There are one and a half independent mol­ecules in the asymmetric unit of the title compound, [Ni(C8H8NO)2], one of which is situated on an inversion center. In both mol­ecules, the NiII ion is coordinated by two O and two N atoms from two Schiff base ligands in an approximate square-planar geometry. Inter­molecular N—H⋯O hydrogen bonds link three mol­ecules into centrosymmetric trimer. The crystal packing exhibits weak inter­molecular C—H⋯O hydrogen bonds and voids of 37 Å3.

Comment top

The Schiff bases are a kind of versatile ligands used in coordination chemistry (Haikarainen et al., 2001; Miyasaka et al., 2002). The complexes derived from Schiff bases have proved to be of significant interest in the areas of catalysis, magnetism, medicinal and material chemistry. In the present paper, the title compound (I) - a new Schiff base nickel(II) complex - is reported.

The molecule of (I) is mononuclear nickel(II) complex. The asymmetric unit of (I) contains two crystallographically independent molecules, one of which is situated on inversion center. The Ni atom is coordinated by two O and two N atoms from two Schiff base ligands, forming a square planar geometry. The bond lengths related to the Ni atoms are comparable to those observed in other nickel(II) complexes with Schiff bases (Liu et al., 2006; Wang, 2010), but shorter than the Cu–N and Cu–O bonds observed in a structurally similar copper(II) complex (Marongiu & Lingafelter, 1971).

Intermolecular N—H···O hydrogen bonds link three molecules in (I) into centrosymmetric trimer (Fig. 1). The crystal packing exhibits weak intermolecular C—H···O hydrogen bonds and voids of 37 Å3.

Experimental top

To a stirred ethanolic solution (30 ml) of 2-acetylphenol (0.136 g, 1 mmol) was added a few drops of 30% ammonia and an ethanolic solution (20 ml) of nickel(II) nitrate hexahydrate (0.291 g, 1 mmol). The final mixture was further stirred at room temperature for 1 h. The clear solution was set aside for a week, yielding red small block-shaped single crystals.

Refinement top

The amino H atoms were located in a difference Fourier map and were refined with distance restraints of N—H = 0.90 (1) Å. All other H atoms were positioned geometrically and were constrained as riding atoms, with C—H distances of 0.93–0.96 Å, and Uiso(H) set to 1.2 or 1.5Ueq(C) of the parent atom. Rotating group models were used for the methyl groups. The structure contains voids of 37 Å3.

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.
