Di-?(2)-methano-lato-bis-(?-4-methyl-5-sulfanyl-idene-4,5-dihydro-1H-1,2,4-triazolido-?N:N)di-?(3)-oxido-tetra-kis-[dibutyltin(IV)].

ABSTRACT: The asymmetric unit of the title distannoxane, [Sn(4)(C(4)H(9))(8)(C(3)H(4)N(3)S)(2)(CH(3)O)(2)O(2)], contains two mol-ecules, each of which lies about an individual center of inversion. The tetra-nuclear mol-ecule features a three-rung-staircase Sn(4)O(4) core in which two independent Sn(IV) atoms are bridged by the triazolide group. The negatively charged N atom of the triazolide group binds to the terminal Sn atom at a shorter distance [Sn-N = 2.262?(3), 2.254?(3)?Å] compared with the neutral N atom that binds to the central Sn atom[SnN = 2.617?(4); 2.830?(3)?Å]. The oxide O atom is three-coordinate whereas the methano-late O atom is two-coordinate. The terminal Sn atom is five-coordinate in a cis-C(3)SnNO trigonal-bipyramidal environment, whereas the central Sn atom is six-coordinate in a C(2)SnNO(3) skew-trapezoidal-bipyramidal geometry.

Project description:The title distannoxane, [Sn(4)(CH(3))(8)(C(3)H(4)N(3)S)(2)(CH(3)O)(2)O(2)], lies about a center of inversion; the tetra-nuclear mol-ecule features a three-rung-staircase Sn(4)O(4) core in which the two crystallographically independent Sn(IV) atoms are bridged by the triazolide group. The negatively charged N atom of the triazolide group binds to the terminal Sn atom at a shorter distance [Sn-N = 2.239 (2) Å] compared with the neutral N atom that binds to the central Sn atom [Sn← N = 2.757 (3) Å]. The oxide O atom is three-coordinate whereas the methano-late O atom is two-coordinate. The terminal Sn atom is five-coordinate in a cis-C(3)SnNO trigonal-bipyramidal environment, whereas the central Sn atom is six-coordinate in a C(2)SnNO(3) skew-trapezoidal-bipyramidal geometry.

Di-μ(3)-oxido-bis-(μ(2)-quinaldato-κO:O)-bis-(quinaldato-κN,O)tetra-kis[di-n-butyl-tin(IV)].

Project description:The title tetra-nuclear Sn(IV) complex, [Sn(4)(C(4)H(9))(8)(C(10)H(6)NO(2))(4)O(2)], is a cluster built up by inversion symmetry around the central Sn(2)O(2) ring. The coordination geometries of the Sn atoms involved can be classified into two types: the five-coordinate Sn atoms of the central Sn(2)O(2) core have a trigonal-bipyramidal geometry, with axial positions occupied by a μ(3)-O atom and a μ(2)-O atom belonging to the nonchelating quinaldate ligand. The peripheral Sn atoms are six-coordinate, with a distorted octa-hedral geometry. The methyl group of an n-butyl ligand is disordered over two sites, with occupancies of 0.643 (12) and 0.357 (12).

Tetra-μ(3)-methano-lato-tetra-kis-[(2-formyl-6-meth-oxy-phenolato)methano-lnickel(II)].

Project description:The molecule of the title compound, [Ni(4)(CH(3)O)(4)(C(8)H(7)O(3))(4)(CH(3)OH)(4)], has S(4) symmetry. Each of the four Ni(II) atoms occupies every other corner of a cube, with the alternate corners occupied by μ(3)-methano-late bridging groups linking to three Ni(II) atoms. Each Ni(II) atom is in an O(6) octa-hedral coordination environment formed by three O atoms from three μ(3)-methano-late groups, one from methanol, and two others from a bidentate 2-formyl-6-meth-oxy-phenolate ligand. The Ni-O bond distances range from 2.0020 (14) to 2.0938 (14) Å, the cis bond angles range from 81.74 (6) to 97.63°, and the trans bond angles range from 168.76 (5) to 175.22 (6)°. There are bifurcated hydrogen-bonding inter-actions between the coordinated methanol OH groups and both the phenolic and meth-oxy O atoms of an adjoining 2-formyl-6-meth-oxy-phenolate moiety. In addition, there are weak inter-molecular C-H⋯O inter-actions involving the meth-oxy O atoms.

Dichloridoocta-kis(4-chloro-benz-yl)di-μ(2)-hydroxido-di-μ(3)-oxido-tetra-tin(IV) toluene solvate.

Project description:The title stannoxane is a toluene-solvated dimer, [Sn(4)(C(7)H(6)Cl)(8)Cl(2)O(2)(OH)(2)]·C(7)H(8), the tetra-nuclear mol-ecule lying across a center of inversion. The Sn(4)O(4) framework, whose two independent Sn atoms show trigonal bipyramidal coordination, is essentially planar (r.m.s deviation = 0.02 Å). One of the two chloro-benzyl groups of the chloridodiorganyltin unit is disordered over two positions with the chloro-phenyl residue refined over two positions in a 50:50 ratio. The solvent mol-ecule is disordered about a twofold axis.

Hexa-μ(2)-chlorido-μ(4)-oxido-tetra-kis-[(3-methyl-5-phenyl-1H-pyrazole-κN)copper(II)].

Project description:The title compound, [Cu(4)Cl(6)O(C(10)H(10)N(2))(4)], contains four Cu(II) atoms which are bridged by six chloride anions. The central O atom is located on a crystallographic fourfold roto-inversion axis. Each Cu(II) atom is coordinated by an N atom of a neutral monodentate 3-methyl-5-phenyl-pyrazole ligand, three Cl(-) anions, and one O(2-) anion. The geometry at each Cu(II) atom is distorted trigonal-bipyramidal, with the three Cl(-) ions in the equatorial plane and the N and O atoms in the axial positions.

Tetrakis(mu2-4-aminobenzoato)di-mu3-oxido-tetrakis[dibutyltin(IV)].

Project description:The molecule of the title compound, [Sn(4)(C(4)H(9))(8)(C(7)H(6)NO(2))(4)O(2)], lies about an inversion centre and is a tetranuclear bis(tetrabutyldicarboxylatodistannoxane) complex containing a planar Sn(4)O(2) core in which two mu(3)-oxide O atoms connect an Sn(2)O(2) ring to two exocyclic Sn atoms. Each Sn atom has a highly distorted octahedral coordination. In the molecule, the carboxylate groups of two aminobenzoate ligands bridge the central and exocyclic Sn atoms, while two further aminobenzoate ligands have highly asymmetric bidentate chelation to the exocyclic Sn atoms plus long O...Sn interactions with the central Sn atoms. Each Sn atom is also coordinated by two pendant n-butyl ligands, which extend roughly perpendicular to the plane of the Sn(4)O(10) core. Only one of the four unique hydrogen-bond donor sites is involved in a classic N-H...O hydrogen bond, and the resulting supramolecular hydrogen-bonded structure is an extended two-dimensional network which lies parallel to the (100) plane and consists of a checkerboard pattern of four-connected molecular cores acting as nodes. The amine groups not involved in the hydrogen-bonding interactions have significant N-H...pi interactions with neighbouring aminobenzene rings.

(Methanol-κO)(methano-lato-κO)oxido{N'-[1-(2-oxidonaphthalen-1-yl-κO)ethyl-idene]nicotinohydrazidato-κN',O}vanadium(V).

Project description:The title oxovanadium(V) complex, [V(C(18)H(13)N(3)O(2))(CH(3)O)O(CH(3)OH)], was obtained by the reaction of 1-(2-hy-droxy-naphthalen-1-yl)ethanone, nicotinohydrazide and vanadyl sulfate in methanol. The V(V) atom is six-coordinated by the N,N,O-tridentate Schiff base ligand, one methano-late O atom, one methanol O atom and one oxide O atom, forming a distorted octa-hedral geometry. The methanol O atom lies trans to the V=O group. The dihedral angle between the pyridine ring and the naphthalene ring system is 31.52 (10)°. In the crystal, inversion dimers linked by pairs of O-H⋯N hydrogen bonds occur.

Poly[[tetra-kis-(μ-1,2-di-4-pyridyl-ethyl-ene-κN:N')tetra-kis-(seleno-cyanato-κN)dimanganese(II)] 1,2-di-4-pyridyl-ethyl-ene disolvate].

Project description:The crystal structure of the title compound, {[Mn(NCSe)(2)(C(12)H(10)N(2))(2)]·C(12)H(10)N(2)}(2n), consists of two crystallographically independent Mn cations, four seleno-cyanate anions, four 1,2-di-pyridylethylene (bpe) ligands (two of which are located on centers of inversion) and two bpe solvent molecules. Each manganese(II) cation is coordinated by two terminally N-bonded seleno-cyanate anions and four bpe ligands within a slightly distorted octa-hedron. The manganese(II) cations are linked by the bpe ligands into chains that are further connected by these ligands into layers. These layers are stacked, forming cavities in which additional bpe solvent molecules are embedded.

Crystal structure of tetrakis-(acetyl-acetonato)di-chloridodi-μ3-methano-lato-tetra-μ2-methano-lato-tetra-iron(III).

Project description:The title complex, [Fe4(C5H7O2)4(CH3O)6Cl2] or [Fe4(acac)4(μ2-OMe)4(μ3-OMe)2Cl2] (acac = acetyl-acetonate), crystallizes in the ortho-rhom-bic Pbca space group with one half of the mol-ecule per asymmetric unit, the other half being completed by inversion symmetry. The core structure consists of a face-sharing double pseudo-cubane entity with two opposite corners missing. Weak C-H⋯Cl inter-molecular inter-actions result in a two-dimensional layered structure parallel to the ac plane.
