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

ABSTRACT: 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:Mol-ecules of the title compound, [Zn(8)(C(6)F(5))(8)O(4)(C(4)H(10)O)(4)], are located on a special position of site symmetry [Formula: see text]. As a result, there is just one quarter-mol-ecule in the asymmetric unit. The title compound features a Zn(4)O(4) cube. Each Zn atom in the cube carries a pentafluorophenyl substituent. Each O atom is bonded to a further Zn atom, which is connected to a pentafluorophenyl substituent and the O atom of a diethyl ether mol-ecule. All ether C atoms are disordered over two sets of sites with a site occupation factor of 0.51?(2) for the major occupied site.

Octa-methyldi-?(3)-oxido-bis-(?(2)-thio-phene-3-acetato-?O:O')(thio-phene-3-acetato-?O)tetra-tin(IV).

Project description:In the centrosymmetric title compound, [Sn(4)(CH(3))(8)(C(6)H(5)O(2)S)(4)O(2)], the central four-membered planar ring (Sn(2)O(2)) makes dihedral angles of 66.28?(12) and 77.43?(11)° with the heterocyclic rings of the bridging and monodentate ligands, respectively. One Sn(IV) atom adopts a distorted SnO(3)C(2) trigonal-bipyramidal geometry, with both C atoms in equatorial sites and the other a grossly distorted SnO(4)C(2) octa-hedral or irregular arrangement. In the crystal, the mol-ecules are connected into pillar-like polymeric units making R(2) (2)(12) ring motifs due to inter-molecular C-H?O inter-actions. C-H?? inter-actions are also present. The O atoms of the chelating ligands and the S atom of the monodentate ligand are disordered over two sets of sites in a 0.65?(6):0.35?(6) ratio.

Tetra-kis(2,2'-bipyrid-yl)dichlorido-di-?(3)-hydroxido-di-?(2)-hydroxido-tetra-copper(II) dinitrate hexa-hydrate.

Project description:The tetra-nuclear copper(II) title complex, [Cu(4)Cl(2)(OH)(4)(C(10)H(8)N(2))(4)](NO(3))(2)·6H(2)O, has a crystallographically imposed centre of symmetry. The metal atoms display a distorted tetragonal-pyramidal coordination geometry, and are linked by two ?(2)- and two ?(3)-hydroxo groups, assuming a chair-like conformation for the Cu(4)O(2) core. In the crystal, the complex mol-ecules are linked into a three-dimensional network by inter-molecular O-H?O, O-H?Cl, C-H?O and C-H?Cl hydrogen bonds and ?-? stacking inter-actions with centroid-centroid separations of 3.724?(2) and 3.767?(3)?Å.

Di-?(3)-oxido-bis-(?(2)-quinaldato-?O:O)-bis-(quinaldato-?N,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 ?(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).
