Catena-Poly[[chloridocobalt(II)]-μ-5-(8-quinolyloxymeth-yl)tetra-zolato-κN,O,N:N].

ABSTRACT: In the title compound, [Co(C(11)H(8)N(5)O)Cl](n), the Co(II) atom is penta-coordinated by one O atom and two N atoms from a 5-(8-quinolyloxymeth-yl)tetra-zolate ligand, one N atom from another symmetry-related ligand, and a Cl atom. The coordination geometry can be described as slightly distorted trigonal-bipyramidal. Adjacent Co atoms are connected by the bridging tetra-zole groups into a chain. The dihedral angle between the quinoline and tetra-zole planes is 21.2 (1)°. The structure involves intra- and inter-chain C-H⋯N hydrogen bonds.

Poly[(μ(2)-azido-κN:N)[μ(2)-5-(8-quinolyloxymeth-yl)tetra-zolato-κN,O,N:N]manganese(II)].

Project description:In the structure of the title compound, [Mn(C(11)H(8)N(5)O)(N(3))](n), the Mn atoms are hexa-coordinated by five N atoms and one O atom. The coordination polyhedron of the Mn atom is a slightly distorted octa-hedron. The Mn atoms are connected by azide anions with a μ(2)-1,1 mode and by 5-(8-quinolyloxymeth-yl)tetra-zolate ligands in a μ(2)-η(1)(N),η(3)-(N,N,O) fashion to form a two-dimensional framework parallel to the (100) plane. Geometric parameters of the organic ligand are in the normal ranges and the dihedral angle between the quinoline ring system and the tetra-zole unit is 7.41 (15)°. The structure involves intra- and inter-molecular C-H⋯N hydrogen bonds.

catena-Poly[[diiodidomercury(II)]-μ-nicotine-κN:N'].

Project description:The title polymeric complex, [HgI(2)(C(10)H(14)N(2))](n), was prepared from a solution of nicotine, mercury(II) iodide and 4-cyano-pyridine in dimethyl-formamide. Each nicotine mol-ecule is bonded to two Hg atoms, one through the pyrrolidine N atom and the other through the pyridine N atom, forming infinite zigzag polymeric chains. The coordin-ation around mercury is completed by two iodide ligands, resulting in a distorted tetra-hedral arrangement.

catena-Poly[[[tetra-aqua-zinc(II)]-μ-4,4'-bipyridine-κN:N'] naphthalene-1,5-disulfonate].

Project description:In the title complex, {[Zn(C(10)H(8)N(2))(H(2)O)(4)](C(10)H(6)O(6)S(2))}(n), the [Zn(4,4'-bipy)(H(2)O)(4)](2+) (4,4'-bipy is 4,4'-bipyridine) cations are linked into linear chains along [001] by the 4,4'-bipy ligands. The Zn(II) ion exhibits a slightly distorted octa-hedral coordination geometry in which the four water mol-ecules are in the equatorial positions. The anions are hydrogen bonded to the polycationic chains by O-H⋯O hydrogen bonds, forming a three-dimensional network. The Zn(II) ion, 4,4'-bipy ligand and anion lie on special positions of 2/m site symmetry.

catena-Poly[[tetra-kis-(μ-penta-fluoro-benzoato-κO:O')dimolybdenum(II)]-μ-4,4'-bipyridine-κN:N'].

Project description:In the title compound, [Mo(2)(C(7)F(5)O(2))(4)(C(10)H(8)N(2))](n), the mol-ecule forms a paddle-wheel-type structure. Each Mo(2) (4+) unit is equatorially coordinated by four pentafluoro-benzoate groups, while the axial positions are occupied by two 4,4'-bipyridine mol-ecules. The Mo-Mo bond length of 2.1227 (4) Å is representative of a dimolybdenum quadruple bond. An infinite linear chain parallel to [110] is formed by the Mo(2) (4+) unit coordinating axially to the two N atoms of the 4,4'-bipyridine ligand [Mo-N = 2.594 (2) Å]. The crystal packing shows mol-ecules linked together into a three-dimensional network via Mo-N coordination inter-actions and weak π-π stacking inter-actions between perfluoro-phenyl rings [centroid-centroid distance = 3.7280 (3) Å and centroid-to-plane distance = 3.6103 (12) Å between two penta-fluoro-phenyl rings].

Bis[μ-5-(5-carboxyl-ato-3-pyrid-yl)tetra-zolato-κN,N:N]bis-[triaqua-zinc(II)].

Project description:In the title complex, [Zn(2)(C(7)H(3)N(5)O(2))(2)(H(2)O)(6)], the 5-(5-carboxyl-ato-3-pyrid-yl)tetra-zolate ligand chelates the Zn(II) center through one pyridyl N and one tetra-zolate N atom, and uses another N atom to bridge to the second Zn atom, forming a centrosymmetric dinuclear unit. Three coordinated water mol-ecules complete the distorted octa-hedral geometry of the Zn(II) atom. O-H⋯O and O-H⋯N hydrogen bonds involving the coordinated water mol-ecules, tetra-zolate N atoms and the carboxyl-ate group result in a three-dimensional structure.

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.

catena-Poly[[[tetra-kis-(4-methyl-pyridine-κN)copper(II)]-μ-sulfato-κO:O'] 4.393-hydrate].

Project description:The structure of the title compound, {[Cu(SO(4))(C(6)H(7)N)(4)]·4.393H(2)O}(n), consists of Cu(2+) ions surrounded in a square-planar fashion by 4-methyl-pyridine ligands, forming two crystallographically independent Cu{H(3)C(C(5)H(4)N)}(4) units that are both located on crystallographic inversion centers. The Cu(4-methyl-pyridine)(4) units are, in turn, connected with each other via bridging sulfate anions, leading to the formation of infinite [Cu{H(3)C(C(5)H(4)N)}(4)SO(4)](n) zigzag chains along [001]. The completed coordination spheres of the Cu(2+) ions are slightly distorted octa-hedral. The axial Cu-O bonds are elongated [average length = 2.42 (4) Å] compared to the equatorial Cu-N bonds [average length = 2.043 (2) Å]. The inter-stitial space between the chains is filled with uncoordinated water mol-ecules that consolidate the structure through O-H⋯O hydrogen bonding. One of the five crystallographically independent solvent water mol-ecules is partially occupied with an occupancy factor of 0.396 (4). Due to hydrogen bonding between symmetry-equivalent water mol-ecules across inversion centers, several of the water H atoms are disordered in 1:1 ratios over mutually exclusive positions. The crystal under investigation was found to be non-merohedrally twinned in a 0.789 (1):0.211 (1) ratio by a 180° rotation around the reciprocal b axis.

Diaqua-bis[5-(2-pyridylmeth-yl)tetra-zolato-κN,N]manganese(II).

Project description:The title complex, [Mn(C(7)H(6)N(5))(2)(H(2)O)(2)], was obtained by the in situ hydro-thermal reaction of MnCl(2) with 2-(2-pyrid-yl)acetonitrile in the presence of NaN(3). The Mn(II) atom, which is located on an inversion centre, has a distorted octa-hedral coordination geometry formed by two water mol-ecules and two chelating ligands. Inter-molecular hydrogen bonds and π-π inter-actions (3.452 Å) stabilize the crystal structure and lead to the formation of a three-dimensional network.

Diaqua-bis[5-(2-pyrid-yl)tetra-zolato-κN,N]iron(II).

Project description:The title complex, [Fe(C(6)H(4)N(5))(2)(H(2)O)(2)], was synthesized by the reaction of ferrous sulfate with 5-(2-pyrid-yl)-2H-tetra-zole (HL). The Fe(II) atom, located on a crystallographic center of inversion, is coordinated by four N-atom donors from two planar trans-related deprotonated L ligands and two O atoms from two axial water mol-ecules in a distorted octa-hedral geometry. The Fe(II) mononuclear units are further connected by inter-molecular O-H⋯N and C-H⋯O hydrogen-bonding inter-actions, forming a three-dimensional framework.

Project description:In the title complex, [Zn(C(4)H(3)N(6))(2)(H(2)O)(2)], the metal centre lies on an inversion centre and displays a distorted octa-hedral ZnN(4)O(2) coordination geometry. The organic ligand is not planar; the dihedral angle between the imidazole and tetra-zole rings is 8.39 (9)°. An extended network of inter-molecular N-H⋯N and O-H⋯N hydrogen bonds stabilizes the crystal structure.
