A cobalt coordination polymers [Co(dib)(SO4)] (1) was obtained by solvothermal assembly of CoSO4· 7H2O with sodium formate in the presence of N-donor ligands,namely 1,4-di(1-imidazolyl)benzene (dib).Compound 1 crystallizes in monoclinic system,space group C2/c with a=1.972 26(7) nm,b=0.977 0(3) nm,c=1.1839 6(4) nm,β=96.479(2)°,V=2.266 8(13) nm3,Z=4,C24H20N8CoO4S,Mr=575.47,Dc=1.686 g·cm-3,μ=0.903 mm-1,F(000)=1 180,Rint=0.018 3,R=0.024 6,wR=0.072 6.Single-crystal X-ray diffraction analysis revealed that each dib ligand in turn uses its two imidzole groups to connect two metal centers,then the two-dimensional (2D) layer is formed.On the other hand,the 2D layers are further connected by sulfate to give a three-dimensional (3D) pcu topologic structure.In addition,the magnetic property of complex 1 has been investigated in the temperature range of 1.8～300 K,and the results show the weak antiferromagnetic interactions between Co(Ⅱ ) ions bridged by sulfate.CCDC:878879.
