摘要(Abstract)：
用扩散法合成了配合物[NdCo(NTA)2(H2O)11/3(CH3OH)1/3]·(CH3OH)2/3.10/3H2O(1),晶体属三斜晶系,空间群为P1,晶胞参数为a=0.963 6(2)nm,b=1.044 9(2)nm,c=1.339 3(2)nm,α=107.04°,β=98.25(2)°,γ=103.98°,V=1.217 2(4)nm3,Z=2,配合物具有三维网络结构。配合物[Nd2Co3(EDTA)3(H2O)11·12H2O](2)用水热法获得,属单斜晶系,空间群为C2,晶胞参数为a=1.592 5(3)nm,b=1.465 5(2)nm,c=1.474 1(2)nm,β=116.407(2)°,V=3.081 3(8)nm3,Z=2。每个Nd3+通过羧基桥联3个Co2+,而每个Co2+与两个相邻Nd3+连接构成12员环从而形成二维杂金属层,相邻层之间通过水的氢键作用连接形成三维结构。
