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。
Hydrothermal synthesis of holmium perchlorate and p-toluenesulfonylglycine 1: 3 type complexes [Ho2 (TsGyHH6 (H2O) 4] n.4nH2O. The complex crystal belongs to the triclinic system with P i space group. The unit cell parameters are: a = 1.3927 (1) nm, b = 1.6645 (2) nm, c = 1.6485 nm, α = 73.93 ° β = 76.42 (1) γ = 75.42 (1) ° V = 5.569 (7) nm3 Z = 2 D c = 1.623 mg / m 3 M r = 1746.04 F 000 = 1806 Rl = 0.0274, wR2 = 0.0553. The Ho (III) ions in each dimeric unit [Ho2 (TsGlyH) 6 (H2O) 4] are linked by the carboxy bridges of four p-toluenesulfonyl glycinates while each Ho (III) ion in the dimeric unit And further connected to adjacent rare earth ions through two other carboxyl bridges to form a one-dimensional chain structure.
