摘要
Complex [Mn（tce） 0.5（H2O） 4]（1） was obtained from Mn（OAc） 2 and tce,where tce is 1,1,2,2-tetracarboxyl-ethane. The structure of 1 is a single molecule,in which Mn（II） is a distorted octahedron coordinated to six oxygen atoms. Complex [Cd（tce） 0.5（H2O） 3]（H2O） （2） fea-tures a pillared layer architecture. The Cd（II） atom is in an octahedral environment coordinated by six oxygen donors from water molecules and tce ligands. Cd（II） atoms are interlinked by the tce ligand to generate a 2-D wavelike layer. The layers are strutted by the intermolecular O-H···O hydrogen bonds to form a 3-D open framework. Luminescence property of complex 2 was investigated. Magnetic property of complex 1 was also studied. 1 belongs to triclinic,space group P1 with a = 6.2901（12） ,b = 8.0212（15） ,c = 8.0769（15） A,α = 108.522（3） ,β = 95.068（3） ,γ = 97.086（3） °,V = 379.92（12）A^3,Mr = 456.08,Dc = 1.993 g/cm^3,F（000） = 232,μ = 1.748 mm^-1,Z = 1,the final R = 0.0297 and wR = 0.0731 for 1575 observed reflections with I 〉 2σ（I） . 2 is of monoclinic system,space group P21/c with a = 6.4367（14） ,b = 9.495（2） ,c = 13.907（3）A,β = 117.405（8） °,V = 754.6（3） A^3,Mr = 285.51,Dc = 2.513 g/cm^3,F（000） = 556,μ = 2.905 mm^-1,Z = 4,the final R = 0.0375 and wR = 0.0737 for 1521 observed reflections with I 〉 2σ（I）.
