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。
In this paper, a novel ternary terbium sulfate salt (C2H8N) [Tb (SO4) 2.H2O] (1) was synthesized by solvothermal method and characterized by XRD, IR, It is characterized by elemental analysis. The crystal belongs to the monoclinic space group P21 / n. Where 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 and Z = 4. The framework structure of compound 1 consists of TbO8 polyhedrons and SO4 tetrahedrons. S (1) and S (2) are linked to Tb (1) and double-stranded by three S-O-Tb linkages, while adjacent double strands are connected by μ3-O (O5) to form a new ladder.
