Catena-Poly[[tribenzyl-tin(IV)]-μ-(E)-3-(2-fur-yl)prop-2-enoato-κO:O'].

ABSTRACT: In the title carboxyl-ate-bridged polymer, [Sn(C(7)H(7))(3)(C(7)H(5)O(3))](n), the Sn(IV) atom exists in a distorted trans-C(3)SnO(2) trigonal-bipyramidal geometry. The polymer propagates as a chain along the a axis. There are two independent formula units in the asymmetric unit; the furyl ring of one of the anions is disordered over two positions in a 0.630 (8):0.370 (8) ratio. The crystal studied was a non-merohedral twin with a minor twin domain of 37.3 (1)%.

catena-Poly[[tribenzyl-tin(IV)]-?-(E)-3-phenyl-prop-2-enoato-?O:O'].

Project description:The Sn(IV) atom in the title carboxyl-ate-bridged polymer, [Sn(C(7)H(7))(3)(C(9)H(7)O(2))](n), exists in a trans-C(3)SnO(2) trigonal-bipyramidal geometry (average covalent Sn-O = 2.167?Å, average dative Sn-O = 2.361?Å and average O-Sn-O = 169.6°). The polymer propagates as a helical chain along the b axis with a repeat distance that is half the b-axial length. There are four independent formula units in the asymmetric unit; two are disposed about a false center of inversion with respect to the other two so that the space group emulates a centric space group.

Project description:The 4-nitro-cinnamate anion in the title compound, [Sn(C(7)H(7))(3)(C(9)H(6)NO(4))](n), bridges adjacent tribenzyl-tin cations into a helical chain running along the b axis. The Sn atoms in the two independent mol-ecules adopt distorted trans-C(3)SnO(2) trigonal-bipyramidal geometries. The repeat distance of the polymeric chain is b/2.

catena-Poly[[trimethyl-tin(IV)]-μ-quinaldato].

Project description:The title compound, [Sn(CH(3))(3)(C(10)H(6)NO(2))](n), forms an extended one-dimensional chain structure. There are two independent Sn(IV) ions, both of which are in slightly distorted trigonal-bipyramidal coordination environments with two symmetry-related O atoms in the axial sites. In each case, the Sn(IV) ion and one of the three equatorial C atoms lie on a crystallographic twofold axis.

catena-Poly[[di-tert-butyl-tin(IV)]-μ-oxalato].

Project description:The title compound, [Sn(C4H9)2(C2O4)] n , an unexpected side product in the reaction of di-tert-butyl-tin(IV) oxide with nitric acid, represents the first diorganotin(IV) oxalate to be structurally characterized. The Sn(IV) atom of the one-dimensional coordination polymer is located on a mirror plane and is coordinated by two chelating oxalate ions with two rather different Sn-O bond lengths of 2.150 (1) and 2.425 (1) Å, and two t-butyl groups with Sn-C bond lengths of 2.186 (2) and 2.190 (2) Å. The coordination polyhedron around the Sn(IV) atom is a distorted tetra-gonal disphenoid. The centrosymmetric oxalate ion also has an asymmetric coordination geometry, as reflected by the two slightly different C-O bond lengths of 1.242 (2) and 1.269 (2) Å. The chains of the polymer propagate along the b-axis direction. Only van der Waals inter-actions are observed between the chains.

catena-Poly[[tribenzyl-tin(IV)]-?-2-(piperidin-1-ylcarbothio-ylsulfan-yl)acetato-?O:O'].

Project description:The Sn atom in the title polymeric compound, [Sn(C(7)H(7))(3)(C(8)H(12)NO(2)S(2))](n), exists in a trans-C(3)O(2) trigonal-bipyramidal coordination environment in the two independent formula units. The carboxyl-ate moiety functions in a bridging mode, linking adjacent triorganotin cations into a linear chain running along the shortest axis of the triclinic unit cell; the repeat distance of the polymer is half the a-axial length. In one formula unit, the Sn atom is displaced out of the equatorial plane in the direction of the Sn-O(covalent) bond by 0.093?(4)?Å and in the second mol-ecule, the Sn atom is displaced by 0.105?(4)?Å in the same direction.

Project description:The formyl-meth-oxy-nitro-phenoxide ions in the polymeric title compound, [Sn(C(7)H(7))(3)(C(8)H(6)NO(5))](n), link adjacent triorganotin(IV) cations into linear chains lying close to (101) [Sn-O = 2.1227?(12)?Å and Sn? O = 2.4936?(13)?Å].

Project description:The title compound, [Sn(2)(CH(3)O)(2)Cl(6)(C(3)H(7)NO)(2)], contains two hexa-coordinated Sn(IV) atoms symmetrically bridged by two deprotonated methanol ligands, with an inversion center in the middle of the planar Sn(2)O(2) ring.

The complex mol-ecules are connected by weak C-H⋯Cl hydrogen bonds into a two-dimensional supra-molecular network parallel to (10).

Project description:The title tetra-nuclear complex mol-ecule, [Sn(4)(C(7)H(7))(8)(C(2)H(2)ClO(2))(4)O(2)], has crystallographically imposed inversion symmetry. Each Sn atom has a distorted trigonal-bipyramidal geometry, with the equatorial plane formed by an oxido O atom and two C atoms of two benzyl anions. The configuration of the complex is stabilized by a pair of C-H⋯O hydrogen bonds. In the crystal, complex mol-ecules are linked into zigzag chains along [110] by C-H⋯O hydrogen bonds.
