In the title mononuclear complex, [Ni(C8H7O2)2(C5H5N)2(H2O)], the NiII atom is in a distorted octa­hedral arrangement, coordinated by three carboxylate O atoms from one bidentate 4-methyl­benzoate ligand and one monodentate 4-methyl­benzoate ligand, two N atoms from pyridine ligands, axially positioned, and a water mol­ecule. The equatorially positioned water mol­ecule and uncoordinated carb­oxylate O atom form an intra­molecular hydrogen bond. An inter­molecular O—H⋯O hydrogen bond between the coordinated water mol­ecule and carboxylate O atom of the 4-methyl­benzoate ligand forms infinite chains along the b axis. These chains are connected by C—H⋯π inter­actions.

Comment top

In the structural investigation of 4-methylbenzoate complexes, it has been found that the 4-methylbenzoic acid functions as a multidentate ligand [Song et al. (2007)] with versatile binding and coordination modes. In this paper, we report the crystal structure of the title compound, (I), a new Ni complex obtained by the reaction of 4-methylbenzoic acid, pyridine and nickel chloride in alkaline aqueous solution.

The NiII atom exhibits a disordered octahedral environment (Fig. 1, Table 1) defined by three carboxyl O atoms from one bidentate 4-methylbenzoate ligand and one monodentate 4-methylbenzoate ligand, two N atoms from two pyridine ligands and a water molecule. The intermolecular O—H···O hydrogen bond (Table 2, Fig. 2) between the coordinated water molecule and carboxy O atom of 4-methylbenzoate ligand generates a chain along the axis b. The intermolecular hydrogen bond C1—H1···O also involves water molecule [3.339 (3) %A, 145%]. An intramolecular hydrogen bond connects the coordinated water molecule and uncoordinated oxygen atom O4 (Table 2). C—H···π interactions connect hydrogen bonded chains: C3– H3···Cg (C12 C17, symmetry code: -2 - x, 1/2 + y, 2 - z) of 3.482 (2) %A; 132%, and C14– H14···Cg(C12 C17, symmetry code: 1 - x, -1/2 + y, 2 - z) of 3.603 (2) %A; 134%; C22– H22···Cg(C20 C25, symmetry code: 2 - x, -1/2 + y, 1 - z) of 3.504 (2) %A; 133%.

Experimental top

A mixture of nickel chloride (1 mmol), 4-methylbenzoic acid (1 mmol), pyridine(1 mmol), NaOH (1.5 mmol) and H2O (12 ml) were placed into a 23 ml Teflon reactor, which was heated to 433 K for three days and then cooled to room temperature at a rate of 10 K h-1. The crystals obtained were washed with water and dryed in air.

Refinement top

Carbon-bound H atoms were placed at calculated positions and were treated as riding on the parent C atoms with C—H = 0.93 Å for aromatic rings, C—H = 0.96 Å for methyl group, and with Uiso(H) = 1.2 Ueq(C). Water H atoms were tentatively located in difference Fourier maps and were refined with distance restraints of O–H = 0.82 Å and H···H = 1.29 Å, each within a standard deviation of 0.01 Å; and with Uiso(H) = 1.5 Ueq(O).

Special details top

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.
