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),α=102.884(2),β=102.657(2),γ=107.548(2)o,V=917.4(2)3,M r=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 novel cobalt (II) complex of N, N-bis (1-methylimidazolyl-1-methyleneidene) -β-alaninate was synthesized and characterized by elemental analysis with X- The crystal belongs to the triclinic system P-1 space group, in which a = 7.4540 (9), b = 10.2345 (13), c = 13.5999 (17), α = 102.884 (2), β = 102.657 (2), γ = 107.548 (2) o, V = 917.4 (2) 3, M r = 421.19, Z = 2 and Dc = 1.525 g / cm3. (II) is coordinated by two chlorine atoms, the nitrogen atoms of the two imidazole rings are coordinated with the nitrogen atom of the tertiary amine to form a novel pentacoordinated triangular bipyramid coordination environment. The coordination of hydrogen atoms and carbon atoms The atypical hydrogen bonds formed with the oxygen of the ester group allow the molecules to form a three-dimensional spatial structure.
