Metal complexes synthesis and properties

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. Crystal data are orthorhombic, space group Pbcn, a = 11.242(3) Å, b = 16.963(4) Å, c = 13.898(4) Å, Z = 4 for 1 and monoclinic, space group C2/c, a = 18.887(4) Å, b = 10.761(2) Å, c = 14.488(3) Å, β = 126.100(3)°, Z = 4 for 2.
