Abstract

A new zinc(II)?barium(II) bimetallic coordination polymer, [BaZn2(TMA)2(Im)2] (1), has been synthesized by hydrothermal reaction of zinc(II) acetate, barium(II) acetate, trimesic acid (H3TMA), and imidazole (Im), and was characterized by single-crystal X-ray diffraction, powder X-ray diffraction, elemental analysis, thermogravimetric analysis, and infrared and photoluminescence spectroscopy. Single crystal X-ray analysis reveals that compound 1 crystallizes in the centrosymmetric triclinic system with space group P-1 and features a dense three-dimensional framework. Compound 1 exhibits intense blue fluorescent emission in the solid state at room temperature and the framework shows remarkable thermal stability up to 460°C.

Keywords: coordination polymers, crystal structure, photoluminescence, cobalt(II), barium(II), zinc(II)
