ABSTRACT: In the title compound, [Sn(C6H5)3(C2H3OS2)], the Sn(IV) atom adopts a distorted SnC3S tetra-hedral coordination geometry. A short Sn?O contact [2.988?(4)?Å] is also present. The phenyl rings are each disordered over two sets of sites with an occupancy ratio of 0.550?(8):0.450?(8). The crystal studied was found to be a racemic twin with a twin component ratio of 0.57?(18):0.43?(18).

Crystal structures of di-aquadi-?-hydroxido-tris-[tri-methyl-tin(IV)] diformatotri-methyl-stannate(IV) and di-?-hydroxido-tris-[tri-methyl-tin(IV)] chloride monohydrate.

Project description:The title compounds, [Sn3(CH3)9(OH)2(H2O)2][Sn(CH3)3(CHO2)2] (1) and [Sn3(CH3)9(OH)2]Cl·H2O (2), are partially condensed products of hydrolysed tri-methyl-tin chloride. In the structures of 1 and 2, short cationic tris-tannatoxanes (C9H29O2Sn3) are bridged by a diformatotri-methyl-tin anion or a chloride anion, respectively. Hydrogen bridges are present and supposedly stabilize these structures against further polymerization to the known polymeric tri-methyl-tin hydroxide. Especially noteworthy is that the formate present in this structure was formed from atmospheric CO2.

Project description:The crystal and mol-ecular structures of the two title organotin di-thio-carbamate compounds, [Sn(C4H9)2(C7H14NO2S2)2], (I), and [Sn(C6H5)3(C5H10NOS2)], (II), are described. Both structures feature asymmetrically bound di-thio-carbamate ligands leading to a skew-trapezoidal bipyramidal geometry for the metal atom in (I) and a distorted tetra-hedral geometry in (II). The complete mol-ecule of (I) is generated by a crystallographic twofold axis (Sn site symmetry 2). In the crystal of (I), mol-ecules self-assemble into a supra-molecular array parallel to (10-1) via methyl-ene-C-H?O(meth-oxy) inter-actions. In the crystal of (II), supra-molecular dimers are formed via pairs of weak phenyl-C-H??(phen-yl) contacts. In each of (I) and (II), the specified assemblies connect into a three-dimensional architecture without directional inter-actions between them. Hirshfeld surface analyses confirm the importance of H?H contacts in the mol-ecular packing of each of (I) and (II), and in the case of (I), highlight the importance of short meth-oxy-H?H(but-yl) contacts between layers.

Project description:The crystal and mol-ecular structures of two tri-phenyl-tin di-thio-carbamates, [Sn(C6H5)3(C16H16NS2)], (I), and [Sn(C6H5)3(C7H14NO2S2)], (II), are described. In (I), the di-thio-carbamate ligand coordinates the SnIV atom in an asymmetric manner, leading to a highly distorted trigonal-bipyramidal coordination geometry defined by a C3S2 donor set with the weakly bound S atom approximately trans to one of the ipso-C atoms. A similar structure is found in (II), but the di-thio-carbamate ligand coordinates in an even more asymmetric fashion. The packing in (I) features supra-molecular chains along the c axis sustained by C-H?? inter-actions; chains pack with no directional inter-actions between them. In (II), supra-molecular layers are formed, similarly sustained by C-H?? inter-actions; these stack along the b axis. An analysis of the Hirshfeld surfaces for (I) and (II) confirms the presence of the C-H?? inter-actions but also reveals the overall dominance of H?H contacts in the respective crystals.

Di-chlorido-diphenyl-bis-(thio-urea-?S)tin(IV).

Project description:The title compound, [Sn(C6H5)2Cl2(CH4N2S)2], has been obtained from the reaction between Sn(C6H5)2Cl2 and SC(NH2)2. The asymmetric unit consists of one half of the mol-ecular unit, the remainder generated by a twofold rotation axis located along the Cl-Sn-Cl bonds. The Sn(IV) atom is coordinated by two phenyl groups, two Cl atoms and two thio-urea ligands in an all trans octa-hedral C2Cl2S2 environment. Individual mol-ecules are connected through N-H?Cl hydrogen bonds, leading to a three-dimensional network structure. Intra-molecular N-H?Cl hydrogen bonds are also present.

Crystal structures and Hirshfeld surface analyses of (N-hexyl-N-methyl-dithio-carbamato-?2S,S')triphenyl-tin(IV) and [N-methyl-N-(2-phenyl-ethyl)-dithio-carbamato-?2S,S']tri-phenyl-tin(IV).

Project description:The crystal and mol-ecular structures of two tri-phenyl-tin di-thio-carbamate compounds, viz. [Sn(C6H5)3(C8H16NS2)], (I), and [Sn(C6H5)3(C10H12NS2)], (II), are described. The di-thio-carbamate ligand in each mol-ecule coordinates in an asymmetric fashion resulting in heavily distorted tetra-hedral C3S coordin-ation geometries for the Sn atoms, with the distortions traced to the close approach of the non-coordinating thione-S atom. The mol-ecular packing in both compounds features C-H??(Sn-phen-yl) inter-actions. In (I), the donors are Sn-phenyl-C-H groups leading to centrosymmetric aggregates, while in (II), the donors are both Sn-phenyl-C-H and methyl-C-H groups leading to supra-molecular chains propagating along the b axis. The identified aggregates assemble into their respective crystals with no directional inter-actions between them. An analysis of the Hirshfeld surfaces show distinctive patterns, but an overwhelming predominance (>99% in each case) of H?H, C?H/H?C and S?H/H?S contacts on the respective Hirshfeld surface.
