Abstract top

The monomeric title nickel(II) complex of a salicylaldimine, [Ni(C20H14N2O4)]·2CH3OH, was obtained by the reaction of 2,4-dihydroxybenzaldehyde and 1,2-phenylenediamine with nickel(II) acetate. The NiII atom is coordinated by two N atoms [Ni-N = 1.839 (2) Å] and two O atoms [Ni-O = 1.8253 (19) Å] in an approximately square-planar geometry. In the crystal structure, intermolecular O-H...O hydrogen bonds link the molecules into a chain along [001].

Comment top

Nickel complexes have attracted intensive interest in the past decade because they play important roles in bioinorganic chemistry and redox enzyme systems (Amirnasr et al., 2006). In a continuation of a study of Schiff base ligands and their nickel(II) complexes, we report here the title complex (Fig. 1), in which the main plane being formed by the three phenyl and the N2O2. The angles O1—Ni1—N1A and O1A—Ni1—N1 (177.30 (10)°) indicate that the coordination geometry of the nickel atom is four-coordinate in an approximately square planar, which acts as a tetradentate ligand through its o-phenylenediamine N atoms and its deprotonated phenol O atoms. This square planar geometry is the most usual for NiII complexes (Shi et al., 2004) in the N202 donor set with Schiff base ligands. The Ni—O distances of 1.8253 (19)Å are very close to the corresponding values in related structures(1.820 Å, Chen et al., 2009). However, the Ni—N distances of 1.8392 (2)Å are significantly shorter than that for a related complex (1.859 Å, Hemindez-Molina et al., 1997). As shown in Fig. 2, intermolecular O—H···O hydrogen bonds (Table 1) link the molecules into a one-dimensional chain along [0 0 1] direction (Zhang et al., 2009).

Experimental top

o-Phenylenediamine(1 mmol, 108.22 mg) was dissolved in hot methanol (20 ml) and added dropwise to a methanol solution (10 ml) of 2,4-dihydroxybenzaldehyde (2 mmol, 276.2 mg). The mixture was then stirred at 323 K for 4 h. The triethylamine solution (3 ml) of nickel (II) acetate (1.5 mmol, 292.2 mg) was then added dropwise and the mixture stirred for another 4 h, at which point a red precipitate collected by suction filtration and washed with ethanol and ether. Crystals of the title compound suitable for X-ray analysis were from the methanol and dimethylsulfoxide solution after about one week.

Refinement top

All H atoms were placed geometrically and treated as riding on their parent atoms with C—H = 0.96 Å (methylene) or 0.93 Å (aromatic), 0.82 Å (hydroxyl) and Uiso(H) = 1.2Ueq(C).

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.
