摘要 The title complex Zn(HL)(NCS)2 (C14H18N4OS2Zn, Mr = 387.81, HL = N-(3-dimethyl-aminopropyl)-salicylaldimine) has been synthesized by the reaction of ZnSO4·7H2O with the Schiff base N-(3-dimethylaminopropyl)-salicylaldimine derived from the condensation reaction of 3-dimethylamino- 1-propylamine with salicyladehyde. It crystallizes in the monoclinic system, space group P21/n with a = 9.8360(8), b = 14.930(1), c = 12.277(1) A, β= 101.455(2)°, V= 1767.0(3) A 3, Z = 4, F(000) = 800, Dc= 1.458 g/cm^3 and ,μ(MoKα) = 1.631 mm^-1. The structure was refined to R = 0.0463 and wR = 0.1065 for 2681 observed reflections (1 〉 2σ(I)). Crystal analyses revealed that the Zn(Ⅱ) atom is coordinated by two nitrogen atoms of two NCS^-, and an oxygen atom as well as a nitrogen atom of amine from the neutral Schiff base ligand of N-(3-dimethyl-aminopropyl)-salicylaldimine to give a distorted tetrahedral geometry.
