在甲醇溶液中，将K2NiL·H2O和M(OAC)2(M = Co,Zn)按1:1的摩尔比进行组装反应，得到了镍、钴和镍、锌两种异金属一维链状配位聚合物，其化学组成分别为{[Ni2Co2L2(H2O)2]·CH3OH·3H2O}n（1）和{[Ni2Zn2L2 (H2O)2]·2CH3OH·H2O}n（2），（H4L=2-羟基-3-[(E)-({2-(2-羟基苯甲酰胺基)乙基}亚氨基)甲基]苯甲酸，OAC- = CH3COO-）。通过IR谱，元素分析的方法对其进行了表征，利用X-射线单晶衍射方法对其晶体结构进行了测定，结构分析表明：它们都是由不对称四核单元组成链状配位聚合物。

Two heterometallic chain coordination polymers with the chemical formula {[Ni2Co2L2(H2 O)2]·CH3OH·3H2O}n 1 and {[Ni2Zn2L2(H2O)2]·2CH3OH·H2O}n 2，have been synthesized by the assembly reaction of K2NiL·H2O and M(OAC)2(M = Co,Zn) with a 1:1 mole ratio in methanol, and characterized by elemental analysis, and IR spectra. Where H4L = 2-hydroxy-3-[(E)-({2-[(2-hydroxybenzoyl)imino]ethyl}imino)methyl] benzoic acid, OAC- = CH3COO-. The crystal structures were determined by single-crystal X-ray diffraction analyses, the two compounds have chain molecular structures formed by dissymmetrical tetranuclear units.
