The CoII atom in the crystal structure of diaquabis(N,N-diethylnicotinamide)bis(2,4,6-trimethylbenzoato)cobalt(II) is located on an inversion centre and exhibits a slightly distorted octahedral N2O4 coordination set. Hydrogen bonds of the type O—H⋯O and C—H⋯O lead to the formation of a three-dimensional network.

Abstract
The centrosymmetric molecule in the monomeric title cobalt complex, [Co(C10H11O2)2(C10H14N2O)2(H2O)2], contains two water molecules, two 2,4,6-trimethylbenzoate (TMB) ligands and two diethylnicotinamide (DENA) ligands. All ligands coordinate to the CoII atom in a monodentate fashion. The four O atoms around the CoII atom form a slightly distorted square-planar arrangement, with the distorted octahedral coordination sphere completed by two pyridine N atoms of the DENA ligands. The dihedral angle between the planar carboxylate group and the adjacent benzene ring is 84.2 (4)°, while the benzene and pyridine rings are oriented at a dihedral angle of 38.87 (10)°. The water molecules exhibit both intramolecular (to the non-coordinating carboxylate O atom) and intermolecular (to the amide carbonyl O atom) O—H⋯O hydrogen bonds. The latter lead to the formation of layers parallel to (100), enclosing R 4 4(32) ring motifs. These layers are further linked via weak C—H⋯O hydrogen bonds, resulting in a three-dimensional network. One of the two ethyl groups of the DENA ligand is disordered over two sets of sites with an occupancy ratio of 0.490 (13):0.510 (13).
Chemical context
N,N-Diethylnicotinamide (DENA), a nicotinic acid derivative, is an important respiratory stimulant (Bigoli et al., 1972 ▸). The crystal structure of the complex [Co(CH3CO2)2(DENA)2(H2O)2] [(II); Mikelashvili, 1982 ▸] is isostructural with the analogous Ni, Mn, Zn and Cd complexes (Sergienko et al., 1980 ▸). The structures of some complexes obtained from the reactions of transition metal(II) ions with DENA as ligand, e.g. [Cu2(DENA)2(C6H5COO)4] [(III); Hökelek et al., 1995 ▸], [Zn2(C7H5O3)4(DENA)2]·2H2O [(IV); Hökelek & Necefoğlu, 1996 ▸], [Mn(DENA)2(NCS)2] [(V); Bigoli et al., 1973a ▸], [Zn(DENA)2(NCS)2(H2O)2] [(VI); Bigoli et al., 1973b ▸] and [Cd(DENA)(SCN)2] [(VII); Bigoli et al., 1972 ▸], have been determined previously. In complex (V), DENA is a bidentate ligand, while in complexes (III), (IV), (VI) and (VII), DENA is a monodentate ligand. In complex (III), the benzoate ion acts as a bidentate ligand, whereas in complex (IV), two of the benzoate ions act as monodentate ligands, while the other two are bidentate, bridging the two ZnII atoms.
The structure–function–coordination relationships of arylcarboxylate ions in CoII complexes of benzoic acid derivatives may change depending on the nature and position of the substituted groups on the benzene ring, the nature of the additional ligand molecule or solvent, and the pH conditions and temperature of synthesis (Shnulin et al., 1981 ▸; Nadzhafov et al., 1981 ▸; Antsyshkina et al., 1980 ▸; Adiwidjaja et al., 1978 ▸). When pyridine or its derivatives are used instead of water molecules, the resulting structure is completely different (Catterick et al., 1974 ▸). In this context, we synthesized a CoII-containing compound with 2,4,6-trimethylbenzoate (TMB) and DENA ligands, namely diaquabis(N,N-diethylnicotinamide-κN
1)bis(2,4,6-trimethylbenzoato-κO
1)cobalt(II), [Co(DENA)2(TMB)2(H2O)2], and report herein its crystal structure.
Structural commentary
The asymmetric unit of the mononuclear title complex contains one CoII atom located on an inversion centre, one TMB ligand, one DENA ligand and one water molecule, with all ligands coordinating to the metal ion in a monodentate fashion (Fig. 1 ▸).

The molecular structure of the title complex with the atom-numbering scheme for the asymmetric unit. Unlabelled atoms are generated by symmetry code (1 − x, 1 − y, −z). Displacement ellipsoids are drawn at the 40% probability level. Intramolecular O—H⋯O hydrogen bonds are shown as dashed lines.
The two carboxylate O atoms (O2 and O2i) of the two symmetry-related TMB anions and the two symmetry-related water O atoms (O4 and O4i) form a slightly distorted square-planar arrangement around the Co1 atom. The slightly distorted octahedral coordination sphere is completed by the two pyridine N atoms (N1 and N1i) of the two symmetry-related DENA ligands in axial positions [symmetry code: (i) 1 − x, 1 − y, −z] (Fig. 1 ▸). The Co—O bond lengths for water oxygens atoms are by ca 0.1 Å longer than those involving the benzoate oxygen atoms. The Co—N bond length is the longest in the CoO4N2 octahedron (Table 1 ▸). The deviation of the O—Co—O and O—Co—N bond angles from ideal values is minute [range 87.66 (7) to 92.34 (7)° for cis angles; all trans angles are 180° due to symmetry]. The near equalities of the C1—O1 [1.245 (4) Å] and C1—O2 [1.254 (4) Å] bonds in the carboxylate group indicate delocalized bonding arrangements, rather than localized single and double bonds. The dihedral angle between the planar carboxylate group (O1/O2/C1) and the adjacent benzene ring A (C2–C7) is 84.2 (4)°, while the benzene (A) and pyridine rings (B) (N1/C11–C15) are inclined by a dihedral angle of 38.87 (10)°.

Supramolecular features
Intramolecular O—Hw⋯Oc (w = water, c = non-coordinating carboxylate O atom) hydrogen bonds (Table 2 ▸) link the water ligands to the TMB anions (Fig. 1 ▸). The other water H atom is involved in intermolecular O—Hw⋯ODENA (ODENA = carbonyl O atom of N,N-diethylnicotinamide) hydrogen bonds (Table 2 ▸), leading to the formation of layers parallel to (100) enclosing 
(32) ring motifs (Fig. 2 ▸). The layers are further linked into a three-dimensional network structure via weak C—HTMB⋯Oc (TMB = 2,4,6-trimethylbenzoate) and C—HDENA ⋯ ODENA hydrogen bonds (Table 2 ▸), enclosing 
(7) ring motifs (Fig. 3 ▸).

Only one part of the disordered group and only H atoms involved in hydrogen bonding have been included for clarity.
Synthesis and crystallization
The title compound was prepared by the reaction of CoSO4·7H2O (1.41 g, 5 mmol) in H2O (100 ml) and N,N-diethylnicotinamide (1.78 g, 10 mmol) in H2O (10 ml) with sodium 2,4,6-trimethylbenzoate (1.86 g, 10 mmol) in H2O (150 ml). The mixture was filtered and set aside to crystallize at ambient temperature for three weeks, giving pink single crystals.
Refinement
Experimental details including crystal data, data collection and refinement are summarized in Table 3 ▸. Atoms H1W and H2W (of the water molecule) were located in a difference Fourier map. Their coordinates were refined freely, with U iso(H) = 1.5U eq(O). C-bound H atoms were positioned geometrically, with C—H = 0.93, 0.96 and 0.97 Å for aromatic, methyl and methylene H atoms, respectively, and constrained to ride on their parent atoms, with U iso(H) = k × U eq(C), where k = 1.5 for methyl H atoms and k = 1.2 for other H atoms. The disordered ethyl group (C19, C20) was refined over two sets of sites with distance restraints and SIMU and DELU restraints (Sheldrick, 2008 ▸). The refined occupancy ratio of the two orientations is 0.490 (13):0.510 (13).

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