Three structurally novel compounds were synthesized by self-assembly using the ligand precursor HECTV(5,6,12,13,19,20-hexaimidazol-ethoxycyclohexene)with Zn(CH3COO)2·4H2O,Cd(CH3COO)2·4H2O,H2bdc(isophthalic acid),and OH-H2bdc(5-hydroxyisophthalic acid)by optimizing reaction temperature,solvent,and other factors.[Zn6(HECTV)(bdc)5(HCOO)2]·4DMF·2H2O(1),[Cd3(HECTV)(bdc)3]·6.5H2O(2),[Cd3(HECTV)(OH bdc)2(H2O)2]·DMF·2H2O(3).Compounds 1 to 3 exhibited different two-dimensional or three-dimensional structures.The differences in organic carboxylic acid ligands led to significant structural changes in the synthesized complexes.In addition,the luminescent properties of compounds 1 to 3 were investigated.
