Some new tridentate ONO and ONS Schiff base complexes of [NiL(amine)] (L=Salicylidene2-aminophenol and Salicylidene2-aminothiophenol, amine=benzylamine, morpholine, pyrrolidine and piperidine) were synthesized and characterized by IR, UV-vis, (1)H NMR spectroscopy and elemental analysis. The geometry of [NiL(2)(bzlan)] determined by X-ray crystallography indicates that the complex has planar structure and has four coordinate in the solid state. The thermogravimmetry (TG) and differential thermoanalysis (DTA) of the synthesized complexes were carried out in the range of 20-700°C, leading to decomposition of ONO type in two stages and of ONS type in three stages. The ONO and ONS complexes were decomposed to NiO and NiS respectively. Thermal decomposition of the complexes is closely the depends upon nature of the Schiff base ligands and proceeds via first order kinetics.
一些新的三齿 ON 和 ONs 席夫碱配合物[NiL(amine)]（L=水杨醛缩邻氨基苯酚和水杨醛缩邻氨基噻吩，胺=苄胺、吗啉、吡咯烷和哌啶）被合成并通过红外光谱、紫外可见光谱、（1）H NMR 光谱和元素分析进行了表征。X 射线晶体学确定的[NiL(2)(bzlan)]的几何形状表明，该配合物具有平面结构，在固态中具有四配位。所合成的配合物的热重分析（TG）和差热分析（DTA）在 20-700°C 的范围内进行，导致 ON 型配合物分两步分解，ONS 型配合物分三步分解。ONO 和 ONS 配合物分别分解为 NiO 和 NiS。配合物的热分解与席夫碱配体的性质密切相关，通过一级动力学进行。
