摘　　要：Two new coordination polymers(Co-CPs),namely{[Co_(8)(DCPN)_(4)(1,2-bimb)4(μ_(3)-OH)_(4)]·(CH_(3)CN)_(0.5)(H_(2)0)_(2)}n(1)and{[Co_(2)(DCPN)(1,3-bimb)(μ_(3)-OH)]H_(2)0}n(2),where H3DCPN=6-(3,5-dicarboxyl-phenyl)nicotinic acid,1,2-bimb=l,2-bis(imidazole-l-methyl)benzene and 1,3-bimb=l,3-bis(imidazole-l-methyl)benzene,have been solvothermally synthesized and structurally characterized by single-crystal X-ray diffraction analysis,elemental analysis(EA),infrared(IR)analysis,powder X-ray diffraction(PXRD)and thermogravimetric analysis(TGA).The structural analysis indicated that 1 is a 2D structure based on two different[Co_(4)(DCPN)_(2)(μ_(3)-OH)_(2)]n SBUs,and 2 is a 3D framework based on[Co_(4)(DCPN)_(2)(μ_(3)-OH)_(2)]SBUs.In addition,the magnetic measurements showed that 1 and 2 have anti ferromagnetic interactions between adjacent Co(II)ions.The slight difference of magnetic properties between 1 and 2 may be attributed to their different structures formed during the assembly process.
