摘要
[Bi(SCN2H4)5(NO3)](NO3)2H2O是在水溶液中由硫脲与硝酸铋(Ⅲ)以摩尔比5:1反应合成.晶体结构由单晶X-射线衍射分析测定,晶体属于三斜晶系,P-1空间群,晶胞参数a=9.284(1)nm,b=9.783(1)nm,c=13.995(2)nm;α=80.7 02(2)°,β=84.092(2)°,γ=86.334(2)°.Z=2,V=1.2463(3)nm3,R1=0.050,wR2=0.104.在[Bi(SCN2H4)5(NO3)](NO3)2 H2O中铋原子被五个硫脲分子中的硫原子及硝酸根离子中的两个氧原子包围形成一个歪曲的单帽三棱柱结构.
The complex nitratopentathioureabismuth(Ⅲ) dinitrate hydrate was synthesized by reaction of thiourea with bismuth(Ⅲ) nitrate in 5:1 molar ratio in the water solution. The crystal structure was determined by single crystal X-ray diffraction analysis. The crystal belongs to triclinic with space group P -1, a = 9.284(1) nm, b = 9.783(1) nm, c = 13.995(2) nm, a = 80.702(2)° , P = 84.092(2)° , Y ( = 86.334(2)° , Z = 2, V=l.2463(3) nm3, R,=0.050, wR2=0.104. In nitratopentathioureabismuth(Ⅲ) dinitrate hydrate, the Bi atom is surrounded by five S atoms of five thiourea molecules and two O atoms of one nitrate anion to form a distorted one-cap tri-prism geometry.
