Controlled hydrothermal synthesis of copper(II or I,II) coordination polymers via pH-dependent in situ metal/ligand redox reactions

Three new coordination polymers synthesized from a mixture of Cu(NO3)(2), NaOH, 4,4'-bipyridine (4,4'-bpy) and 1,2,3-benzenetricarboxylic acid (1,2,3-btcH(3)) illustrate the pH dependence of in situ metal/ligand redox reactions.
