2-Naphthylamine (1 mmol, 143.19 mg) was dissolved in hot methanol (10 ml) and added in portions to a methanol solution (3 ml) of salicylaldehyde (1 mmol, 0.11 ml). The mixture was then stirred at 323 K for 2 h. Subsequently, an aqueous solution (2 ml) of zinc acetate dihydrate (1 mmol, 219.5 mg) was added dropwise and stirred for another 5 h. The solution was held at room temperature for ten days, whereupon yellow blocks of (I) were obtained.
All the H atoms were geometrically placed (C—H = 0.93 Å) and refined as riding with Uiso(H) = 1.2Ueq(C).
As part of our ongoing studies of Schiff bases, we report here the synthesis and crystal structure of the title compound, (I), (Fig. 1), a new zinc(II) complex with a bidentate Schiff base ligand derived from the condensation of salicylaldehyde and 2-naphthylamine.
The coordination around zinc is a distorted tetrahedon involving two O and N atoms of the ligands (Table 1). These bond lengths and angle values are similar to the reported values for related structures (Hokelek et al., 2000, Tatar et al., 1999).
In the crystal of (I), the relatively short intermolecular distances H17···Cg(1)i of 2.945Å and H4···Cg(2)ii of 2.947Å (symmetry code: (i) 1/2 + x, 1/2 - y, -1/2 + z; (ii) x - 1, y, z; Cg(1) and Cg(2) are the centroids of the C25–34 and C29–34 rings, respectively) indicate the presence of weak C—H···π interactions (Fig. 2), which stabilize the crystal packing along with van der Waals forces.

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. |

As part of our ongoing studies of Schiff bases, we report here the synthesis and crystal structure of the title compound, (I), (Fig. 1), a new zinc(II) complex with a bidentate Schiff base ligand derived from the condensation of salicylaldehyde and 2-naphthylamine.
The coordination around zinc is a distorted tetrahedon involving two O and N atoms of the ligands (Table 1). These bond lengths and angle values are similar to the reported values for related structures (Hokelek et al., 2000, Tatar et al., 1999).
In the crystal of (I), the relatively short intermolecular distances H17···Cg(1)i of 2.945Å and H4···Cg(2)ii of 2.947Å (symmetry code: (i) 1/2 + x, 1/2 - y, -1/2 + z; (ii) x - 1, y, z; Cg(1) and Cg(2) are the centroids of the C25–34 and C29–34 rings, respectively) indicate the presence of weak C—H···π interactions (Fig. 2), which stabilize the crystal packing along with van der Waals forces.
