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

ABSTRACT: 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 ?(3)-O atom and a ?(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).

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.

Octa-kis(2-chloro-benz-yl)di-?(2)-hydroxido-di-?(3)-oxido-bis-(2-phenyl-acetato)tetra-tin(IV).

Project description:The asymmetric unit of the title compound, [Sn(4)(C(7)H(6)Cl)(8)(C(8)H(7)O(2))(2)O(2)(OH)(2)], comprises one-half of the centrosymmetric tin(IV) complex. ?(3)-Oxide and ?(2)-hydroxide bridges link the four five-coordinate Sn(IV) atoms to generate three fused four-membered Sn-O-Sn-O rings in a ladder-like structure. The two endocyclic Sn atoms each bind to two ?(3)-oxide anions and a ?(2)-hydroxide ligand, together with two 2-chloro-benzyl groups. The exocyclic Sn atoms each carry a monodentate phenyl-acetate ligand, two 2-chloro-benzyl groups, and ?(3)-oxide and ?(2)-hydroxide ligands. Both types of Sn atoms adopt a distorted trigonal-bipyramidal coordination geometry. The mol-ecular conformation is stabilized by intra-molecular O-H?O inter-actions involving the ?(2)-hydroxide ligands and the C=O group of the phenyl-acetate ligand.

Octa-butyl-bis-(?(2)-2-chloro-5-nitro-benzoato)bis-(2-chloro-5-nitro-benzoato)di-?(3)-oxido-tetra-tin(IV).

Project description:The title complex, [Sn(4)(C(4)H(9))(8)(C(7)H(3)ClNO(4))(4)O(2)], is a cluster formed by a crystallographic inversion center around the central Sn(2)O(2) ring. Both of the two independent Sn atoms are five-coordinated, with distorted trigonal-bipyramidal SnC(2)O(3) geometries. One Sn atom is coordinated by two butyl groups, one O atom of the benzoate anion and two bridging O atoms, whereas the other Sn atom is coordinated by two butyl groups, two O atoms of the benzoate anions and a bridging O atom. The O atoms of the bridging benzoate anion are disordered over two sites with an occupancy ratio of 0.862?(12):0.138?(12). One of the butyl groups coordinated to the Sn(2)O(2) ring is disordered over two sites with an occupancy ratio of 0.780?(8):0.220?(8), whereas both of the two butyl groups coordinated to the other Sn atom are disordered over two sites with occupancy ratios of 0.788?(5):0.212?(5) and 0.827?(10):0.173?(10). All the butyl groups are equatorial with respect to the SnO(3) trigonal plane. In the crystal, complex mol-ecules are stacked down [010] with weak inter-molecular C-H?? inter-actions stabilizing the crystal structure.

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.

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.

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.

Octa-methyl-bis-(?(2)-2-methyl-benzoato-?O:O')bis-(2-methyl-benzoato-?O)di-?(3)-oxido-tetra-tin(IV).

Project description:The title compound, [Sn(4)(CH(3))(8)(C(8)H(7)O(2))(4)O(2)], is a distann-oxane derivative of 2-methyl-benzoic acid. The crystal structure is composed of centrosymmetric dimers lying about inversion centres. Both independent Sn atoms adopt distorted trigonal-bipyramidal SnC(2)O(3) coordination geometries with the basal planes consisting of two C-atoms from the methyl groups and a bridging O atom. The Sn-C and Sn-O bond lengths lie in the ranges 2.090?(2)-2.104?(3) and 2.0241?(14)-2.2561?(15)?Å, respectively. The central four-membered planar Sn(2)O(2) ring [Sn?Sn distance = 3.2993?(2)?Å] makes dihedral angles of 5.43?(11) and 59.50?(7)° with the methyl-phenyl groups, which are themselves oriented at a dihedral angle of 61.38?(8)°. Besides weak C-H?O and C-H?? inter-actions, the packing mainly features van der Waals forces between the mol-ecules.

Octa-butyl-bis{(E)-2-[4-(2-hydroxy-benzyl-ideneamino)phen-yl]acetato}di-?(2)-methoxo-di-?(3)-oxido-tetra-tin(IV).

Project description:The title compound, [Sn(4)(C(4)H(9))(8)(C(15)H(12)NO(3))(2)(CH(3)O)(2)O(2)], is a centrosymmetric dimer and displays a ladder type structural motif. There are four Sn(IV) centres which can be divided into two sorts, viz. two endocyclic and two exocyclic. The endo- and exocyclic Sn(IV) centres are linked by bidentate deprotonated methanol and ?(3)-O atoms. Each exocyclic Sn(IV) centre is also coordinated by a monodentate 2-[4-(2-hydroxy-benzyl-idene-amino)phen-yl]acetate ligand. Parts of the butyl groups were found to be disordered over two sets of sites.
