Two d10 metal complexes[Zn(bmib)(HCOO)2]·3H2O(1)and[Cd(bmib)0.5(tdc)(DMF)(H2O)](2)(bmib=1,4-bis(2-bethyl-1H-imidazol-1-yl)benzene,H2tdc=2,5-thiophenedicarboxylic acid)were synthesized by solvent thermal conditions.The synthesis conditions of the two complexes were the similar except for different metal salts.However,structural analysis revealed that H2tdc in complex 1 did not participate in coordination.Structure of complex 1 was a 1D Z-shaped chain formed by bmib ligand and Zn2+.Complex 2 is a 1D ladder chain composed of bmib,H2tdc and Cd2+.Results show that metal ions play an important role in the structure of complexes.Thermogravimetric analysis showed that the two complexes had good thermal stability.Solid fluorescence properties indicated that complexes 1 and 2 had blue fluorescence with the strongest fluorescence emission peak at 460 nm and 470 nm,respectively,which have potential value as luminescent materials.
