在水热条件下,2-甲基咪唑4,5-二羧酸(H3MIDC)与醋酸钴反应,合成了新的[CO8(HMIDC)12]8-立方体结构单元的多核杂金属配合物(1),其结构经单晶x-射线衍射和元素分析表征.1属三方晶系,R-3空间群,晶胞参数a=24.407 9(17)(A),b=24.4079(17)(A),c=25.140(3)(A),α=90°,β= 90°,γ=120°,V=12971(2)A3,Z=45,Mr=272.12,Dc=1.568 Mg·m-3,μ=1.510 mm-1.F(000)=6210,GOF=1.347,Rint=0.0851,Ri=0.0848,wR2=0.2544.12个配体将8个Co离子连接成-个立方体结构,12个Na(I)离子连接相邻的立方体结构形成一个三维的超分子结构.%A novel [ Co8 (HMIDC)12 ] 8- cubic mutil-core hybrid metal complex( 1 ) was synthesized based on ligand 2-methyl-lH-imidazole-4 ,5-dicarboxylic acid(H3MIDC) and cobalt acetate in hydrothermal. The structure was characterized by elemental analysis and single crystal X-ray diffraction. 1 belongs to rhombohedral, space group R-3 with a =24.407 9(17) (A°), b =24.407 9(17) (A), c =25.140(3) (A°), o=90°, β= 90°, r= 120°, V=12971(2) (A°)3, Z=45, Mr=272.12, Dc=1.568 Mg· m-3,μ=l.510 mm-1, F(000) =6210, GOF=1.347, Rint =0.085 1, R1 =0.084 8, wR2 = 0.254 4. Eight cobalt ions connected into a cubic structure by twelve ligands, and twelve Na( I ) ions connected adjacent cubic structure to a three-dimensional supramolecular structure.
