Two novel interesting d {sup 1} metal coordination polymers, [Zn(H{sub 2}bibzim)(BDC)] {sub n} (1) and [Cd(H{sub 2}bibzim)(BDC)] {sub n} (2) [H{sub 2}bibzim=2,2'-bibenzimidazole, BDC=1,4-benzenedicarboxylate] have been synthesized under solvothermal conditions and structurally characterized. Both 1 and 2 are constructed from infinite neutral zigzag-like one-dimensional (1D) chains. The {pi}-{pi} interactions and interchain hydrogen-bonding interactions further extend the 1D arrangement to generate a 3D supramolecular architecture for 1 and 2. Both complexes have high thermal stability and display strong blue fluorescent emissions in the solid state upon photo-excitation at 365 nm at room temperature. They are the first two examples that 2,2'-bibenzimidazole has been introduced into the d {sup 1} coordination polymeric framework.
