In the mononuclear title compound, [Ni(C8H7O3)2(C6H6N2O)2(H2O)2]·2H2O, the NiII ion is located on a crystallographic inversion center. The asymmetric unit further contains one 4-meth­oxy­benzoate anion, one nicotinamide (NA) ligand and one coordinated and one uncoordinated water mol­ecule; all ligands are monodentate. The four O atoms in the equatorial plane around the NiII ion form a slightly distorted square-planar arrangement, while the slightly distorted octa­hedral coordination is completed by the two pyridine N atoms of the NA ligands in the axial positions. The dihedral angle between the carboxyl­ate group and the attached benzene ring is 7.2 (1)°, while the pyridine and benzene rings are oriented at a dihedral angle of 72.80 (4)°. An intra­molecular O—H⋯O hydrogen bond links the uncoordinated water mol­ecule to one of the carboxyl­ate groups. In the crystal structure, inter­molecular O—H⋯O, N—H⋯O and C—H⋯O hydrogen bonds link the mol­ecules into a three-dimensional network.

As a part of our ongoing investigation on 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.

The title compound, (I), is a mononuclear complex, where the NiII ion is located on a crystallographic inversion center. The asymmetric unit contains one 4-methoxybenzoate (PMOB) anion, one nicotinamide (NA) ligand and one coordinated and one uncoordinated water molecules, all ligands are monodentate (Fig. 1). The crystal structures of some NA and/or DENA complexes of CuII, CoII, NiII, MnII and ZnII ions, [Cu(C7H5O2)2(C10H14N2O)2], (II) (Hökelek et al., 1996), [Co(C6H6N2O)2(C7H4NO4)2(H2O)2], (III) (Hökelek & Necefoğlu, 1998), [Ni(C7H4ClO2)2(C6H6N2O)2(H2O)2], (IV) (Hökelek et al., 2009a), [Ni(C8H7O2)2(C6H6N2O)2(H2O)2], (V) (Necefoğlu et al., 2010), [Mn(C7H4ClO2)2(C10H14N2O)2(H2O)2], (VI) (Hökelek et al., 2009b) and [Zn(C7H4BrO2)2(C6H6N2O)2(H2O)2], (VII) (Hökelek et al., 2009c) have also been reported. In (II), two benzoate ions are coordinated to the Cu atom as bidentate ligands, while in other structures all ligands being monodentate.

The four O atoms (O1, O5, and the symmetry-related atoms, O1', O5') in the equatorial plane around the NiII ion form a slightly distorted square-planar arrangement, while the slightly distorted octahedral coordination is completed by the two N atoms of the NA ligands (N1, N1') in the axial positions (Fig. 1). The near equality of the C1—O1 [1.2681 (15) Å] and C1—O2 [1.2644 (16) Å] bonds in the carboxylate group indicates a delocalized bonding arrangement, rather than localized single and double bonds. The average Ni—O bond length is 2.0633 (9) Å (Table 1), and the NiII ion is displaced out of the least-squares plane of the carboxylate group (O1/C1/O2) by 0.7794 (1) Å. The dihedral angle between the planar carboxylate group and the benzene ring A (C2—C7) is 7.2 (1)°, while that between rings A and B (N1/C9—C13) is 72.80 (4)°. An intramolecular O—H···O hydrogen bond (Table 2) links the uncoordinated water molecule to one of the carboxylate groups (Fig. 1).

In the crystal structure, intermolecular O—H···O, N—H···O and C—H···O hydrogen bonds (Table 2) link the molecules into a three-dimensional network.

Experimental top

The title compound was prepared by the reaction of NiSO4.6H2O (2.63 g, 10 mmol) in H2O (50 ml) and nicotinamide (2.44 g, 20 mmol) in H2O (50 ml) with sodium 4-methoybenzoate (3.48 g, 20 mmol) in H2O (100 ml). The mixture was filtered and set aside to crystallize at ambient temperature for one week, giving blue single crystals.

Refinement top

Atoms H21, H22 (for NH2) and H51, H52, H61, H62 (for H2O) were located in a difference Fourier map and refined isotropically. The remaining H atoms were positioned geometrically with C—H = 0.95 and 0.98 Å for aromatic and methyl H atoms and constrained to ride on their parent atoms, with Uiso(H) = xUeq(C), where x = 1.5 for methyl H and x = 1.2 for aromatic 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.
