Reaction of 4‐amino‐5‐methyl‐1,2,4‐triazol‐3(2H)‐thione (AMTT) and 4‐amino‐6‐methyl‐3‐thio‐3,4‐dihydro‐1,2,4‐triazin‐5(2H)‐one (AMTTO) with 2‐hydroxybenzaldehyde led to the synthesis of corresponding Schiff base ligands [(Z)‐4‐((2‐hydroxybenzylidene)amino)‐3‐methyl‐1H‐1,2,4‐triazole‐5(4H)‐thione (L1) and (Z)‐4‐((2‐hydroxybenzylidene)amino)‐6‐methyl‐3‐thioxo‐3,4‐dihydro‐1,2,4‐triazin‐5(2H)‐one (L2)]. Treatment of synthesized Schiff base ligands with CuCl provided the complexes [Cu(L1)3Cl] (1) and [Cu(L2)2Cl] (2). Synthesized complexes were characterized by elemental analyses, IR spectroscopy and X‐ray diffraction studies. Complex 1 consists of a metal ion coordinated with one chloride ion and three Schiff base ligands via sulfur atoms in a distorted tetrahedral environment, whereas 2 consists of a metal ion coordinated with one chloride ion and two sulfur atoms from two different Schiff base ligands in a trigonal planar arrangement. Crystal data for 1 at –153 °C revealed an orthorhombic space group Fdd2, a = 34.8088(7), b = 33.8156(8), c = 11.6142(2) Å, Z = 16, R1 = 0.0357; for 2 at –178 °C the symmetry was triclinic, space group P1, a = 7.27520(10), b = 15.4620(2), c = 23.7985(4) Å, α = 72.1964(13), β = 86.5208(12), γ = 89.8597(11)°, Z = 4, R1 = 0.0359.

4-氨基-5-甲基1,2,4-三唑-3(2H)-硫酮(AMTT)与4-氨基-6-甲基-3-硫-3-,4-二氢-1,2的反应4-三嗪-5(2H)-一(AMTTO)与2-羟基苯甲醛可合成相应的席夫碱配体[(Z)-4-(((2-羟基苄叉基)氨基)-3-甲基-1H-1, 2,4-三唑-5(4H)-硫酮(L1)和(Z)-4-(((2-羟基亚苄基)氨基)-6-甲基-3-硫代-3,4-二氢-1,2,4 -triazin-5(2H)-1(L2)]。用CuCl处理合成的席夫碱配体提供了[Cu(L1)3 Cl](1)和[Cu(L2)2 Cl](2)的配合物。通过元素分析,红外光谱和X射线衍射研究对合成的复合物进行表征。复杂1由扭曲的四面体环境中的一个硫离子与一个氯离子和三个席夫碱配体配位的金属离子组成,而2由一个离子中的两个氯离子和来自两个不同席夫碱配体的两个硫原子配位的金属离子组成平面布置。在–153°C下1的晶体数据显示正交空间群Fdd 2,a = 34.8088(7),b = 33.8156(8),c = 11.6142(2)Å,Z = 16,R 1 = 0.0357;对于–178°C下的2,对称性是三斜的,空间群P 1a= 7.27520(10),b = 15.4620(2),c = 23.7985(4)Å,α = 72.1964(13),β = 86.5208(12),γ = 89.8597(11)°,Z = 4,R 1 = 0.0359。
