摘要
通过-3-硝基-1,2,4-三唑-5-酮(NTO)的锂盐水溶液与硫酸镍水溶液反应,制备了标题配合物,用TG-DTG、元素分析、13CNMR分析和红外光谱对它进行了表征,其结构用X射线单晶分析法测定,所得晶体学多数为:a0.9255(2)nm,b1.4133(2)um,c0.6465(1)um,β88.42(2)°,V0.8452um3,Z2,Dc1.819g·cm-3,μ12.382cm-1,F(000)480;晶体属单斜晶系,空间群为P21/c,最终偏离因子R为0030。根据TG-DTG和FT-IR技术得到的分析结果,提出了线性升温条件下标题配合物的热分解机理。
[Ni(H2O)6] (NTO)2·2H2O was prepared by mixing the aqueous solution of lithium 3-nitro-1, 2, 4-triazol-5-onate and nickel sulfate. It was characterized by thermal analysis, elementalanalysis,13 CNMR and IR measurement. The crystal belongs to space group P21/c with crystalparameters of a=0. 925 5(2), b= 1. 413 3(2), c=0. 646 5(1 )nm, β=88. 42(2)°, v=0. 845 2 nm3, z=2, Dc=1. 819 g·cm-3, μ=12. 382 cm-1, F(000) =480. The final R is 0. 030. Based on the thermalanalysis, the thermal decomposition mechanism of [Ni(H2O)6] (NTO)2·2H2O has been derived.
