2-Hydroxy-1-naphthaldehyde (0.1 mmol, 17.0 mg), 2-morpholin-4-ylethylamine (0.1 mmol, 13.0 mg), ammonium thiocyanate (0.1 mmol, 7.5 mg), and Ni(NO3)2.6H2O (0.1 mmol, 29.0 mg) were dissolved in a methanol solution (10 ml). The mixture was stirred at room temperature for 30 min to give a red solution. After keeping the solution in air for 8 days, red block-like crystals were formed.
H atoms were placed in calculated positions and constrained to ride on their parent atoms, with C—H distances in the range 0.93–0.97 Å, and with Uiso(H) = 1.2Ueq(C).
Nickel(II) complexes with Schiff base ligands have received much attention in recent years (Marganian et al., 1995). Some of the complexes have been found to have pharmacological and antitumor properties (Harrop et al., 2003; Brückner et al., 2000; Ren et al., 2002). Nickel is also present in the active sites of several important classes of metalloproteins, as either a homodinuclear or a heterodinuclear species. We have recently reported a few transition metal complexes (Diao, 2007a,b; Diao, Huang et al., 2007; Diao, Shu et al., 2007; Li, Huang et al., 2007). In order to further develop the coordination chemistry of such nickel complexes, we report herein the title new nickel(II) compound.
The NiII atom in the mononuclear complex is four-coordinate in a square-planar geometry with one phenolate O, one imine N, and one amine N atoms of one Schiff base ligand and one terminal N atom of a thiocyanate ligand (Fig. 1). All the bond values (Table 1) subtended at the metal centre are comparable with the values observed in other Schiff base nickel(II) complexes (Arıcı et al., 2005; Usman et al., 2003; Van Hecke et al., 2007; Li, Jiang et al., 2007).

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. |

Nickel(II) complexes with Schiff base ligands have received much attention in recent years (Marganian et al., 1995). Some of the complexes have been found to have pharmacological and antitumor properties (Harrop et al., 2003; Brückner et al., 2000; Ren et al., 2002). Nickel is also present in the active sites of several important classes of metalloproteins, as either a homodinuclear or a heterodinuclear species. We have recently reported a few transition metal complexes (Diao, 2007a,b; Diao, Huang et al., 2007; Diao, Shu et al., 2007; Li, Huang et al., 2007). In order to further develop the coordination chemistry of such nickel complexes, we report herein the title new nickel(II) compound.
The NiII atom in the mononuclear complex is four-coordinate in a square-planar geometry with one phenolate O, one imine N, and one amine N atoms of one Schiff base ligand and one terminal N atom of a thiocyanate ligand (Fig. 1). All the bond values (Table 1) subtended at the metal centre are comparable with the values observed in other Schiff base nickel(II) complexes (Arıcı et al., 2005; Usman et al., 2003; Van Hecke et al., 2007; Li, Jiang et al., 2007).
