2、通过x一射线单晶’珩射、热重以及红外光谱对其进行了表征。结果显示晶体1为单斜晶系,P2/c空间群。晶体2为单斜晶系,C2/c空间群。配合物2为2D一2D穿插结构。热重分析表明配合物1和2分别在343和325时分解。关键词:镉配位聚合物;双咪唑;水热法中图分类号:0614.24+2文献标识码:A文章编号:1001.-4861(2014)11-2584.-07DoI:10.11862/CJIC.2014.348Synthesis,CrystalStructuresandPropertiesof2DCadmiumCoordinationPolymersConstructedfromP-.Pht
