Construction of a Three-fold Parallel Interpenetration Network and Bilayer Structure Based on Copper(II) and Trimesic Acid

Solvothermal reactions of Cu(NO3)2·3H2O with trimesic acid (H3BTC) at different pH conditions yield two coordination
polymers of [Cu3(BTC)2(H2O)3(NH3)4]n·2nH2O (1) and [Cu4(BTC)2(OH)2(H2O)2(NH3)4]n (2). Crystal structural analysis reveals
that complex 1 exhibits a three-fold parallel interpenetration network and complex 2 shows a two-dimensional bilayer structure.
