Hydrothermal synthesis, conversion reaction, and crystal structure of 2-D 2-bromo-1,4-benzenedicarboxylate copper(II) complex with 2,2′-bipyridine

A fully deprotonated 2-bromo-1,4-benzenedicarboxylate copper(II) complex, [Cu(bbdc)(2,2'-bipy)](H2O) (bbdc = 2-bromo-1,4-benzenedicarboxylate dianion, 2,2'-bipy = 2,2'-bipyridine), was synthesized under hydrothermal conditions. This compound also can be prepared from the partly deprotonated [Cu(Hbbdc)(2)(2,2'-bipy)] under basic and hydrothermal conditions. The crystal structure consists of infinite chains of [Cu-2(mu(4)-bbdc)](2+) building blocks connected by bis-monodentate bbdc ligands and exhibits an extended 2-D architecture.
