以哌嗪为模板剂,在水热条件下合成了一个新的具有二维拓展骨架结构的稀土硫酸盐[C4N2H12]3[Ce2(SO4)6(H2O)2]·H2O,并对其进行了结构表征和热分析.单晶结构解析结果表明,该化合物晶体属于单斜晶系,P21/c空间群,晶体学参数a=0·66335(10)nm,b=2·8088(4)nm,c=1·02212(15)nm,β=96·160(2)°,V=1·8935(5)nm3R1=0·0466,wR2=0·1226.该化合物由[—Ce—S3—Ce—S1—Ce—S3—Ce—S1—]八元环连接形成二维层状结构,无机层间通过氢键连接成三维无限结构.
Using piperazine as a template, a new rare earth sulfate [C4N2H12] 3 [Ce2 (SO4) 6 (H2O) 2] .H2O with a two-dimensional framework structure was synthesized under hydrothermal conditions The crystal structure of the compound belongs to the monoclinic space group P21 / c with the crystallographic parameters of a = 0.66335 (10) nm and b = 2.8088 (4) nm , c = 1.02212 (15) nm, β = 96.160 (2) °, V = 1.8935 (5) nm3R1 = 0.4066, wR2 = 0.1226 This compound is represented by [-Ce-S3- Ce-S1-Ce-S3-Ce-S1-] eight-membered ring connected to form a two-dimensional layered structure, inorganic layers connected by hydrogen bonding into a three-dimensional infinite structure.
