Abstract: 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.
