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].4H2O。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),b=9.127(2),c=11.728(2),α=73.55(1)°,β=72.43(1)°,γ=84.29(1)°。 Metal ligand [CuL]-(H2L=salicylaldehyde dipeptide Schiff base) and MgSO4 synthesize a Cu( II )-Mg( 1I ) heteronuclear complex [-Mg(H20)4 (CuL)2-] · 4H20 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 a 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)°
