Catena-Poly[[[triaqua-manganese(II)]-?-4,4'-bipyridine-?N:N'-[triaqua-manganese(II)]-?-pyrimidine-4,6-dicarboxyl-ato-?N,O:N,O] sulfate trihydrate].

ABSTRACT: The two independent Mn(II) ions in the polymeric title compound, {[Mn(2)(C(6)H(2)N(2)O(4))(C(10)H(8)N(2))(H(2)O)(6)]SO(4)·3H(2)O}, exhibit distorted MnN(2)O(4) octa-hedral coordination geometries, with the pyrimidine-4,6-dicarboxyl-ate (pmdc) ligand acting in the bis-chelating ?-(?O,?N:?O',?N') bridging mode and the 4,4'-bipyridine (bpy) ligand in the ?-(?N:?N') bridging mode. The remaining coordination sites are occupied by O atoms of water mol-ecules. As a consequence, cationic chains of [Mn(2)(?-pmdc)(?-4,4'-bpy)(H(2)O)(6)](2+) are generated, which extend approximately along the a axis. Sulfate counter-anions and three uncoordinated water mol-ecules complete the structure, which is stabilized by multiple O-H?O hydrogen-bonding inter-actions between the structural units.

Poly[(μ-4,4'-bipyridine)(μ-naphthalene-1,4-dicarboxyl-ato)manganese(II)].

Project description:In the crystal structure of the title compound, [Mn(C(12)H(6)O(4))(C(10)H(8)N(2))](n), the Mn atoms are each coordinated by four O atoms of naphthalene-1,4-dicarboxyl-ate anions and two N atoms of two symmetry-related 4,4'-bipyridine ligands within a strongly distorted octa-hedra. Two of the O atoms originate from one naphthalene-1,4-dicarboxyl-ate anion, whereas the remaining two O atoms derive from two symmetry-equivalent naphthalene-1,4-dicarboxyl-ate anions. Two Mn atoms are connected via the anions into dimers, which are further linked by the anions and the N-donor ligands into a three-dimensional coordination network.

Project description:The title compound, {[Cu(C(12)H(6)N(2)O(4))(H(2)O)(3)]·H(2)O}(n), was synthesized under hydro-thermal conditions. The Cu(2+) ion is six-coordinated by three water O atoms, and two N atoms and one O atom of the 2,2'-bipyridine-3,3'-dicarboxyl-ate bridging ligand in a sligthly distorted octa-hedral environment. The 2,2-bipyridine-3,3'-dicarboxyl-ate bridges link the Cu(2+) ions into chains along the b-axis direction. These chains are further linked by O-H?O hydrogen bonds involving the water solvent mol-ecules, forming a three-dimensional framework.

catena-Poly[[[tetra-aqua-cobalt(II)]-μ-4,4'-bipyridine-κN:N'] pyridine-3,5-dicarboxyl-ate trihydrate].

Project description:The crystal structure of the title compound, {[Co(C(10)H(8)N(2))(H(2)O)(4)](C(7)H(3)NO(4))·3H(2)O}(n), consists of Co(II) polymeric complex cations, uncoordinated pyridine-3,5-dicarboxyl-ate anions and lattice water mol-ecules. The Co(II) cation is coordinated by two N atoms from two 4,4'-bipyridine ligands and four water mol-ecules in a distorted octa-hedral geometry. The 4,4'-bipyridine ligands bridge Co cations, forming a polymeric chain running along the b axis. The two pyridine rings of the 4,4'-biyridine are twisted to each other by a dihedral angle of 8.95 (9)°. Extensive O-H⋯O hydrogen bonding network is present in the crystal structure.

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.

catena-Poly[[[triaqua-copper(II)]-μ(2)-pyrazine-2,3-dicarboxyl-ato] monohydrate].

Project description:The Cu atom in the title complex, {[Cu(C(6)H(2)N(2)O(4))(H(2)O)(3)]·H(2)O}(n) or {[Cu(L)(H(2)O)(3)]·H(2)O}(n) (L is pyrazine-2,3-dicarbox-yl-ate), displays octa-hedral coordination formed by the ligand L and three coordinated water mol-ecules. The ligand L is tridentate, with one N atom of the pyrazine ring and one O atom of one carboxyl-ate group forming a chelate ring, whereas one O atom from the second carboxyl-ate group is coordinated to another Cu atom. The ligand L links mol-ecules to form an infinite chain parallel to the [101] direction. The chains are further linked through O-H⋯O and O-H⋯N hydrogen bonds involving the water mol-ecules to build up a three-dimensional network.

Project description:In the title compound, [Zn(C(4)HN(3)O(4))(H(2)O)(3)](n), each Zn(II) atom adopts a distorted octa-hedral coordination geometry, being surrounded by one chelating and one monodentate 1H-1,2,4-triazole-3,5-dicarboxyl-ate ligand and three water mol-ecules. Adjacent Zn(II) cations are linked by a 1H-1,2,4-triazole-3,5-dicarboxyl-ate ligand in a μ(2),κ(3) fashion to form a chain running along the c axis. The crystal packing is stabilized by N-H⋯O, O-H⋯N and O-H⋯O hydrogen bonds.

Poly[(?-4,4'-bipyridine)(?-naph-tha-lene-1,4-dicarboxyl-ato)iron(II)].

Project description:The asymmetric unit of the title compound, [Fe(C(12)H(6)O(4))(C(10)H(8)N(2))], consists of two independent Fe(II) atoms, two naphthalene-1,4-dicarboxyl-ate anions and two 4,4'-bipyridine ligands. The Fe(II) atoms are each coordinated by four O atoms of the naphthalene-1,4-dicarboxyl-ate anions and two N atoms of the 4,4'-bipyridine ligands within a distorted octa-hedron. Two Fe(II) atoms are bridged via the carboxyl-ate groups of two symmetry-related anions into dimers, which are further connected into chains. These chains are linked by additional anions into layers that are finally connected by the 4,4'-bipyridine ligands into a three-dimensional coordination network.

catena-Poly[[(2,2'-bipyridine)-manganese(II)]-?(3)-4,4'-sulfonyl-dibenzoato].

Project description:In the title compound, [Mn(C(14)H(8)O(6)S)(C(10)H(8)N(2))](n), the Mn(II) ion is coordinated by four O atoms from three 4,4'-sulfonyl-dibenzoate (sdba) ligands and two N atoms from one 2,2'-bipyridine (2,2'-bipy) ligand in a distorted octa-hedral geometry. The manganese atoms are alternately bridged either by two sdba ligands, with an Mn?Mn separation of 12.284?(1)?Å, or by two carboxyl-ate groups from two sdba ligands, with an Mn?Mn separation of 4.064?(1)?Å, thus producing polymeric chains propagated in [101]. Weak inter-molecular C-H?O hydrogen bonds and ?-? inter-actions [centroid-centroid distance of 3.730?(3)?Å between the aromatic rings of neighbouring polymeric chains] further stabilize the crystal packing.

catena-Poly[[[triaqua-copper(II)]-?-pyridine-2,3-dicarboxyl-ato-?N,O:O] monohydrate].

Project description:In the title compound, {[Cu(C(7)H(3)NO(4))(H(2)O)(3)]·H(2)O}(n), the Cu(II) ion is bonded to three water mol-ecules, one N,O-bidentate pyridine-2,3-dicarboxyl-ate dianion and one O-bonded symmetry-generated dianion, resulting in a distorted CuNO(5) octa-hedral geometry. The bridging ligand results in an infinite chain. A network of O-H?O hydrogen bonds helps to establish the crystal structure.

catena-Poly[[triaqua-cadmium(II)]-μ-pyridine-2,3-dicarboxyl-ato-κN,O:O].

Project description:The title polymeric compound, [Cd(C(7)H(3)NO(4))(H(2)O)(3)](n) or [Cd(py-2,3-dc)(H(2)O)(3)](n), where py-2,3-dcH(2) is pyridine-2,3-dicarboxylic acid, was obtained by the reaction of cadmium(II) nitrate hexa-hydrate with (pipzH(2))(py-2,3-dc) as a proton-transfer compound in aqueous solution (pipz is piperazine). The mol-ecular structure shows that only the anionic fragment of the starting proton-transfer compound is present in the complex, while the (pipzH(2))(2+) dication has been lost. Each (py-2,3-dc)(2-) ligand bridges two Cd(II) atoms in two different coordination modes, i.e. one end acts as a monodentate and the other end as a bidentate ligand. The three remaining coordination sites on the metal center are occupied by water mol-ecules. The geometric arrangement of the six donor atoms around the Cd(II) atom is distorted octa-hedral. In the crystal structure, O-H⋯O and C-H⋯O hydrogen bonds play an important role in stabilizing the supra-molecular structure.
