Bis(?(2)-quinoline-2-carboxyl-ato)-?N,O:O;?O:N,O-bis-[(acetato-?O)(ethanol-?O)lead(II)].

ABSTRACT: In the centrosymmetric dinuclear title compound, [Pb(2)(C(10)H(6)NO(2))(2)(CH(3)COO)(2)(C(2)H(5)OH)(2)], one O atom of the carboxyl-ate group of the quinoline-2-carboxyl-ate anion connects the two Pb(II) atoms. The Pb(II) atom is surrounded by four O atoms and one N atom in a ?-octa-hedral PbO(4)NE geometry (E is the electron lone pair). Two longer Pb?O inter-actions distort the geometry towards a ?-square-anti-prism. Inter-molecular O-H?O hydrogen bonds link the mol-ecules.

In the centrosymmetric dinuclear title compound, [Pb(2)(C(10)H(6)NO(2))(2)(CH(3)COO)(2)(C(2)H(5)OH)(2)], one O atom of the carboxyl-ate group of the quinoline-2-carboxyl-ate anion connects the two Pb(II) atoms. The Pb(II) atom is surrounded by four O atoms and one N atom in a Ψ-octa-hedral PbO(4)NE geometry (E is the electron lone pair). Two longer Pb⋯O inter-actions distort the geometry towards a Ψ-square-anti-prism. Inter-molecular O-H⋯O hydrogen bonds link the mol-ecules. ...[more]

Bis(methanol-κO)bis-(quinoline-2-carboxyl-ato-κN,O)nickel(II).

Project description:In the title complex, [Ni(C(10)H(6)NO(2))(2)(CH(3)OH)(2)], the Ni(II) ion lies on an inversion center and is coordinated by two quinoline-2-carboxyl-ate ligands in the equatorial sites and two axial methanol ligands, forming a distorted octa-hedral environment. In the crystal, mol-ecules are linked via O-H⋯O hydrogen bonds into a two-dimensional network parallel to (10[Formula: see text]).

trans-Bis(methanol-κO)bis-(quinoline-2-carboxyl-ato-κN,O)manganese(II).

Project description:The title compound, [Mn(C(10)H(6)NO(2))(2)(CH(4)O)(2)], was obtained unintentionally as the product of an attempt to synthesize a polynuclear carboxyl-ate bridged manganese(III/IV) complex, using methanol to reduce the permanganate ion. The mol-ecule is centrosymmetric; the pairs of equivalent ligands coordinate trans to each other in a distorted octa-hedral geometry. Intra-molecular C-H⋯O bonds lying in the equatorial plane stabilize the mol-ecule. In the crystal, mol-ecules are linked by O-H⋯O and C-H⋯O hydrogen bonds, creating a three-dimensional supra-molecular structure. π-π and C-H⋯π inter-actions are also observed. The dihedral angle and centroid-to-centroid distance between the pyridine ring (A) and the benzene ring (B(i)) of a symmetrically related mol-ecule [symmetry code: (i) -1 - x, -y, -z] are 1.27 (11)° and 3.974 (2) Å, respectively. For the C-H⋯π inter-actions, the relevant distances and angles are: C⋯Cg[A(ii)] = 3.643 (2) Å, H⋯Cg[A(ii)] = 2.750 (2) Å and C-H⋯Cg[A(ii)] = 155 (1)° [symmetry code: (ii) x, -1 + y, z].

Bis(μ-pyridazine-3-carboxyl-ato-κO:O')bis-[aqua-dioxido(pyridazine-3-carboxyl-ato-κN,O)uranium(VI)] dihydrate.

Project description:The structure of the binuclear title complex, [U(2)(C(5)H(3)N(2)O(2))(4)O(4)(H(2)O)(2)]·2H(2)O, is composed of centrosymmetric dimers in which each UO(2) (2+) ion is coordinated by two ligand mol-ecules. One donates its N,O-bonding group and the other donates both carboxyl-ate O atoms. Each of the latter bridges adjacent uranyl ions. The coordination environment of the metal center is a distorted penta-gonal bipyramid. The dimers are inter-connected by O-H⋯O hydrogen bonds between coordinated and uncoordinated water mol-ecules and carboxyl-ate O atoms. An intra-molecular O-H⋯N inter-action is also present.

Bis(μ-5-carboxyl-ato-1-carboxyl-ato-methyl-2-oxidopyridinium)-κO:O;κO:O-[diaqua-(phenan-throline-κN,N')manganese(II)] dihydrate.

Project description:The centrosymmetric binuclear title complex, [Mn(2)(C(8)H(5)NO(5))(2)(C(12)H(8)N(2))(2)(H(2)O)(4)]·2H(2)O, was obtained by the reaction of manganese chloride with 5-carb-oxy-1-carboxy-methyl-2-oxidopyridinium and 1,10-phenanthroline. The Mn(II) atom is coordinated by two N atoms from the 1,10-phenanthroline ligand, two O atoms from two 5-carboxyl-ato-1-carboxyl-atomethyl-2-oxidopyridinium ligands and two water mol-ecules, leading to a distorted octahedral MnN(2)O(4) environment. Inter-molecular O-H⋯O hydrogen bonds link neighbouring mol-ecules into a layer structure parallel to (001).

catena-Poly[cobalt(II)-bis-(μ-3,7-dichloro-quinoline-8-carboxyl-ato-κN,O:O')].

Project description:In the crystal structure of the title compound, [Co(C(10)H(4)Cl(2)NO(2))(2)](n), the Co(II) cation lies on a twofold rotation axis. Each cation is N,O-chelated by the carboxyl-ate anions of two 3,7-dichloro-quinoline-8-carboxyl-ate ligands. The second carboxyl-ate O atom of each ligand coordinates to the Co(II) cation of an adjacent mol-ecule, linking the cations into a linear chain. Strong inter-chain π-π stacking inter-actions are observed in the crystal structure (perpendicular distance 3.42 Å, centroid-to-centroid distance 3.874 Å).

(Benzoato-κO,O')(quinoline-2-carboxyl-ato-κN,O)(quinoline-2-carboxylic acid-κN,O)copper(II).

Project description:The crystal structure of the title compound, [Cu(C(10)H(6)NO(2))(C(7)H(5)O(2))(C(10)H(7)NO(2))], contains copper(II) ions five-coordinated in a distorted trigonal-bipyramidal environment. The equatorial plane is occupied by three O atoms, one from the carboxyl-ate group of the benzoate ion considered as occupying a single coordination site, the other two from two carboxyl-ate groups of the quinaldic acid and quinaldate ligands. The axial positions are occupied by the N atoms of the quinoline ring system. The metal ion lies on a twofold axis that bisects the benzoate ion. The quinaldate and quinaldic acid ligands are equivalent by symmetry, and the carboxyl-ate/carboxyl groups are disordered. The disordered H atom is shared between the carboxyl-ate groups of adjacent quinaldic acid mol-ecules. Such hydrogen bonds delineate zigzag chains that run along the c axis. The structure is very similar to that of the Mn(II) analog.

(Benzoato-κO,O')(quinoline-2-carboxyl-ato-κN,O)(quinoline-2-carboxylic acid-κN,O)manganese(II).

Project description:The crystal structure of the title compound, [Mn(C(7)H(5)O(2))(C(10)H(6)NO(2))(C(10)H(7)NO(2))], contains manganese(II) ions six-coordinated in a distorted octa-hedral environment. The equatorial plane is occupied by four O atoms, two from the carboxyl-ate group of the benzoate ion, the other two from carboxyl-ate/carboxyl groups of the quinaldate/quinaldic acid mol-ecules. The axial positions are occupied by the N atoms of the quinoline ring systems. The metal ion lies on a twofold rotation axis that bisects the benzoate ligand; the quinaldate and quinaldic acid ligands are therefore equivalent by symmetry, and the carboxylate/carboxyl groups are disordered. The complexes are joined together by hydrogen bonds between the carboxyl-ate/carboxyl groups of adjacent quinaldate/quinaldic acid mol-ecules, forming zigzag chains that run along the c axis.

Bis[μ-2-(2-carboxyl-atophen-yl)acetato]-κO,O:O;κO:O,O-bis-[aqua-(1,10-phenanthroline-κN,N')nickel(II)].

Project description:The title compound, [Ni(2)(C(9)H(6)O(4))(2)(C(12)H(8)N(2))(2)(H(2)O)(2)], is isostructural with the Zn(II) analogue. Each Ni(II) atom is coordinated in a distorted octa-hedral geometry by three O atoms from two homophthalate anions, one aqua O atom and two 1,10-phenanthroline N atoms. The two Ni(II) atoms are linked by two bridging homophthalate dianions into a centrosymmetric dinuclear unit. The dinuclear units are linked into one-dimensional ladder-like chains along [100] by O-H⋯O hydrogen bonds between the coordinated water mol-ecules and one of the O atoms of the carboxyl-atomethyl group.

Bis(quinoline-2-carboxyl-ato-?N,O)lead(II).

Project description:The Pb(II) atom in the title compound, [Pb(C(10)H(6)NO(2))(2)], is N,O-chelated by two quinoline-2-carboxyl-ate anions in a distorted ?-trigonal-bipyramidal environment; four atoms are connected to the Pb(II) atom by regular coordination bonds. The structure also features two somewhat long Pb?O inter-actions [2.952?(3) and 3.014?(3)?Å]. These long inter-actions give rise to a layer coordination polymer having the lead atom in a distorted ?-monocapped octa-hedral geometry.

Bis(?-quinoline-2-carboxyl-ato)-?N,O:O;?O:N,O-bis-[(acetato-?O,O')(methanol-?O)lead(II)].

Project description:The dinuclear title compound, [Pb(2)(C(10)H(6)NO(2))(2)(CH(3)COO)(2)(CH(3)OH)(2)], lies across an inversion center. The methanol-coordinated Pb(II) atom is chelated by the acetate anion as well as by the quinoline-2-carboxyl-ate anion. One O atom of the quinoline-2-carboxyl-ate anion bridges two symmetry-related Pb(II) atoms, forming the dinuclear compound. Aside from the six atoms connected to the Pb(II) atom by regular coordination bonds, the structure features a long Pb?O inter-action [3.145?(3)?Å] that gives rise to a distorted ?-square-anti-prismatic geometry at the metal center. The H atom of the methanol is hydrogen bonded to an O atom of the acetate.
