摘要
采用水热方法合成高氯酸钬与对甲苯磺酰甘氨酸1∶3型配合物[Ho2(TsG lyH)6(H2O)4]n.4nH2O。配合物晶体属三斜晶系,P i空间群,晶胞参数为:a=1.3927(1)nm,b=1.6645(2)nm,c=1.6485(2)nm,α=73.93(8),°β=76.42(1),γ=75.42(1),°V=5.569(7)nm3,Z=2,D c=1.623 mg/m3,M r=1746.04,F(000)=1806,Rl=0.0274,wR2=0.0553。每一个二聚单元[Ho2(TsG lyH)6(H2O)4]中的Ho(III)离子由四个对甲苯磺酰甘氨酸的羧基桥相连,同时二聚单元中的每一个Ho(III)离子再进一步通过另外两个羧基桥与邻近的稀土离子相连,从而构成一维链状结构。
The title complex [Ho2(TsGlyH)6(H2O)4]n·4H2O ( TsGlyH2 = N - p - tolysulfonyl glycine ) was hydrothermaUy synthesized and characterized by single crystal X - ray diffration analysis. The crystal structure belongs to triclinic system,space group Pi) ,with a=1.3927(1)°,V=5.569(7)nm^3,Z =2,Dc = 1.623 g/cm^3,Mr = 1746.04,F(000) = 1806. The dimeric units of [ Ho2 (TsGlyH) 6·4H2O ] are bridged by four bidentate bridging carboxylate groups between Ho( 1 ) and Ho(2) to give a B'A'ABB" A" chain. Each Ho(m) of the dimeric unit is linked with another Ho(Ⅲ) ion by bridging bidentate carboxylate groups to form a I - D chain.
