【摘要】 <正> 我们曾经对二硫代乙酰丙酮和多种金属离子的配合反应进行了系统的研究.在成功合成（C₅H₇S₂）₂[CuBr₃]的基础上,最近我们试图用类似方法合成（C₅H₇S₂）[CuI₃].但对产物晶体的X 射线衍射分析结果却表明,所得到的化合物的分子式为（C₅H₇S₂）₂[Cu₃I₅].[Cu₃I₅]^2-是以[CuI₃]配位三角形和两个相邻[CuI₄]配位四面体连接的无限链状配合阴离子形式存在.更多还原

【Abstract】 The crystal structure of the title compound has been determined from single-crystal X-ray diffractometer data.（C₅H₇S₂）₂[Cu₃I₅]crystallizes in space group I 2/awith α=18.126（12）,b=9.302（2）,c=14.275（2）（?）,β=101.51（1）°and z= 4.The full-matrix least-squares refinement gave R=0.043 for 1820 observed[I>3.0σ（I）]re-flections.The crystal structure consists of（C₅H₇S₂）cations and[Cu₃I₅]_∞ anions ofinfinite I-bridged chains,the repeat unit of which contains one three-coordinatedcopper（I）atom,the ligand configuration being approximatively trigonal planar,andtwo four-coordinated copper（I）atoms,possessing the ligand configuration of tetra-hedron.The Cu—Cu distances are 2.528（2）and 2.557（2）（?）,respectively.更多还原
