Bis(?-2-methyl-8-oxidoquinolin-1-ium-?O:O)bis-[(acetato-?O,O')(2-methyl-8-oxidoquinolin-1-ium-?O)bis-(nitrato-?O,O')lanthanum(III)].

ABSTRACT: The N-heterocycles in the centrosymmetric title compound, [La(2)(C(10)H(9)NO)(4)(CH(3)COO)(2)(NO(3))(4)], exist in the zwitterionic form. One heterocycle binds to a metal center whereas the other bridges two metal centers. Each La atom is chelated by an acetate and two nitrate groups and is surrounded by nine O atoms in a distorted tricapped trigonal-prismatic coordination environment. The N-H groups form intra-molecular N-H?O hydrogen bonds. One of the nitrate ions is disordered over two positions in a 0.80?(3):0.20?(3) occupancy ratio.

Project description:The two independent N-heterocycles in the centrosymmetric title compound, [La(2)(C(10)H(9)NO)(4)(NO(3))(6)], exist in the zwitterionic form. One of these binds to one metal center, whereas the other bridges two metal centers. The La atom is chelated by three nitrate groups and is surrounded by nine O atoms in a coordination environment based on a distorted monocapped square-anti-prism. The dinuclear structure is further stabilized by intra-molecular N-H?O(nitrate) hydrogen bonds.

(Methanol-κO)bis-{2-meth-oxy-6-[(4-methyl-phen-yl)iminiometh-yl]phenolato-κO,O'}tris-(nitrato-κO,O')lanthanum(III).

Project description:The asymmetric unit of title compound, [La(NO(3))(3)(C(15)H(15)NO(2))(2)(CH(3)OH)], consists of two Schiff base 2-meth-oxy-6-[(4-methyl-phen-yl)iminiometh-yl]phenolato (HL) ligands, three independent nitrate anions and one methanol mol-ecule coordinated to La(III). The coordination environment of the La(III) ion is formed by eleven O atoms. Three bidentate nitrate anions coordinate to the La(III) ion, while two HL ligands chelate the metal center with O atoms from the phenolate and meth-oxy groups. The HL ligands are zwitterionic, with protonated imine N atoms. The coordination sphere is completed by one methanol mol-ecule. The protonated imine N atoms are involved in intra-molecular N-H⋯O hydrogen bonds with the phen-oxy groups and nitrate ligands. One O atom of one nitrate group is disordered over two sites of equal occupancy.

catena-Poly[[tetra-kis(hexa-methyl-phospho-ramide-?O)bis-(nitrato-?O,O')lanthanum(III)] [silver(I)-di-?(2)-sulfido-tungstate(VI)-di-?(2)-sulfido]].

Project description:Hexamethyl-phospho-ramide (hmp), tetra-thio-tungstate(VI), silver sulfide and lanthanum(III) nitrate are self-assembled to form discrete cations one-dimensional poylmeric anionic chains [AgWS(4)](n) (n) (-) in the title compound, {[La(NO(3))(2)(C(6)H(18)N(3)OP)(4)][AgWS(4)]}(n). The central La atom in the cation is coordinated by eight O atoms from two nitrate and four hmp ligands. Together with the two nitrate ligands, the cation is monovalent, which leads to the anionic chain having a monovalent repeat unit. The polymeric anionic chain with W?Ag?W and Ag?W?Ag angles of 165.94?(3) and 155.894?(14)° presents a distorted linear configuration. Five N atoms, 18 C atoms and their attached H atoms are disordered equally over two positions.

Bis[μ-4-(1H-imidazol-3-ium-1-yl)benzoato-κO:O']bis-[(methanol)tris-(nitrato-κO,O')terbium(III)].

Project description:In the centrosymmetric dinuclear title complex, [Tb(2)(NO(3))(6)(C(10)H(8)N(2)O(2))(2)(CH(3)OH)(2)], the Tb atoms are bridged by the carboxyl-ate groups of the two 4-(1H-imidazol-3-ium-1-yl)benzoate (iba) ligands. The iba ligand adopts a zwitterionic form with a protonated imidazole group. The Tb atom adopts a distorted tricapped trigonal-prismatic coordination geometry and is coordinated by six O atoms of three chelating nitrate ions, one O atom of the methanol mol-ecule and two O atoms of two iba ligands. The intra-molecular Tb⋯Tb separation is 5.1419 (3) Å. O-H⋯O and N-H⋯O hydrogen bonds connect complex mol-ecules into a two-dimensional network.

Diaqua-bis[6-(3,5-dimethyl-1H-pyrazol-1-yl)picolinato-?N,N',O](nitrato-?O,O')lanthanum(III) monohydrate.

Project description:In the title complex, [La(C(11)H(10)N(3)O(2))(2)(NO(3))(H(2)O)(2)]·H(2)O, the La atom is coordinated by four N atoms and six O atoms derived from two 6-(3,5-dimethyl-1H-pyrazol-1-yl)picolinate ligands, one nitrate anion and two water mol-ecules. The mol-ecules are linked together via hydrogen bonds involving the water mol-ecules, forming a three-dimensional network.

Crystal structure of bis-(μ2-meth-anolato-κO:κO)hexa-methyl-bis-(μ2-tri-phenyl-acetato-κO:κO')bis-(μ2-tri-phenyl-acetato-κ2 O,O':κO)dialuminiumdi-lanthanum toluene tetra-solvate.

Project description:The title compound, [Al2La2(C20H15O2)4(CH3)6(CH3O)2]·4CH3C6H5 or [{La(Ph3CCOO)2(Me3AlOMe)}2]·4CH3C6H5, was formed in a reaction between lanthanum tris-(tetra-methyl-aluminate) and tri-phenyl-acetic acid (1:1) with unintended partial oxidation. The tri-phenyl-acetate ligand exhibits μ2-κ1 O:κ1 O' bridging and μ2-κ2 O,O':κ1 O semi-bridging coordination modes, forming a dimeric La2(μ-OCO)4 core. The semi-bridging tri-phenyl-acetate group provides additional bonding with an La3+ cation via the π-system of one of its phenyl rings. The tri-methyl-meth-oxy-aluminate anion, which is coordinated to the La3+ cation by its O atom, displays a rather long La-CMe bond. Two toluene mol-ecules are each disordered over two orientations about centres of symmetry with site occupancy factors of 0.5. The title compound represents the first example of an LnIII complex containing both alkyl alkoxide aluminate and π-bounded arene fragments.

Bis(2,2'-bipyridyl-?N,N')(nitrato-?O,O')(trifluoro-acetato-?O)cadmium(II).

Project description:In the title complex, [Cd(C(2)F(3)O(2))(NO(3))(C(10)H(8)N(2))(2)], the Cd(II) ion is hepta-coordinated by two chelating 2,2'-bipyridyl ligands [Cd?N 2.370?(6)-2.416?(6)?Å], one carboxyl-ate O atom [Cd?O 2.290?(6)?Å] from the trifluoro-acetate ligand and two O atoms [Cd?O 2.386?(6), 2.633?(6)?Å] from a chelating nitrate anion. The trifluoro-methyl fragment is rotationally disordered between two orientations in a 0.640?(7):0.360?(7) ratio. In the crystal, weak inter-molecular C-H?O hydrogen bonds contribute to the crystal packing stability.

Bis(2-amino-6-methyl-pyrimidin-1-ium-4-olate-?N,O)bis-(nitrato-?O,O')cadmium(II).

Project description:In the title compound, [Cd(NO(3))(2)(C(5)H(7)N(3)O)(2)], the Cd(II) atom is eight-coordinated by two amine N atoms and two O atoms from two zwitterionic, biodentate 2-amino-6-methyl-pyrimidin-1-ium-4-olate ligands and by four O atoms from two nitrate groups. Intra-molecular N-H?O hydrogen bonds occur. The crystal packing is stabilized by inter-molecular N-H?O and C-H?O hydrogen bonds, two of which are bifurcated, between the nitrate anions and the organic groups.

Poly[[tetra-?(3)-acetato-hexa-?(2)-acetato-diaqua-?(2)-oxalato-tetra-lanthanum(III)] dihydrate].

Project description:The title compound, {[La(4)(CH(3)CO(2))(10)(C(2)O(4))(H(2)O)(2)]·2H(2)O}(n), exhibits a two-dimensional layered structure with the oxalate and acetate ligands acting as bridges. The asymmetric unit contains two crystallographically independent lanthanum(III) ions, half of an oxalate ligand, five acetate ligands, one coordinated water mol-ecule and one uncoordinated water mol-ecule. The coordination numbers of the two La ions are 9 and 10. Adjacent layers of the structure, which extend parallel to (100), are linked by O-H?O hydrogen bonds and are also held together by van der Waals inter-actions between the CH(3) groups of the acetate anions.

Bis(hexa-methyl-enetetra-mine)bis-(tri-chloro-acetato)copper(II).

Project description:In the title compound, [Cu(C(2)Cl(3)O(2))(2)(C(6)H(12)N(4))(2)], the Cu(II) ion (site symmetry 2) is coordinated by two trichloro-acetate anions and two hexa-methyl-enetetra-mine mol-ecules, resulting in a distorted CuN(2)O(2) geometry that is inter-mediate between tetra-hedral and square planar. The Cl atoms are disordered over two sets of sites, with relative occupancies of 0.749?(7) and 0.251?(7). In the crystal, the packing is consolidated by inter-molecular C-H?O inter-actions.
