Di-?-nicotinato-?N:O;?O:N-bis-[aqua-bis-(4-bromo-benz-yl)(nicotinato-?O,O')tin(IV)].

ABSTRACT: Two nicotinate binding modes are observed in the dinuclear title compound, [Sn(2)(C(7)H(6)Br)(4)(C(6)H(4)NO(2))(4)(H(2)O)(2)]: in the first, a terminal O,O'-chelating molecule binds to a water-coordinated diorganotin cation, while the second mode corresponds to an O:N-bridging molecule which binds to two cations. The two Sn atoms exist in trans-C(2)SnNO(4) penta-gonal-bipyramidal geometries. Adjacent dinuclear units are linked by O-H?N hydrogen bonds, generating a linear chain, which propagates in the b-axis direction. O-H?O inter-actions are also observed.

Project description:In the title mol-ecule, [Sn(C(7)H(6)Cl)(2)(C(6)H(4)NO(2))(2)(H(2)O)], the O atoms of the two chelating nicotinate groups and the O atom of the coordinated water mol-ecule comprise the penta-gonal plane of the trans-C(2)SnO(5) penta-gonal-bipyramid [C-Sn-C = 178.62?(11) °] surrounding the Sn(IV) atom. In the crystal, adjacent mol-ecules are linked by O-H?N hydrogen bonds, generating a chain running along the body diagonal of the triclinic unit cell.

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.

Di-μ-hydroxido-bis-[aqua-trichlorido-tin(IV)] diethyl ether disolvate.

Project description:The title compound, [Sn(2)Cl(6)(OH)(2)(H(2)O)(2)]·2C(4)H(10)O, consists of a centrosymmetric molecule and two additional solvent molecules and has an infinite two-dimensional network extending parallel to (101). The Sn atom is six-coordinate with a distorted octa-hedral geometry. Additional O-H⋯O hydrogen bonding leads to stabilization of the crystal structure.

Project description:The six-coordinate Sn(IV) atom in the title compound, [Sn(C(8)H(9))Cl(3)(C(3)H(4)N(2))(2)], shows an octa-hedral coordination. The N atoms of the N-heterocycle are cis to each other. The Sn-N bond that is trans to the Sn-C bond is shorter than the Sn-N bond trans to the Sn-Cl bond. Weak N-H?Cl hydrogen bonds link adjacent mol-ecules, generating a double chain running along the c axis.

Dichloridoocta-kis(2-chloro-benz-yl)di-?(2)-hydroxido-di-?(3)-oxido-tetra-tin(IV).

Project description:The title tetra-nuclear Sn(IV) compound, [Sn(4)(C(7)H(6)Cl)(8)Cl(2)O(2)(OH)(2)], has site symmetry . Two O(2-) and two OH(-) anions bridge four Sn(IV) cations to form the tetra-nuclear compound. The two independent Sn(IV) cations assume SnO(3)C(2) and SnO(2)C(2)Cl distorted trigonal-bipyramidal coordination geometries. Intra-molecular O-H?Cl hydrogen bonding is present in the structure. One Cl atom of a chloro-benzyl ligand is disordered over two sites with an occupancy ratio of 0.693?(2):0.307?(2).

Triclinic form of bis-{di-?-hydroxidobis[fac-aqua-tribromido-tin(IV)]} hepta-hydrate.

Project description:The asymmetric unit of the title hydrate, 2[Sn(H(2)O)(2)(OH)(2)Br(6)]·7H(2)O, comprises two [Br(3)(H(2)O)Sn(?-OH)(2)SnBr(3)(OH(2))] units, but three independent mol-ecules as two of these are disposed about inversion centres, and seven water mol-ecules. In common with the monoclinic polymorph [Howie et al. (2005 ?). Inorg. Chim. Acta, 358, 3283-3286], each of the dinuclear species features a central Sn(2)O(2) core, distorted octa-hedral Sn atom geometries defined by a Br(3)O(3) donor set, and an anti-disposition of the coordinated water mol-ecules. In the crystal, O(h)-H?O(w), O(a)-H?O(w), O(w)-H?O(w), and O(w)-H?Br (h = hydroxyl, a = aqua, w = water) hydrogen-bonding inter-actions generate a three-dimensional network.
