2,2′-(Disulfanedi­yl)dibenzoic acid–2,9-dimethyl­phenanthroline–tetra­hydro­furan (1/2/1)

Abstract

The asymmetric unit of the title co-crystal solvate, C₁₄H₁₀O₄S₂·2C₁₄H₁₂N₂·C₄H₈O, comprises a 2,2′-(disulfanedi­yl)dibenzoic acid mol­ecule, two mol­ecules of 2,9-dimethyl­phenanthroline and a tetra­hydro­furan (THF) solvent mol­ecule. Each end of the twisted diacid [dihedral angle between the benzene rings = 74.33 (17)°] forms a strong O—H⋯N hydrogen bond with a 2,9-dimethyl­phenanthroline mol­ecule, forming a trimeric aggregate. The crystal structure comprises layers of acid and THF mol­ecules, and layers of 2,9-dimethyl­phenanthroline mol­ecules that alternate along the a axis, the main connections between them being of the type C—H⋯O.

Comment

As a continuation of studies into the phenomenon of co-crystallization of 2-[(2-carboxyphenyl)disulfanyl]benzoic acid (Broker & Tiekink, 2007; Broker et al., 2008; Broker & Tiekink, 2010; Arman et al., 2010), the co-crystallization of this dithiodibenzoic acid and 2,9-dimethylphenanthroline was investigated. This lead to the isolation of the title co-crystal Tetrahydrofuran (thf) solvate.

The crystallographic asymmetric unit of the title compound comprises one molecule of dithiodibenzoic acid (Fig. 1), two molecules of 2,9-dimethylphenanthroline (Figs. 2 and 3), and a solvent thf molecule. The acid adopts the expected conformation (Broker & Tiekink, 2007), stabilized in part by two close S···O(carbonyl) interactions, i.e. S1···O1 = 2.713 (3) Å and S2···O3 = 2.711 (3) Å; the dihedral angle formed between the benzene rings = 74.33 (17) °. Each carboxylic acid-H forms a close hydrogen bond to a phenanthroline-N (Table 1), and in the case of the N1-phenanthroline molecule, a weaker O2—H···N2 interaction is noted; the equivalent O4—H···N4 contact is longer than 2.66 Å. These interactions result in the formation of a trimeric aggregate, Fig. 4.

In the crystal packing the dithiodibenzoic acid and tetrahydrofuran molecules assemble into layers in the bc plane interspersed by layers of 2,9-dimethylphenanthroline molecules, with the most prominent interactions between them being of the type C—H···O (see Fig. 5 and Table 1).

Experimental

Gold coloured crystals of the title compound were obtained by the co-crystallization of 2-[(2-carboxyphenyl)disulfanyl]benzoic acid (Fluka, 0.02 mmol) and 2,9-dimethylphenanthroline (ACROS, 0.02 mmol) in tetrahydrofuran. Crystals were obtained by slow evaporation.

Refinement

The O-bound H-atoms were located in a difference Fourier map and were refined with a distance restraint of O–H 0.84 (1) Å, and with U_iso(H) = 1.5U_eq(O). C-bound H-atoms were placed in calculated positions and were included in the refinement in the riding model approximation: C–H 0.95, 0.99 and 0.98 Å for CH, CH₂ and CH₃ H-atoms, respectively, with U_iso(H) = k × U_eq(C), where k = 1.5 for CH₃ H-atoms and 1.2 for all other H-atoms. High thermal motion was associated with the tetrahydrofuran molecule but an alternate conformation could not be resolved. The constituent atoms were refined isotropically with O—C and C—C distance restraints of 1.43 (1) and 1.50 (1) Å, respectively. In the final refinement a low angle reflection evidently effected by the beam stop was omitted, i.e. (101).

Special details

Geometry. All s.u.'s (except the s.u. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell s.u.'s are taken into account individually in the estimation of s.u.'s in distances, angles and torsion angles; correlations between s.u.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell s.u.'s is used for estimating s.u.'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 > 2σ(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.
