一个新颖的N,N-二(1-甲基咪唑基-1-亚甲叉)-β-丙氨酸甲酯二氯化钴(Ⅱ)配合物被合成得到,并通过元素分析与X-射线单晶衍射手段对其结构进行了表征.晶体属于三斜晶系,P-1空间群,其中a=7.4540(9),b=10.2345(13),c=13.5999(17)(A),α=102.884(2),β=102.657(2),γ=107.548(2)v,V=917.4(2)(A)3,Mr=421.19,Z=2,Dc=1.525 g/cm3.单晶结构分析表明,钴(Ⅱ)被两个氯原子、两个咪唑环的氮原子与叔胺的氮原子所配位,构成一新颖的五配位的三角双锥配位环境,通过碳上的氢原子与氯原子和酯基的氧之间形成的非典型氢键使得分子构成三维的空间结构.

A new complex CoLCl2(L=N,N-bis[(1-methylimidazol-2-yl)methyl]alanine methylester)was synthesized and its crystal structure was determined by single-crystal x-ray diffraction.Crystal data:C14H21Cl2CoN5O2,triclinic,space group P-1 with a=7.4540(9),b=10.2345(13),c=13.5999(17)(A),α=102.884(2),β =102.657(2),γ=107.548(2)v,V=917.4(2)(A)3,Mr=421.19,Z=2,Dc=1.525 g/cm3,F(000)=434,μ=1.243 mm-1,the final R=0.0500 and wR=0.0712 for 2519 observed reflections(I 2(Ⅰ)).The Co (Ⅱ)atom wsa coordinated in trigonal bipyramid geometry by two chloride atoms,two imidazole nitogen atoms and a tertiary amine N atom.Structure analysis indicated that the structure was consolidated by some non-classical intermolecular and intramolecular weak hydrogen bonds which formed a three dimensional network in the solid.
