In the title compound, [ZnCl2(C12H11N3)], the ZnII atom is four-coordinated by two N atoms from an N-(2-pyridylmethylene)benzene-1,4-diamine ligand and two Cl atoms in a distorted tetrahedral geometry. In the crystal, the complex molecules are connected by N—H⋯Cl and C—H⋯Cl hydrogen bonds into a two-dimensional layer structure parallel to (110).

The ligand was prepared according to the previous method (Ye et al., 2005). 1,4-Diaminobenzene (1.08 g, 10 mmol) was dissolved in methanol (20 ml), followed by addition of 2-pyridine carboxaldehyde (4.24 mg, 40 mmol). The mixture was stirred at room temperature for 2 h and filtered. The resulting yellow crystalline solid was washed with methanol several times and dried in air. A solution of ZnCl2.2H2O(14 mg, 0.08 mmol) in acetonitrile (5 ml) was allowed to diffuse slowly into a methylene chloride solution (10 ml) of the ligand (0.179 g, 0.625 mmol) in an H-shaped tube. Colorless crystals were obtained over a week.
H atoms bonded to C3, C4 and C11 were located from a difference Fourier map and refined isotropically. The other H atoms were positioned geometrically and refined as riding atoms, with C—H = 0.93 and N—H = 0.86 Å and with Uiso(H) = 1.2Ueq(C,N).
Based on the design and syntheses of zinc Schiff-base complexes and the potential applications of these materials as fluorescent probes (Su et al., 1999; Ye et al., 2005), the title compound has been obtained. As shown in Fig. 1, the
contains one ZnII ion, one N-(pyridin-2-ylmethylene)benzene-1,4-diamine ligand and two Cl atoms. The ZnII atom exhibits a distorted tetrahedral coordinate geometry formed by two N atoms from the ligand and two Cl atoms, with the Zn—N distances of 2.057 (3) and 2.070 (3)Å and the Zn—Cl distances of 2.2000 (13) and 2.2456 (12) Å. As shown in Fig. 2, the complex molecules are connected into a two-dimensional supramolecular layer-like structure via weak N—H···Cl and C—H···Cl hydrogen-bonding interactions (Table 1).For general background to zinc(II) complexes with Schiff base ligands, see: Su et al. (1999); Ye et al. (2005).

Based on the design and syntheses of zinc Schiff-base complexes and the potential applications of these materials as fluorescent probes (Su et al., 1999; Ye et al., 2005), the title compound has been obtained. As shown in Fig. 1, the asymmetric unit contains one ZnII ion, one N-(pyridin-2-ylmethylene)benzene-1,4-diamine ligand and two Cl atoms. The ZnII atom exhibits a distorted tetrahedral coordinate geometry formed by two N atoms from the ligand and two Cl atoms, with the Zn—N distances of 2.057 (3) and 2.070 (3)Å and the Zn—Cl distances of 2.2000 (13) and 2.2456 (12) Å. As shown in Fig. 2, the complex molecules are connected into a two-dimensional supramolecular layer-like structure via weak N—H···Cl and C—H···Cl hydrogen-bonding interactions (Table 1).
