Magnetic and spectral data support a square-planar structure for [Cu(NNS)X] (X = Cl, Br, NO 3 , CH 3 COO) and a distorted octahedral structure for [Cu(NNS) 2 ] · 0.5H 2 O. The crystal and molecular structure of [Cu(NSS)Cl] has been determined by X-ray diffraction. This complex has a distorted square-planar geometry with the copper(II) ion lying in an approximate plane of four coordinating atoms, three of which
摘要通式为[Cu(NNS)X]·xH 2 O(NNS =由6-甲基吡啶-2-醛与硫代氨基脲缩合形成的带负电荷的三齿配体的铜(II)配合物; X = Cl,Br,NO 3和CH 3 COO; x = 0,1)和[Cu(NNS)2]·0.5H 2 O已制备并通过电导,磁,电子和红外光谱测量表征。磁性和光谱数据支持[Cu(NNS)X]的正方形平面结构(X = Cl,Br,NO 3,CH 3 COO)和[Cu(NNS)2]·0.5H 2 O的扭曲八面体结构通过X射线衍射确定了[Cu(NSS)Cl]的晶体和分子结构。该配合物的方形几何结构扭曲,铜(II)离子位于四个配位原子的近似平面中,其中三个来自6-甲基吡啶-2-羧甲醛硫代半脲,而第四个配位位点则被氯化物配体占据。硫半脲酮以硫醇盐形式存在,并通过吡啶氮原子,偶氮甲碱氮原子和硫醇硫原子与铜(II)离子配位。版权所有©1996 Elsevier Science
