Abstract

The syntheses, IR, molecular structures, and luminescence of [M(HIMDC)(4, 4`-bipyO)0.5(H2O)]n [H3IMDC = 4, 5-imidazoledicarboxylate, 4, 4`-bipyO = 4, 4`-bipyridine-N, N`-dioxide, M = Co (1) and Zn (2)] are reported. The most notable structure feature of 1 and 2 is that the left-handed and right-handed helical chains constructed from 4,5-imidazoledicarboxylate and metal are linked by 4,4`-bipyO to generate infinite 2-D herringbone architectures. 2 exhibits strong fluorescent emission in the solid state at room temperature.
