摘要：

Two novel interesting d(10) metal coordination polymers, [Zn(H(2)bibzim)(BDC)](n) (1) and [Cd(H(2)bibzim)(BDC)](n) (2) [H(2)bibzim = 2,2'-bibenzimidazole, BDC = 1,4-benzenedicarboxylate] have been synthesized under solvothermal conditions and structurally characterized. Both I and 2 are constructed from infinite neutral zigzag-like one-dimensional (ID) 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(10) coordination polymeric framework. (c) 2005 Elsevier Inc. All rights reserved.
