In the title complex, [Zn(C8H5O3)2(C10H14N2O)2(H2O)2], the ZnII cation is located on an inversion center and is coordinated by two 4-formyl­benzoate anions, two N,N-diethyl­nicotinamide (DENA) ligands and two water mol­ecules. The four O atoms in the equatorial plane around the ZnII cation form a slightly distorted square-planar arrangement, while the slightly distorted octa­hedral coordination is completed by the two N atoms of the DENA ligands in the axial positions. The dihedral angle between the carboxyl­ate group and the adjacent benzene ring is 2.96 (11)°, while the pyridine ring and the benzene ring are oriented at a dihedral angle of 79.26 (4)°. The coordinating water mol­ecule links with the carboxyl­ate group via an intra­molecular O—H⋯O hydrogen bond. In the crystal, O—H⋯O and weak C—H⋯O hydrogen bonds link the mol­ecules into a three-dimensional supra­molecular network. A ππ contact between the parallel pyridine rings of adjacent mol­ecules may further stabilize the crystal structure [centroid–centroid distance = 3.5654 (8) Å].

As a part of our ongoing investigations of transition metal complexes of nicotinamide (NA), one form of niacin (Krishnamachari, 1974), and/or the nicotinic acid derivative N,N-diethylnicotinamide (DENA), an important respiratory stimulant (Bigoli et al., 1972), the title compound was synthesized and its crystal structure is reported herein.

In the title mononuclear complex, ZnII cation is located on an inversion center and is coordinated by two 4-formylbenzoate (FB) anions, two N,N-diethylnicotinamide (DENA) ligands and two water molecules, all ligands coordinating in a monodentate manner (Fig. 1). The crystal structures of similar complexes of CuII, CoII, NiII, MnII and ZnII ions, [Cu(C7H5O2)2(C10H14N2O)2] (Hökelek et al., 1996), [Cu(C7H4BrO2)2(C6H6N2O)2(H2O)2] (Necefoğlu, Özbek et al., 2011), [Co(C6H6N2O)2(C7H4NO4)2(H2O)2] (Hökelek & Necefoğlu, 1998), [Co(C9H9O2)2(C10H14N2O)2(H2O)2] (Necefoğlu, Maracı et al., 2011), [Co(C7H4IO2)2(C6H6N2O)2(H2O)2] (Aydın et al., 2012), [Ni(C7H4ClO2)2(C6H6N2O)2(H2O)2] (Hökelek et al., 2009a), [Ni(C5H5O3)2(C6H6N2O)2(H2O)2] (Sertçelik et al., 2012), [Mn(C9H10NO2)2(H2O)4].2H2O (Hökelek & Necefoğlu, 2007) and [Zn(C7H4BrO2)2(C6H6N2O)2(H2O)2] (Hökelek et al., 2009b) have also been reported. In the copper(II) complex mentioned above the two benzoate ions coordinate to the CuII atom as bidentate ligands, while in the other structures all the ligands coordinate in a monodentate manner.

In the title complex, the four symmetry related O atoms (O2, O2', O5 and O5') in the equatorial plane around the ZnII ion form a slightly distorted square-planar arrangement, while the slightly distorted octahedral coordination is completed by the two symmetry related N atoms of the DENA ligands (N1 and N1') in the axial positions. The near equalities of the C1—O1 [1.2533 (16) Å] and C1—O2 [1.2623 (16) Å] bonds in the carboxylate group indicate delocalized bonding arrangement, rather than localized single and double bonds. The Zn—O bond lengths are 2.1128 (9) Å (for benzoate oxygens) and 2.1289 (10) Å (for water oxygens), and the Cu—N bond length is 2.1452 (11) Å, close to standard values (Allen et al., 1987). The Zn atom is displaced out of the mean-plane of the carboxylate group (O1/C1/O2) by 0.8455 (1) Å. The dihedral angle between the planar carboxylate group and the adjacent benzene ring A (C2—C7) is 2.96 (11)°. The benzene A (C2—C7) and the pyridine B (N1/C9—C13) rings are oriented at a dihedral angle of A/B = 79.26 (4)°. The coordinating water molecule links with the carboxylate group via an O—H···O hydrogen bond (Table 1).

In the crystal, intermolecular O—H···O and weak C—H···O hydrogen bonds (Table 1) link the molecules into a three-dimensional supramolecular network, in which they may be effective in the stabilization of the structure. The ππ contact between the pyridine rings, Cg2—Cg2i [symmetry code: (i) 1 - x, 1 - y, -z, where Cg2 is the centroid of the ring B (N1/C9-C13)] may further stabilize the structure, with centroid-centroid distance of 3.5654 (8) Å].

Experimental top

The title compound was prepared by the reaction of ZnSO4.H2O (0.90 g, 5 mmol) in H2O (30 ml) and DENA (1.78 g, 10 mmol) in H2O (10 ml) with sodium 4-formylbenzoate (1.72 g, 10 mmol) in H2O (100 ml) at room temperature. The mixture was filtered and set aside to crystallize at ambient temperature for several days, giving colorless single crystals.

Refinement top

Atoms H8 (for CH) and H51 and H52 (for H2O) were located in a difference Fourier map and were refined freely. The C-bound H-atoms were positioned geometrically with C—H = 0.93, 0.97 and 0.96 Å, for aromatic, methylene and methyl H-atoms, respectively, and constrained to ride on their parent atoms, with Uiso(H) = k × Ueq(C), where k = 1.5 for methyl H-atoms and k = 1.2 for all other H-atoms.

Special details top

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.
