Bis[?-4-(4-carb-oxy-phen-oxy)phthalato]bis-[triaqua-cobalt(II)].

ABSTRACT: The dinuclear title complex, [Co(2)(C(15)H(8)O(7))(2)(H(2)O)(6)], lies across an inversion center. The unique Co(II) ion is coordinated in a slightly distorted octa-hedral coordination geometry by two O atoms from a chelating 4-(carb-oxy-phen-oxy)phthalate ligand, three water O atoms and a further O atom from a bridging carboxyl-ate group of a symmetry-related 4-(carb-oxy-phen-oxy)phthalate ligand. In the crystal, O-H?O hydrogen bonds link the mol-ecules into a three-dimensional network.

catena-Poly[[[triaqua-[3-(4-carb-oxy-phen-oxy)phthalato-κO(2)]manganese(II)]-μ-4,4'-bipyridine-κ(2)N:N'] 4,4'-bipyridine monosolvate dihydrate].

Project description:In the title compound, {[Mn(C(15)H(8)O(7))(C(10)H(8)N(2))(H(2)O)(3)]·C(10)H(8)N(2)·2H(2)O}(n), the bridging mode of the coordinating 4,4'-bipyridine ligands leads to the formation of polymeric zigzag chains parallel to [0-11]. The chains are separated by 4,4'-bipyridine and water solvent mol-ecules. Within a chain, the Mn(II) atom is six-coordinated by two N atoms of the bridging 4,4'-bipyridine ligands, three water O atoms and one carboxyl-ate O atom of a single deprotonated 3-(4-carb-oxy-phen-oxy)phthalic acid ligand. Both coordinating and solvent 4,4'-bipyridine mol-ecules are situated on centres of inversion. An intricate network of O-H⋯O and O-H⋯N hydrogen bonds involving the carb-oxy group, the coordinating water mol-ecules and the two types of solvent mol-ecules leads to the formation of a three-dimensional network.

(?-4,4'-Bipyridine-?N:N')bis-[triaqua-(4,4'-bipyridine-?N)(3-nitro-phthalato-?O)cobalt(II)].

Project description:The title binuclear complex, [Co(2)(C(8)H(3)NO(6))(2)(C(10)H(8)N(2))(3)(H(2)O)(6)], has been synthesized hydro-thermally from 3-nitro-phthalic acid (H(2)NPA), Co(NO(3))(2)·6H(2)O and 4,4'-bipyridine (4,4'-bipy). The mol-ecule of the complex occupies a special position on an inversion centre. The Co(II) atom has a slightly distorted octa-hedral environment formed by two N atoms from two 4,4'-bipy ligands, one carboxyl-ate O atom from NPA, and three O atoms of water mol-ecules. An extensive O-H?O and N-H?O hydrogen-bonding system links mol-ecules of the complex into a three-dimensional network.

Triaqua-(3-carb-oxy-5-sulfonatobenzoato-κO)(1,10-phenanthroline-κN,N')cobalt(II) monohydrate.

Project description:In the title compound, [Co(C(8)H(4)O(7)S)(C(12)H(8)N(2))(H(2)O)(3)]·H(2)O, the Co(II) cation is coordinated by one sulfoisophthalate dianion, one bidentate phenathroline (phen) mol-ecule and three water mol-ecules in a distorted cis-CoN(2)O(4) octa-hedral geometry. In the crystal structure, aromatic π-π stacking occurs [centroid-centroid distances 3.7630 (14) and 3.7269 (15) Å], as well as an extensive O-H⋯O and C-H⋯O hydrogen-bonding network.

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].

Bis[2,6-bis-(2-meth-oxy-phen-yl)pyridinium] di-μ-bromido-bis-[dibromidocuprate(II)].

Project description:The title salt, (C(19)H(18)NO(2))(2)[Cu(2)Br(6)], was obtained from an attempt to synthesize the copper(II) complex of 2,6-bis-(2-meth-oxy-phen-yl)pyridine (L) from a reaction between CuBr(2) and one equivalent of L in CH(2)Cl(2) at room temperature. The resulting compound is the salt of the 2,6-bis-(2-meth-oxy-phen-yl)pyridinium cation and 0.5 equivalents of a hexa-bromido-dicuprate(II) dianion. Both meth-oxy groups of the cationic pyridinium moiety are directed towards the N atom of the pyridine ring as a result of intra-molecular N-H⋯O hydrogen bonds. The centrosymmetric hexabromidodicuprate dianion possesses a distorted tetra-hedral geometry at the copper ion. The Cu-Br bond lengths are 2.3385 (7) and 2.3304 (7) Å for the terminal bromides, whereas the bond length between the Cu atom and two bridging bromides is slightly longer [2.4451 (6) Å].

Poly[[diaqua-bis[μ-(2,4-dichloro-phen-oxy)acetato]calcium(II)] monohydrate].

Project description:In the title coordination polymer, {[Ca(C(8)H(5)Cl(2)O(3))(2)(H(2)O)(2)]·H(2)O}(n), the Ca(II) atom is eight-coordinated by six O atoms from four different (2,4-dichloro-phen-oxy)acetate ligands and two water mol-ecules, and displays a distorted square-anti-prismatic coordination geometry. The compound forms an infinite zigzag chain through connection of the metal centers by (2,4-dichlorphen-oxy)acetate ligands and hydrogen bonding of coordinated and inter-stitial water mol-ecules. These chains are further hydrogen bonded with neighboring chains, forming a supra-molecular network.

Project description:The title compound, [Co(3)Na(2)(C(7)H(2)ClNO(4))(4)(H(2)O)(12)][Co(C(7)H(2)ClNO(4))(H(2)O)(3)](2)·6H(2)O, consists of a centrosymmetric dimer of [Co(II)(dipicCl)(2)](2-) complex dianions [dipicCl is 4-chloro-pyridine-2,6-dicarboxyl-ate] bridged by an [Na(2)Co(II)(H(2)O)(12)](4+) tetra-cationic cluster, two independent [Co(dipicCl)(H(2)O)(3)] complexes, and six water mol-ecules of crystallization. The metals are all six-coordinate with distorted octahedral geometries. The [Co(II)(dipicCl)(H(2)O)(3)] complexes are neutral, with one tridentate ligand and three water molecules. The [Co(II)(dipicCl)(2)](2-) complexes each have two tridentate ligands. The [Na(2)Co(II)(H(2)O)(12)](4+) cluster has a central Co(II) ion which is coordinated to six water molecules and lies on a crystallographic inversion center. Four of the water molecules bridge to two sodium ions, each of which have three other water molecules coordinated along with an O atom from the [Co(II)(dipicCl)(2)](2-) complex. In the crystal structure, the various units are linked by O-H⋯O hydrogen bonds, forming a three-dimensional network. Two water molecules are disordered equally over two positions.
