Poly[diaqua-?(3)-4-nitro-phthalato-copper(II)].

ABSTRACT: In the title complex, [Cu(C(8)H(3)NO(6))(H(2)O)(2)](n), the two carboxyl-ate groups of the 4-nitro-phthalate 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 carboxyl-ate groups of three 4-nitro-phthalate ligands and two O atoms of the non-equivalent coordinated water mol-ecules. 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 inter-layer hydrogen bonding involving an O atom of a nitro group. The whole three-dimensional structure is further maintained and stabilized by intra-layer hydrogen bonds between the O atoms of the carboxyl-ate groups and the coordinated water mol-ecules.

Bis(?-4-nitro-phthalato)bis-[diaqua-(1,10-phenanthroline)manganese(II)].

Project description:In the title compound, [Mn(2)(C(8)H(3)NO(6))(2)(C(12)H(8)N(2))(2)(H(2)O)(4)], the Mn(II) atom in the centrosymmetric binuclear unit has a distorted octa-hedral geometry and is coordinated by a chelating 1,10-phenanthroline ligand, two monodentate carboxyl-ate anions from two 4-nitro-phthalates and two coordinated water mol-ecules. The two Mn(II) ions in the mol-ecule are bridged by two 4-nitro-phthalate anions, both in a bis-monodentate mode, which finally leads to the formation of the binuclear unit. Intra-molecular O-H?O hydrogen bonds between the coordinated and uncoordinated O atoms of one monodentate carboxyl-ate group and the corresponding coordinated water mol-ecules result in an eight-membered and two six-membered rings. In the crystal structure, inter-molecular O-H?O hydrogen bonds link the dinuclear mol-ecules into supra-molecular chains propagating parallel to [100].

Project description:In the title layer complex, {[Ni(C(8)H(4)O(4))(C(10)H(8)N(2))(H(2)O)(2)]·2H(2)O}(n), the Ni atom has a distorted octa-hedral environment, defined by the phthalate and 4,4'-bipyridyl ligands which link the Ni atoms, forming a square lattice in the bc plane. This extends into a three-dimensional supra-molecular network through O-H?O hydrogen-bonding inter-actions. The Ni atom lies on, and both ligands are bis-ected by, a crystallographic twofold axis.

Project description:The title complex, [Cu(C(7)H(3)NO(4))(H(2)O)(2)](n), was prepared under hydro-thermal reaction conditions.
