由1-正丁基咪唑(C_7H_(12)N_2)和氯化钴(CoCl_2)合成了一种新的配合物1-正丁基咪唑合钴配合物[Co(C_7H_(12)N_2)_6]Cl_2。采用元素分析、红外光谱和X射线单晶衍射对配合物结构进行了表征。结果表明,所合成的配合物C_(42)H_(72)Cl_2CoN_(12)属于单斜晶系,空间群P2,晶胞参数:a=8.540(3)nm,b=16.851(5)nm,c=17.237(5)nm;α=90.00°,β=104.037(5)°,λ=90.00°;V=2406.5(13)nm^3,Z=2,Dc=1.207g·cm^(-3),F(000)=938,μ=0.509mm^(-1),R_1=0.0526,wR_2=0.1664。

A new 1-n-butyl-imidazole cobalt complex [Co （C7H12N2）6]Cl2 were synthetized by CoCl2 and 1-n-butyl-imidazole （C7H12N2）. The structure of complex was characterized by elementary analysis, IR spectra and X-ray diffraction. The results showed that synthetized complex C42H72Cl2CoN12 belonged to monoclinic system, space group P2, cell parameters were as follows： a=8. 540（3）nm,b= 16. 851（5）nm,c= 17. 237（5）nm;a= 90. 00°,β= 104. 037 （5）°,λ=90.00°; V=2406.5（13）nm^3,Z = 2,Dc= 1. 207g · cm^-3, F（000） = 938,μ = 0. 509mm^-1, R1 = 0. 0526, wR2=0. 1664.
