Hydrothermal synthesis and novel two-dimensional architecture with fluorescent properties constructed using 2-bromo-1,4-benzenedicarboxylate

A novel two-dimensional complex, [Cu(bbdc)(phen)]·(H₂O)(bbdc = 2-bromo-1,4-benzenedicarboxylate dianion; phen = 1,10-phenanthroline), has been synthesized and structurally characterized by single crystal X-ray analysis. The crystal structure consists of infinite chains of [Cu₂(₄-bbdc)]²⁺ units connected by bis-monodentate bbdc ligands, the coordination mode of which [₄-bbdc] is very rare in the phenyldicarboxylate complexes. The substituent group of bbdc is believed to be the growth key of this coordination network.
