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

ABSTRACT: 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.

Bis(?-2-methyl-quinolin-8-olato)-?N,O:O;?O:N,O-bis-[(methanol-?O)(nitrato-?O,O')lead(II)].

Project description:The mol-ecule of the title compound, [Pb(2)(C(10)H(8)NO)(2)(NO(3))(2)(CH(3)OH)(2)], lies about a centre of inversion. The Pb atom is chelated by nitrate and substituted quinolin-8-olate anions. The O atom of the quinolin-8-olate also bridges, to confer a six-coordinate status on the metal centre. When a longer Pb?O inter-action is considered, the geometry approximates a ?-cube in which one of the sites is occupied by a stereochemically active lone pair.

Project description: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.

(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.

Project description:The Pb(II) atom in the title compound, [Pb(C(10)H(8)NO)(2)], is chelated by two oxine (2-methyl-quinolin-8-olate) anions in a ?-trigonal-bipyramidal geometry; the N atoms occupy the axial sites. The mol-ecule lies about a twofold rotation axis.

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.

Dimethyl-bis-(2-methyl-quinolin-8-olato-?(2) N,O)tin(IV).

Project description:The Sn(IV) cation in the title compound, [Sn(CH3)2(C10H8NO)2], is N,O-chelated by two 2-methyl-quinolin-8-olate anions and coordinated by two methyl groups in a skew-trapezoidal bipyramidal geometry. In the mol-ecule, the two quinoline ring systems are twisted to one another at 10.91?(18)°. The dimethyl-tin skeleton [C-Sn-C = 149.6?(2)°] is bent over the longer edge of the trapezoid that is defined by the four chelating atoms. Weak inter-molecular C-H?O hydrogen bonding occurs in the crystal.

Tris(nitrato-κO,O')bis-(1,10-phenanthroline-κN,N')holmium(III).

Project description:In the title compound, [Ho(NO(3))(3)(C(12)H(8)N(2))(2)], the ten-coordinate Ho(III) ion is chelated by four N atoms from two phenanthroline (phen) ligands and six O atoms from three bidentate nitrate groups. The environment around the Ho atom can be described as a distorted bicapped square anti-prism. Two phenanthroline ligands form a dihedral angle of 43.72 (13)°. Short inter-molecular distances between the centroids of the six-membered rings [3.6887 (14)-3.8374 (16) Å] indicate the existence of π-π inter-actions, which link the mol-ecules into stacks extended in the [10] direction. The crystal packing is further stabilized by weak inter-molecular C-H⋯O hydrogen bonds.

Redetermination of di-aqua-tris-(4-oxo-pent-2-en-2-olato-?(2) O,O')lanthanum(III).

Project description:The structure of the title compound, [La(C5H7O2)3(H2O)2], has been redetermined to modern standards with anisotropic displacement parameters for all non-H atoms and the hydrogen-bonding pattern unambiguously established [for the previous study, see Phillips et al. (1968 ?). Inorg. Chem. 7, 2295-2299]. The La(3+) ion is coordinated by three O,O'-bidentate acetyl-acetate (acac(-)) ligands and two water mol-ecules, resulting in a fairly regular square-anti-prismatic LaO8 coordination geometry, with both aqua ligands part of the same square face. In the crystal, the neutral complex mol-ecules are linked into [110] chains by O-H?O hydrogen bonds.
