Crystal structure and luminescence properties of a new dinuclear bismuth(III) coordination polymer containing three types of ligands

A new dinuclear bismuth(III) coordination polymer {[Bi(H2O)](2)(C7H3NO4)(2)(C12H8N2)(2)(N-3)(2)center dot 2H(2)O}(n) (1) containing three types of ligands has been synthesized using a solvothermal method and characterized by infrared (IR) spectroscopy, energy-dispersive X-ray spectroscopy, and X-ray single-crystal structural analysis. The compound can be viewed as a three-dimensional supramolecular network that is constructed by Bi3+ cations, N-3(-) anions, pyridine-2,5-dicarboxylate (2,5-pdc(2-)), and 1,10-phenanthroline (phen) ligands. Moreover, the luminescence properties, quantum yield, luminescence decay, and thermal stabilities of 1 were also investigated.
