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(μ-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.

Poly[diaqua-(μ(3)-pyridine-3,5-dicarboxyl-ato-κN:O:O)copper(II)].

Project description:The title complex, [Cu(C(7)H(3)NO(4))(H(2)O)(2)](n), was prepared under hydro-thermal reaction conditions. In the crystal structure, the Cu(II) cation is located on a twofold rotation axis and is coordinated by two carboxyl-ate O atoms and one N atom from three pyridine-3,5-dicarboxyl-ate (PDA) anions and two water mol-ecules with a distorted trigonal-bipyramidal geometry. The tridentate PDA anion is also located on the twofold rotation axis and bridges the Cu(II) cations to form a two-dimensional polymeric layer. O-H⋯O hydrogen bonding between layers links the two-dimensional layers into a three-dimensional supra-molecular framework.

Crystal structure of catena-poly[[copper(II)-μ2-salicylato-[diaqua-copper(II)]-μ2-salicylato] dihydrate].

Project description:The title compound, {[Cu2(C7H4O3)2(H2O)2]·2H2O} n , contains two copper(II) cations in special positions (one on a twofold rotation axis and one on an inversion centre) and the the salicylate ligand in its dianionic form. By four- and six-coordinate metal coordination, chains are formed parallel to [001], which are extended by O-H⋯O hydrogen bonding into sheets extending parallel to (100). These sheets are weakly connected by O-H⋯O hydrogen bonding via the non-coordinating lattice water mol-ecules into a three-dimensional network.

Poly[diaqua-di-μ(4)-citrato-trizinc(II)].

Project description:The title compound, [Zn(3)(C(6)H(5)O(7))(2)(H(2)O)(2)](n), is a polymer in which the repeating unit contains three zinc atoms, two hepta-dentate Hcit ligands (Hcit = citric acid trianion) and two coordinated water mol-ecules, only half of which are independent due to one of the metal atoms lying on a centre of symmetry. The two independent cations both exhibit an octa-hedral geometry, but the way in which they are coordinate are different; while the Zn atom in a general position is bound to three Hcit ligands and one water mol-ecule, the one at the centre of symmetry is coordinated by six O atoms from two symmetry-related Hcit ligands through the (protonated) hydroxyl and carboxyl-ate groups. The three carboxyl-ate groups coordinate to the Zn centres in three different ways, viz. chelating, bridging and a mixture of both, in an unusual coordination mode for citrate. The result is a two-dimensional structure parallel to (010), built up by a square-grid motif. Intermolecular O-H⋯O hydrogen bonds are present in the crystal structure.

Project description:In the title compound, [Zn(C(4)H(4)O(4))(C(5)H(5)N)(2)(H(2)O)(2)](n), the Zn(II) ion (site symmetry ) is coordinated in an octahedral geometry by two pyridine mol-ecules, two water mol-ecules and two bridging centrosymmetric O-monodentate succinate dianions to create one-dimensional polymeric chains. The chains are cross-linked by O-H⋯O hydrogen bonds, forming sheets.

Poly[tetra-μ-aqua-diaqua-tetra-kis-[μ-(E)-2-nitro-cinnamato]tetra-rubidium].

Project description:In the structure of the title compound, [Rb(4)(C(9)H(6)NO(4))(4)(H(2)O)(6)](n), the asymmetric unit comprises four rubidium cations, two of which have an RbO(7) coordination polyhedron with a monocapped distorted octa-hedral stereochemistry and two of which have a distorted RbO(6) octa-hedral coordination. The bonding about both the seven-coordinate cations is similar, comprising one monodentate water mol-ecule together with three bridging water mol-ecules and three carboxyl-ate O-atom donors, two of which are bridging. The environments around the six-coordinate cations are also similar, comprising a monodentate nitro O-atom donor, a bridging water mol-ecule and four bridging carboxyl-ate O-atom donors [overall Rb-O range = 2.849 (2)-3.190 (2) Å]. The coordination leads to a two-dimensional polymeric structure extending parallel to (001), which is stabilized by inter-layer water O-H⋯O hydrogen-bonding associations to water, carboxyl and nitro O-atom acceptors, together with weak inter-ring π-π inter-actions [minimum ring centroid-centroid separation = 3.5319 (19) Å].

Project description:In the title complex, [Zn(C(8)H(3)NO(6))(C(4)H(6)N(2))(2)](n), the carboxyl-ate groups of the 3-nitro-phthalate dianion ligand coordinate the Zn(II) ion in a bis-monodentate mode. The Zn(II) ion shows distorted tetra-hedral coordination as it is bonded to two O atoms from the carboxyl-ate groups of symmetry-related 3-nitro-phthalate anions and two N atoms of two independent 1-methyl-imidazole mol-ecules. The bridging 3-nitro-phthalate ligand allows the formation of one-dimensional chains in the c direction. The crystal structure is further stabilized by weak inter-molecular C-H⋯O hydrogen bonds.

Poly[[diaqua-μ(4)-tartrato-μ(2)-tartrato-dimanganese(II)] dihydrate].

Project description:In the title compound, {[Mn(C(4)H(4)O(6))(H(2)O)]·H(2)O}(n), the Mn(2+) ion is connected to three different tartrate anions and a water mol-ecule, resulting in a distorted MnO(6) octa-hedral geometry. There are two tartrate half-anions in the asymmetric unit, both of which are completed by crystallographic twofold rotation symmetry. The tartrate dianions bridge the Mn(2+) ions to form a wave-like infinite layer. A series of O-H⋯O hydrogen bonds link the layers into a three-dimensional network.
