摘　　要：Three coordination polymers([Zn(H_2biim)_2(H_2O)_2]_2·2(HO-BDC)·x(H_2O)(1)[Cd(H_2biim)_2(H_2O)_2]_2·2(HO-BDC)·x(H_2O)(2) and [Co(HO-BDC)(bbi)]n(3)) are obtained by using synthetic-condition strategy in the mixed-ligand system 5-hydroxyisophthalic acid(OH-BDC)together with bisimidazole ligands(2,2?-biimidazole(H2 biim) and 1,1?-(1,4-butanediyl)bis(imidazole)(bbi)). The structure determination reveals that complexes 1 and 2 are zero-dimensional(0 D) structures, and complex 3 is a dinuclear two-dimensional(2D) layer structure. They are all 3D supramolecular networks. The comparisons of the synthetic-condition effects and structure differences among 1 ～3 and our previous work complexes 4([Co_2(HO-BDC)_2(bbi)_2]·H_2O) and 5([Zn(HO-BDC)(bbi)]) have been discussed in detail. Furthermore, the luminescent properties and thermal stabilities of compounds 1～3 in the solid state have been studied.
