摘要
配合物晶体MnHg(SCN) 4 中维系晶体结构的化学键是—Mn—NCS—配位键。从MnHg(SCN) 4 晶体中配位键的分布特点出发 ,对属于点群 4的单形四方四面体、四方柱和平行双面进行分析 ,确定晶形中不能出现平行双面{ 0 0 1}、四方柱 { 110 } ,可以出现的单形为四方四面体 { 10 1}和 { 0 11}及四方柱 { 10 0 } ,而且四方四面体 { 10 1}和 { 0 11}单形最发育。由结构分析得出的晶形特点与实际晶体晶形特点相符。
The chemical bonds of holding the structures in the complex MnHg(SCN) 4 are -Mn-NCS- coordinate bonds.From the distributing characteristics of weak bonds in MnHg(SCN) 4 crystal,the single forms,square tetrahedron,square post,and parallel double faces,which belong to 4 crystal class,were analyzed.The results indicate that the parallel double face {001} and square post {110} could not exist in the crystal forms,but the square tetrahedron {101},{011} and square post {100} are emergent single forms,and the square tetrahedron {101} and {011} are best developed single forms. The characteristics of crystal morphology based on the structural analyses are the same as practical crystals.
