Poly[(?(6)-benzene-1,2,4,5-tetra-carboxyl-ato)bis-(1,10-phenanthroline-?N,N')dimanganese(II)].

ABSTRACT: The title polymeric compound, [Mn(2)(C(10)H(2)O(8))(C(12)H(8)N(2))(2)](n), was obtained by the reaction of manganese(II) chloride tetra-hydrate with benzene-1,2,4,5-tetra-carboxylic acid (H(4)bta) in aqueous solution. Each Mn(2+) ion is coordinated in a distorted octa-hedral geometry by two N atoms from one 1,10-phenanthroline ligand and four O atoms [Mn-O = 2.116?(2)-2.237?(2)?Å] from three bta(4-) ligands, which also act as bridging groups between the Mn(2+) ions.

The title polymeric compound, [Mn(2)(C(10)H(2)O(8))(C(12)H(8)N(2))(2)](n), was obtained by the reaction of manganese(II) chloride tetra-hydrate with benzene-1,2,4,5-tetra-carboxylic acid (H(4)bta) in aqueous solution. Each Mn(2+) ion is coordinated in a distorted octa-hedral geometry by two N atoms from one 1,10-phenanthroline ligand and four O atoms [Mn-O = 2.116 (2)-2.237 (2) Å] from three bta(4-) ligands, which also act as bridging groups between the Mn(2+) ions. ...[more]

Poly[(?-benzene-1,2,4,5-tetra-carboxyl-ato)tetra-silver(I)].

Project description:In the centrosymmetric title compound, [Ag(4)(C(10)H(2)O(8))](n), the benzene ring has irregular bond lengths but remains planar (r.m.s. deviation 0.0002?Å). The Ag-O bond lengths are in the range 2.153?(3)-2.615?(4)?Å. The carboxyl-ate groups are oriented at dihedral angles of 26.4?(5) and 74.9?(4)° to the benzene ring. The coordination behaviour of each carboxyl-ate O atom is different: in one carboxylate, the O atoms are coordinated to a single and two Ag atoms; in the other carboxylate, the O atoms are coordinated to two and three Ag atoms. Non-classical inter-molecular C-H?O hydrogen bonding is present in the crystal structure. The title compound forms a three-dimensional polymeric network due to the coordination of the Ag atoms.

Project description:The asymmetric unit of the title compound, {[MgNa?(C??H?O?)?(H?O)?]·2H?O}(n), contains one octa-hedrally coordin-ated Mg(II) atom (site symmetry 2/m), one octahedrally coordinated Na(I) atom (site symmetry 2) and one half of the dihydrogen benzene-1,2,4,5-tetra-carboxyl-ate (btec) ligand, the second half of the ligand being generated by a twofold rotation axis. The basic framework of the title compound features infinite (-Na-Na-Mg-)(n) chains along [10-1] with the metal cations bridged by the coordinating water molecules. The chains are isolated from each other by ??-bridging btec ligands, which form inter-molecular O-H?O hydrogen bonds to uncoordinated water mol-ecules and the coordinated water mol-ecules of a neighbouring chain. In each btec ligand, there are also intramolecular O-H?O hydrogen bonds.

Project description:In the title complex, {[CaZn(C(10)H(2)O(8))(H(2)O)(2)]·H(2)O}(n), the Zn(II) ion is coordinated by four O atoms from four benzene-1,2,4,5-tetra-carboxyl-ate anions in a distorted tetra-hedral geometry. The Ca(II) ion is eight-coordinated by six O atoms from four benzene-1,2,4,5-tetra-carboxyl-ate anions and by two water mol-ecules in a distorted square-anti-prismatic geometry. The Ca(II) and Zn(II) ions and the lattice water mol-ecule are located on twofold rotation axes; the centroid of the benzene-1,2,4,5-tetra-carboxyl-ate anion is located on a centre of inversion. The ?(8)-bridging mode of the anion results in the formation of a three-dimensional structure with channels extending along [100] in which lattice water mol-ecules are situated. Inter-molecular O-H?O hydrogen bonds involving the coordinating and lattice water mol-ecules as donors and the carboxyl-ate O atoms and lattice water mol-ecules as acceptors are present in the structure.

Project description:The asymmetric unit of the title compound, {(C(5)H(7)N(2))(2)[Ni(C(10)H(2)O(8))(H(2)O)(4)]·2H(2)O}(n), contains an Ni(II) atom, two water mol-ecules of coordination, one half of a benzene-1,2,4,5-tetra-carboxyl-ate (btec) anionic ligand, one 4-amino-pyridinium cation (papy) and an uncoordinated water mol-ecule. The metal center lies on an inversion center and adopts an octa-hedral geometry with the carboxyl-ate groups tilted out of the mean plane formed by the btec. In the crystal, mol-ecules are linked into one-dimensional coordination polymers running along the ac diagonal. The crystal structure is consolidated by N-H?O and O-H?O hydrogen bonds.

Project description:In the title compound, [Co(2)(C(12)H(8)O(12))(C(12)H(8)N(2))(2)](n), each 3,6-dicarb-oxy-cyclo-hexane-1,2,4,5-tetra-carboxyl-ate (H(2)chhc(4-)) anion has crystallographically imposed C(2) symmetry and bridges four six-coordinate Co atoms, generating polymeric chains running along [010]. These chains are further extended into a three-dimensional network via O-H?O hydrogen-bonding inter-actions and inter-chain ?-? stacking inter-actions [centroid-centroid distance = 3.662?(2)?Å].

Project description:In the title compound, [KGd(C(10)H(2)O(8))(H(2)O)(2)](n), the Gd(3+) ion is nine-coordinated by eight O atoms from five individual benzene-1,2,4,5-tetra-carboxyl-ate (btec) ligands and one water mol-ecule, and the K(+) ion is eight-coordinated by six O atoms from five individual btec ligands and two water mol-ecules. In the crystal, the btec half-mol-ecules are completed by crystallographic inversion symmetry. GdO(9) and KO(8) polyhedra are connected, forming layers in the ab plane, which are further inter-connected by ?(8)- or ?(12)-bridging btec ligands, forming a three-dimensional structure.

catena-Poly[[aqua-(1,10-phenanthroline)cadmium(II)]-μ-benzene-1,4-di-carboxyl-ato].

Project description:The title compound, [Cd(C(8)H(4)O(4))(C(12)H(8)N(2))(H(2)O)](n), is a new coordination polymer of benzene-1,4-dicarboxyl-ate with cadmium(II) and 1,10-phenanthroline. The Cd(II) ion is coordinated by two N atoms from the 1,10-phenanthroline mol-ecule, three O atoms from two crystallographically independent benzene-1,4-dicarboxyl-ate ligands and the O atom of a coordinated water mol-ecule, forming a heavily distorted octa-hedron. The 1,10-phenanthroline ligand is approximately planar within 0.073 (4) Å. The two different benzene-1,4-dicarboxyl-ate ligands each coordinate to two Cd(II) ions in bidentate and monodentate modes, forming an infinite zigzag chain. Adjacent chains are packed tightly by strong π-π inter-actions [centroid-centroid distances = 3.851 (2) and 3.859 (2) Å] between the aromatic rings of the benzene-1,4-dicarboxyl-ate ligand and the 1,10-phenanthroline of a neighboring chain, forming a sheet parallel to (011). Different sheets are linked together via O-H⋯O hydrogen bonds between the coordinated water mol-ecules and the O atoms of the carboxyl-ate groups, forming a three-dimensional network.

Poly[diaqua-(?(4)-benzene-1,2,4,5-tetra-carboxyl-ato)[?(2)-1,4-bis-(3-pyridyl-meth-yl)piperazine]dizinc(II)].

Project description:In the title compound, [Zn(2)(C(10)H(2)O(8))(C(16)H(20)N(4))(H(2)O)(2)](n), the Zn(II) atom is in a distorted tetra-hedral environment, being coordinated by one N atom from a 1,4-bis-(3-pyridyl-meth-yl)piperazine (3-bpmp) ligand, two O atoms from two carboxyl-ate groups of the pyromellitate anion and one water mol-ecule. The distortion of the tetrahedral coordination may be ascribed to the hydrogen bonds between the carboxyl-ate groups and the adjacent water mol-ecules. Each Zn(II) atom links to three organic ligands and each pyromellitate ligand coordinates to four Zn(II) atoms, forming a (3,4)-connected infinite three-dimensional framework. O-H?N inter-actions also occur.

Poly[aqua-bis(?(4)-naphthalene-1,4-di-carboxyl-ato)(1,10-phenanthroline-5,6-dione)dimanganese(II)].

Project description:The three-dimensional coordination polymer, [Mn(2)(C(12)H(6)O(4))(2)(C(12)H(6)N(2)O(2))(H(2)O)](n), features a water-coord-inated Mn(II) ion and an N-heterocycle-chelated Mn(II) ion, both in six-coordinate octa-hedral geometries. Of the two rigid dianions, one is bonded to four Mn(II) ions, with each of the O atoms being connected to a different metal ion. The other dianion uses one carboxyl-ate group to chelate to one Mn(II) ion and its other carboxyl-ate group to bind to two Mn(II) ions.

(?-Butane-1,2,3,4-tetra-carboxyl-ato)bis-[triaqua-(1,10-phenanthroline)nickel(II)] hexa-hydrate.

Project description:The asymmetric unit of the title compound, [Ni(2)(C(8)H(6)O(8))(C(12)H(8)N(2))(2)(H(2)O)(6)]·6H(2)O, contains a half of the centrosymmetric dinuclear complex mol-ecule and three uncoordinated water mol-ecules. In the dinuclear mol-ecule, two Ni(II) cations are bridged by the butane-1,2,3,4-tetra-carboxyl-ate (BTC(4-)) anion. Each Ni(II) atom is coordinated by two N atoms from the 1,10-phenanthroline ligand, one O atom from the BTC(4-) anion and three aqua ligands in a distorted octa-hedral geometry. Inter-molecuar O-H?O hydrogen bonds and ?-? stacking inter-ations [centroid-centroid distances = 3.646?(2), 3.781?(2) and 3.642?(2)?Å] consolidate the crystal packing.
