Project description:In the polymeric title compound, {[Mn(2)(SO(4))(2)(C(30)H(36)N(6))(H(2)O)(2)]·6H(2)O}(n), the two Mn(2+) ions are bridged by two sulfate anions to form dinuclear complexes, and these dinuclear species are linked by the hexa-dentate ligand N,N,N',N'-tetra-kis(2-pyridylmeth-yl)hexane-1,6-diamine (tphn), forming a one-dimensional chain structure running in the [101] direction. The repeat unit of the polymer, Mn(2)(SO(4))(2)(H(2)O)(2)(tphn), is disposed about a twofold axis passing through the centre of the dinuclear unit. The coordination geometry around the Mn centre is distorted octa-hedral. Two methylene groups are each disordered equally over two positions.

Di-methyl-ammonium tetra-aqua-(hydrogen-sulfato)-sulfato-cuprate(II).

Project description:In the title salt, [(CH3)2NH2][Cu(HSO4)(SO4)(H2O)4], one type of cation and anion is present in the asymmetric unit. The Cu(II) atom in the complex anion, [Cu(HSO4)(SO4)(H2O)4](-), has a tetra-gonal bipyramidal [4 + 2] coordination caused by a Jahn-Teller distortion, with the aqua ligands in equatorial and two O atoms of tetra-hedral HSO4 and SO4 units in apical positions. Both types of ions form sheets parallel to (010). The inter-connection within and between the sheets is reinforced by O-H?O and N-H?O hydrogen bonds, respectively, involving the water mol-ecules, the two types of sulfate anions and the ammonium groups.

catena-Poly[[[aqua-copper(II)]-bis-[?-N,N'-bis-(pyridin-4-yl)isophthalamide]-[aqua-copper(II)]-di-?-sulfato] dimethyl-formamide disolvate].

Project description:In the title coordination polymer, {[Cu(SO4)(C18H14N4O2)(H2O)]·C3H7NO} n , the Cu(II) ion is coordinated by two N atoms of two briding N,N'-bis-(pyridin-4-yl)isophthalamide ligands, two O atoms of two bridging SO4(2-) anions and a water mol-ecule, giving a distorted CuN2O3 square-pyramidal geometry. The whole repeating mol-ecular unit is generated by inversion symmetry. This leads to the formation of a looped-chain one-dimensional coordination polymer propagating along [110]. The dimethyl-formamide (DMF) mol-ecules are linked to the chains via O-H?O hydrogen bonds. The chains are linked via N-H?O hydrogen bonds, forming two-dimensional networks parallel to (001). There are also a number of C-H?O inter-actions present and a parallel slipped ?-? inter-action. The latter involves inversion-related pyridine rings with a centroid-centroid distance of 3.594?(2)?Å [normal distance = 3.3338?(13) and slippage = 1.341?Å]. These inter-actions lead to the formation of a three-dimensional structure.

Monoclinic polymorph of poly[[di-?-aqua-triaquadi-?-oxalato-barium(II)-copper(II)] monohydrate].

Project description:A monoclinic polymorph of the title compound, {[BaCu(C(2)O(4))(2)(H(2)O)(5)]·H(2)O}(n), is reported. The structure is best described as a coordination polymer where the Cu(II) and Ba(II) centers are coordinated by five and nine O atoms, respectively, in capped quadratic antiprismatic and tetragonal pyramidal geometries. The polymerization arises due to the presence of bridging mono- and bidentate oxalate ligands as well as bridging water mol-ecules. The crystal structure is consolidated by a three-dimensional network of hydrogen bonding.

(Di-2-pyridyl-amine)-(methanol)sulfato-copper(II).

Project description:The title complex, [Cu(SO(4))(C(10)H(9)N(3))(CH(3)OH)], is a mononuclear species with the Cu(II) ion in a Jahn-Teller-distorted '4 + 1' square-pyramidal geometry. The basal plane is defined by the pyridyl N-atom donors of the bipyridyl-amine (bpa) ligand and two O-atom donors of the sulfate ligand. The coordination geometry is completed by the axial coordination of a methanol O-atom donor. The axial bond length displays the usual elongation: Cu-O(axial) = 2.168?(2), Cu-O(basal) = 2.016?(2) (average) and Cu-N(basal) = 1.951?(3)?Å (average). In the crystal structure, the complex mol-ecules are linked through N-H?O and O-H?O hydrogen bonds into chains along [100].

Poly[tetra-deca-aqua-tetra-kis-(?(3)-1H-imidazole-4,5-dicarboxyl-ato)tetra-?(3)-sulfato-cobalt(II)hexa-gadolinium(III)].

Project description:The asymmetric unit of the title compound, [CoGd(6)(C(5)H(2)N(2)O(4))(4)(SO(4))(6)(H(2)O)(14)](n), contains a Co(II) ion (site symmetry [Formula: see text]), three Gd(III) ions, two imidazole-4,5-dicarboxyl-ate ligands, three SO(4) (2-) anions, and seven coordinated water mol-ecules. The Co(II) ion is six-coordinated by two O atoms from water mol-ecules, two O atoms and two N atoms from two imidazole-4,5-dicarboxyl-ate ligands, giving a slightly distorted octa-hedral geometry. The Gd(III) ions exhibit three types of coordination environments. One Gd ion is eight-coordinated in a bicapped trigonal-prismatic geometry by four O atoms from two imidazole-4,5-dicarboxyl-ate ligands, two O atoms from two SO(4) (2-) anions and two coordinated water mol-ecules. The other Gd ions are nine-coordinated in a tricapped trigonal-prismatic geometry; one of these Gd ions is bonded to four O atoms from two imidazole-4,5-dicarboxyl-ate ligands, three O atoms from three SO(4) (2-) anions and two water O atoms and the other Gd ion is coordinated by one O atom and one N atom from one imidazole-4, 5-dicarboxyl-ate ligand, five O atoms from three SO(4) (2-) anions as well as two coordinated water mol-ecules. These metal coordination units are connected by bridging imidazole-4,5-dicarboxyl-ate and sulfate ligands, generating a three-dimensional network. The crystal structure is further stabilized by N-H?O, O-H?O, and C-H?O hydrogen-bonding inter-actions between water mol-ecules, SO(4) (2-) anions, and imidazole-4,5-dicarboxyl-ate ligands.

Poly[hexa-aqua-(?9-cyclo-hexane-1,2,3,4,5,6-hexa-carboxyl-ato)trimanganese(II)].

Project description:The asymmetric unit of the title compound, [Mn3(C12H6O12)(H2O)6] n , comprises one Mn(II) ion, one third of a cyclo-hexane-1,2,3,4,5,6-hexa-carboxyl-ate anion and two aqua ligands. The anion is completed by application of a -3 axis. The Mn(II) ion is six-coordinated by six O atoms from two aqua ligands and three different cyclo-hexa-carboxyl-ate anions in an octa-hedral geometry. The six carboxyl-ate groups adopt a bridging bidentate mode to ligate the Mn(II) ions. Thus, each cyclo-hexane-1,2,3,4,5,6-hexa-carboxyl-ate anion adopts a ?9-connected mode, ligating nine different Mn(II) ions and forming a three-dimensional framework. In the framework, there are strong O-H?O hydrogen-bonding inter-actions, which further stabilize the crystal structure.
