Three novel coordination polymers, namely, [Zn2(betc)(L1)H(H2O)]·2H2O (1), [Zn2(btec)(L2)2] (2) and [Zn5(btec)2(L3)1.5(OH)2]·2H2O (3) (L1 = 3,5-di(1H-imidazol-1-yl)benzoate, L2 = 1,3-bis((1H-1,2,4-triazol-1-yl)methyl)benzene and L3 = 1,3-di(1H-1,2,4-triazol-1-yl)propane), have been hydrothermally synthesized. Compound 1 shows a three dimensional (3D) framework with fsc-3,5-P4/mbm topology. Compound 2 reveals a 3D pillar-layered framework with the presence of 3-fold left- and right-handed helical chains. Compound 3 also exhibits a 3D framework based on 1D zinc chains. In addition, the luminescent properties for 1–3 have also been investigated.
