclinic (P ) space group and the symmetry of the mol­ecule is not retained in the crystal. An ORTEP diagram of the mol­ecule and the atom numbering in the structure are given in Fig. 1 ▸.

Figure 1.

The mol­ecule consists of four ring systems, two of which are naphthalene ring systems, and the other two are phenyl rings. The C1–C10 naphthyl unit is more planar then C11–C20 naphthyl one in which atoms C12, C16, C17, C18 and C19 deviate by 0.051 (3), 0.070 (3), 0.059 (3), 0.082 (3) and 0.054 (3) Å, respectively, from the mean plane. The two naphthyl moieties are inclined to one another by 72.08 (5)°. The phenyl rings are inclined at 22.26 (14) and 23.86 (13)° to the corresponding naphthyl rings. The bond lengths and angles are mostly in good agreement with those observed in the analogous fragments of the gossypol and dianilinegossypol mol­ecules (Gdaniec et al., 1996 ▸; Talipov et al., 2004 ▸). However, there are notable differences in the lengths of some bonds compared with typical gossypol values. Compared with the relatively short C6—C7 (C16—C17) aromatic ring bonds of gossypol mol­ecules (1.40 Å), the corresponding bonds in the bis-p-anizidinegossypol mol­ecule are longer with lengths of 1.446 (4) and 1.476 (4) Å. In addition, the N1—C22 [1.332 (4) Å] and N2—C27 [1.319 (4) Å] bonds are shorter than N1—C31 [1.433 (4) Å] and N2—C38 [1.441 (4) Å], respectively. Contrarily, C7=O3 [1.289 (3) Å] and C17=O7 [1.275 (3) Å] bonds are longer than typical standard values.

There are two intra­molecular hydrogen bonds in the mol­ecule. The N1—H1A⋯O3 (and N2—H2⋯O7) bond closes a six-membered ring C7—C8—C22—N1—H1A⋯O3 (and C17—C18—C27—N2—H3⋯O7), while the other type of hydrogen bond O4—H4⋯O3 (and O8—H8⋯O7) forms a five-membered ring C6—C7—O3⋯H4—O4 (and C16—C17—O7⋯H8—O8) (Table 1 ▸).

Supra­molecular features  

The packing of the title mol­ecules in the crystal is shown in Fig. 2 ▸. Bis-p-anizidinegossypol mol­ecules are incorporated into centrosymmetric dimers typical for gossypol and dianilinogossypol crystal structures by means of a pair of inversion-related hydrogen bonds O5—H5⋯O3 [graph set (20)]. By further centrosymmetric O8—H8⋯O7 hydrogen bonds [graph set (10)], mol­ecules are associated into columns running in the [1 ] direction, as also seen for the dianilinegossypol clathrate with ethyl­acetate (Beketov et al., 1994 ▸). A layer parallel to (01) is formed by linking of the columns via translation-related hydrogen bonds O1—H1⋯O6 [graph set (15)] in the [100] direction. The layer features a O2⋯C7(−1 − x, 1 − y, 1 − z) contact [3.254 (4) Å] and a very weak aromatic π–π stacking inter­action with a Cg⋯Cg(−1 − x, 1 − y, 1 − z) distance of 4.182 (2) Å where Cg is the centroid of the C31–C36 ring. The packing of these layers in the crystal structure gives rise to wide ragged channels in the [011] direction. The stabilization of the crystal structure is supported by hydro­phobic inter­actions between adjacent layers. The channels in the structure are 5-7 Å wide and the void volume of each cell is 655 ų, corresponding to 26.6% of the cell volume. Disordered solvated mol­ecules, probably solvent and water mol­ecules, occupy these voids of the crystal; their contribution to the scattering was removed with the SQUEEZE routine (Spek, 2015 ▸) of PLATON (Spek, 2009 ▸).

Database survey  

A search in the Cambridge Structural Database (Version 5.36; Groom & Allen, 2014 ▸) indicated the presence of 198 entries for gossypol (137 entries) or gossypol derivatives. The 35 entries of revealed 50 entries for Schiff-base gossypol deriv­atives are related to dianilinegossypol clathrates and polymorphs. The dihedral angle between the naphthalene ring systems in the dianilinegossypol structures is in the range 78 to 90°. The dihedral angles between naphthalene ring systems and the corresponding benzyl rings of aniline substituents are in the range 4–49°. The dihedral angles between the naphthalene ring systems in the crystal structures of other Schiff base gossypol derivatives are in the range from ca 70 to 90°: IGAVAQ = 86.6°, LUHBIA = 89.6°, LUHBOG = 77.9°, MEXROY = 89.2°, MEXROY01 = 88.9°, NOQFIJ = 83.5°, POGHUF = 84.6°, QADQIX = 89.1°, SACXEB = 82.2°, TEFFEP = 70.6° and 83.4°, TIJNUX = 89.0°, XATPAK = 78.6°, VUXRIQ = 70.3°, VUXRIQ01 = 88.2° and 91.0° and YORNIW = 81.2°.

Synthesis and crystallization  

Gossypol was obtained from the Experimental Plant of the Institute of Bioorganic Chemistry, Uzbekistan Academy of Sciences where it is produced from by-products of the cottonseed oil industry. To prepare the Schiff base complex, gossypol was mixed with p-anizidine in a 1:2 molar ratio in di­chloro­methane. This reaction solution was allowed to stand in the dark for some days, during which crystalline precipitates have been formed within the solution. The precipitate was recovered by filtration. Yield: 64%. After numerous attempts, a suitable crystal was selected from the precipitate and used for the diffraction study without additional recrystallization.

Refinement  

Crystal data, data collection and structure refinement details are summarized in Table 2 ▸. The H atom of the hy­droxy substituent was located in an electron density map and its coordinates were freely refined with U _iso = 1.5U _eq(O). C-bound H atoms were positioned geometrically and refined using a riding model, with d(C—H) = 0.93 Å and U _iso = 1.2U _eq(C) for aromatic, d(C—H) = 0.98 Å and Uiso = 1.2U _eq (C) for methine, d(C—H) = 0.96 Å and U _iso = 1.5U _eq (C) for methyl H atoms.

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes.

Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger.
