Poly[diaqua-μ(3)-4-nitrophthalato-copper(II)]
In the title complex, [Cu(C(8)H(3)NO(6))(H(2)O)(2)](n), the two carboxylate groups of the 4-nitrophthalate dianion ligands have monodentate and 1,3-bridging bonding modes, respectively. The Cu atom shows an approximate square-pyramidal coordination as it is bonded to O atoms from the carboxylate...

Sumario: | In the title complex, [Cu(C(8)H(3)NO(6))(H(2)O)(2)](n), the two carboxylate groups of the 4-nitrophthalate dianion ligands have monodentate and 1,3-bridging bonding modes, respectively. The Cu atom shows an approximate square-pyramidal coordination as it is bonded to O atoms from the carboxylate groups of three 4-nitrophthalate ligands and two O atoms of the non-equivalent coordinated water molecules. Other Cu atoms in the coordination polymer are connected into a two-dimensional layer in the ab plane. The layers are aggregated to a three-dimensional structure through interlayer hydrogen bonding involving an O atom of a nitro group. The whole three-dimensional structure is further maintained and stabilized by intralayer hydrogen bonds between the O atoms of the carboxylate groups and the coordinated water molecules. |
