合成了配合物二氯.二[1-对甲氧基苯基-3-(1,2,4三唑-1-基)-1-丙酮-N4]合钴(Ⅱ),并测定了其晶体结构.晶体为单斜晶系,C 2/c空间群,晶胞参数:a=2.100 8(4)nm,b=0.488 88(10)nm,c=2.627 4(5)nm,β=98.10(3),°V=2.671 5(9)nm3,Z=4,Dc=1.473 g/cm3.晶体配合物为C2对称,对称轴通过钴原子,钴原子与来自配体的两个氮原子和两个氯原子配位,形成一个略变形的正四面体结构,测定了其IR及UV-v is光谱性质.

Bis [ 1- （4-methoxyphenyl）-3-（ 1H-1,2, 4-triazol-1-yl ）-1-propanone-N^4 ] dichorocobalt （ Ⅱ ） complex was synthesized and the crystal structure determined by X-ray crystallography. It crystallizes in the monoclinic system, space group C2/c group, with lattice parameters a= 2. 100 8（4） nm, b=0. 488 88（10） nm, c=2. 627 4（5） nm, β=98. 10（3）°, V=2. 671 5（9） nm^3, Z=4, Dc=1. 473 g/cm^3. It has C2 symmetry with its axis through the Co atom, and the Co atom was coordinated by two N atoms of the 1-（4-methoxyphenyl）-3-（1H-1, 2, 4-triazol-1-yl）-1- propanone ligands and two Cl^- atoms, forming a slightly distorted tetrahedron. IR and electronic spectra study of the target complex were carried out.
