Synthesis and Structure Characterization Research of Bis[N,N-bis(2-hydroxyethyl) dithiocarbamato-κ2S,S']chromium(Ⅲ)

合成了新型晶体配合物二羟乙基二硫代氨基甲酸铬[(HOC2H4)2NCSS]3Cr,对其结构进行解析和表征。用X-射线单晶衍射法测定了晶体的结构,结果表明配合物[(HOC2H4)2NCSS]3Cr晶体属于单斜晶系;空间群为C2/c,晶胞参数:a=17.9410(19),b=10.3755(11),c=14.4284(16),β=113.5710(10)°;晶胞参数比:a/b=1.7293,b/c=0.7191,c/a=0.8042。通过元素分析,红外光谱,紫外分析等表征手段对其结构进行分析,表明其结构均与X-射线单晶衍射法测定的晶体的结构吻合。
