摘要 报道了具有菱形隧道的配位聚合物:[Nd2(C8H5NO4)3·4H2O]∞的单晶结构.它有两个晶体学独立的金属Nd(Ⅲ)离子中心,每个金属Nd(Ⅲ)离子处于8配位的环境中.8个配位的氧原子中7个氧原子来源于6个5-氨基间苯二甲酸有机配体,另一个氧原子由配位水提供.羧基通过η1,1和η1,3方式连接两个Nd3+.晶体数据:三斜晶系,空间群P1,a=1.03680(5)nm,b=1.66934(15)nm,c=0.88221(14)nm,α=99.754(2)℃,β=111.169(4)°,γ=85.400(4)°.一部分配体在平行于ab面连接金属Nd(Ⅲ)形成分子梯,另一部分配体沿着c轴分子梯构成菱形隧道,同时配位水分子和氨基悬挂在隧道中.
