摘要

金属配体[CuL](H2L=水杨醛缩甘二肽席夫碱)和MgSO4在水-甲醇混合溶液中合成了一个Cu(Ⅱ)-Mg(Ⅱ)杂核配合物[Mg(H2O)4 (CuL)2]·4H20.用元素分析、红外光谱等手段对标题配合物的组成和结构进行了表征.该配合物属于三斜晶系,空间群是P-1,晶胞参数a=7.537(1)(A),b=9.127(2)(A),c=11.728(2)(A),a=73.55(1)°,β=72.43(1)°,γ=84.29(1)°.%Metal ligand [CuL]-(H2 L=salicylaldehyde dipeptide Schiff base) and MgSO4 synthesize a Cu(Ⅱ)-Mg(Ⅱ) heteronuclear complex [Mg(H2O)4 (CuL)2] · 4H2O in water-methanol mixed solution.This paper characterizes the composition and structure of the title complex with elemental analysis and infrared spectroscopy.This complex belongs to triclinic system.Space group is P-1.Cell parameters are α=7.537(1)(A),b=9.127(2)(a),c=11.728(2)(a),α=73.55(1)°,β=72.43(1)° and γ=84.29(1)°.
