| 摘要: 本文采用溶剂热法合成了一种具有梯状链结构新的有机模板硫酸铽盐：(C2H8N)[Tb(SO4)2·H2O] (1)，并通过X-射线衍射、红外、热重及元素分析对其进行了表征。该晶体属于单斜晶系，P21/n空间群。其中a=0.568 1(3) nm，b=1.972 7(10) nm，c=0.862 7(4)nm，β=90.658(6)°，V=0.966 7(8) nm3，Z=4。化合物1的骨架结构由TbO8多面体和SO4四面体构成。S(1)和S(2)与Tb(1)相连接，通过3个S-O-Tb连接构成双链，而相邻的双链通过μ3-O(O5)连接形成一个新的梯状链。 |

| Abstract: A organic amine templated 1D terbium sulfate (C2H8N)[Tb(SO4)2·H2O] (1) has been synthesized under solvothermal condition and structurally characterized by single-crystal X-ray diffraction, IR, TGA and ICP. The single-crystal X-ray analysis of compound 1 reveals that the crystal belongs to monoclinic, space group P21/n with a=0.568 1(3) nm, b=1.972 7(10) nm, c=0.862 7(4) nm, β=90.658(6)°, V=0.966 7(8) nm3, Z=4. The structure of framework 1 is constructed from TbO8 polyhedra and SO4 tetrahedra. S(1) and S(2) connect Tb(1) and its crysta-llographic partners by using three S-O-Tb linkages to generate double chains, whereas the adjacent double chains are connected by μ3-O (O5) to form a novel ladder-like chains.
