摘要
合成１，２—二氰基，二硫甲基乙烯［Ｃ６Ｈ６Ｓ２Ｎ２］，进行了１ＨＮＭＲ谱定性分析，并用Ｘ射线衍射法测定该化合物的晶体结构．该晶体的结构参数ａ＝１４．２４７７（２８），ｂ＝１２．７２５９（２８），ｃ＝９．２６２７（２４）×１０－１０ｍ，β＝１０２．８９（２），ｄ密度＝１．３８３ｇ／ｃｍ３，Ｚ＝８，属Ｐ２空间群，为单斜晶系．通过键长、键角的分析，阐明该分子骨架为近平面结构，分子呈蛙形。
This paper discusses the preparation of 1,2-dicyano-disumethyl-ethylene and its crystal structure determined by X-ray diffraction method.The parameters of its crystal structure are:a=14.2477(28),b=12.7259(28),c=9.2627(24)×10 -10 m,β=102.89(2) ,d x=1.383g/cm 3,and Z=8.This Compound belongs to P2 vacuity group and monoclinic system.The molecule exists in a frog-shaped conformation and has a strong coordination affinity.
