Secondary bonding in di-methyl-bis-(morpholine-4-carbodi-thio-ato-?²S,S')tin(IV): crystal structure and Hirshfeld surface analysis.

ABSTRACT: The title compound, [Sn(CH₃)₂(C₅H₈NOS₂)₂], has the Sn^IV atom bound by two methyl groups which lie over the weaker Sn-S bonds formed by two asymmetrically chelating di-thio-carbamate ligands so that the coordination geometry is skew-trapezoidal bipyramidal. The most prominent feature of the mol-ecular packing are secondary Sn?S inter-actions [Sn?S = 3.5654?(7)?Å] that lead to centrosymmetric dimers. These are connected into a three-dimensional architecture via methyl-ene-C-H?S and methyl-C-H?O(morpholino) inter-actions. The Sn?S inter-actions are clearly evident in the Hirshfeld surface analysis of the title compound along with a number of other inter-molecular contacts.

The title compound, [Sn(CH3)2(C5H8NOS2)2], has the SnIV atom bound by two methyl groups which lie over the weaker Sn-S bonds formed by two asymmetrically chelating di-thio-carbamate ligands so that the coordination geometry is skew-trapezoidal bipyramidal. The most prominent feature of the mol-ecular packing are secondary Sn⋯S inter-actions [Sn⋯S = 3.5654 (7) Å] that lead to centrosymmetric dimers. These are connected i ...[more]

Triphen-yl(pyrrolidine-1-carbodi-thio-ato-?S)tin(IV).

Project description:In the title compound, [Sn(C6H5)3(C5H8NS2)], the Sn(IV) atom adopts a distorted SnC3S tetra-hedral coordination geometry [spread of bond angles = 94.43?(7)-120.74?(7)°]. A short intra-molecular Sn?S contact [3.0270?(9)?Å] occurs and two intra-molecular C-H?S inter-actions help to establish the conformation. Three of the methyl-ene groups of the pyrrolidine-1-carbodi-thio-ate ligand are disordered over two sets of sites of equal occupancy. In the crystal, very weak C-H?S inter-actions link the mol-ecules into a three-dimensional network, with both S atoms acting as acceptors.

Project description:In the title compound, [Sn(2)(CH(3))(6)(C(6)H(2)O(4)S)(H(2)O)](n), each of the two crystallographically independent Sn atoms exhibits a distorted trigonal-bipyramidal coordination geometry formed by two O and three C atoms. The coordinated water mol-ecule plays an important role in crystal packing consolidation via O-H?O hydrogen bonding.

Bis{4-methylbenzyl 2-[4-(propan-2-yl)benzyl-idene]hydrazine-carbodi-thio-ato-κ2N2,S}nickel(II): crystal structure and Hirshfeld surface analysis.

Project description:The complete mol-ecule of the title hydrazine carbodi-thio-ate complex, [Ni(C19H21N2S2)2], is generated by the application of a centre of inversion. The NiII atom is N,S-chelated by two hydrazinecarbodi-thio-ate ligands, which provide a trans-N2S2 donor set that defines a distorted square-planar geometry. The conformation of the five-membered chelate ring is an envelope with the NiII atom being the flap atom. In the crystal, p-tolyl-C-H⋯π(benzene- i Pr), i Pr-C-H⋯π(p-tol-yl) and π-π inter-actions [between p-tolyl rings with inter-centroid distance = 3.8051 (12) Å] help to consolidate the three-dimensional architecture. The analysis of the Hirshfeld surface confirms the importance of H-atom contacts in establishing the packing.

Project description:In the title polymeric coordination compound, [Sn(CH(3))(3)(C(6)H(5)O(2)S)](n), which contains two formula units in the asymmetric unit, the Sn(IV) atom has a distorted trigonal-bipyramidal geometry, with two O atoms of the ligands in axial positions and three methyl groups in equatorial positions. Adjacent Sn(IV) atoms are bridged by the ligands, thereby forming a chain propagating in [010].

Crystal structure of dipotassium N-carbodi-thio-ato-l-prolinate trihydrate.

Project description:The mol-ecular and crystal structure of the l-proline-derived di-thio-carbamate-carboxyl-ate compound poly[tri-?-aqua-(?-2-carboxyl-atopyrrolidine-1-carbodi-thio-ato)dipotassium], [K2(C6H7NO2S2)(H2O)3] n or K2(SSC-NC4H7-COO)·3H2O, has been determined. The di-thio-carbamate moiety displays a unique coordination mode, comprising a 'side-on' ?-coordinated K+ cation besides a commonly ?-chelated K+ cation. By bridging coordination of the CSS group, COO group and water mol-ecules, the K+ cations are linked into a two-dimensional coordination polymer extending parallel to the ab plane. These layers are again inter-connected by O-H?S hydrogen bonds.

Crystal structure of (6-bromo-2-oxo-2H-chromen-4-yl)methyl morpholine-4-carbodi-thio-ate.

Project description:In the title compound, C15H14BrNO3S2, the 2H-chromene ring system is nearly planar, with a maximum deviation of 0.034 (2) Å, and the morpholine ring adopts a chair conformation. The dihedral angle between best plane through the 2H-chromene ring system and the morpholine ring is 86.32 (9)°. Intra-molecular C-H⋯S hydrogen bonds are observed. In the crystal, inversion-related C-H⋯S and C-H⋯O inter-actions generate R 2 (2)(10) and R 2 (2)(8) rings patterns, respectively. In addition, the crystal packing features π-π inter-actions between fused benzene rings [centroid-centroid distance = 3.7558 (12) Å].

[N-Benzyl-N-(2-phenyl-eth-yl)di-thio-carbamato-?2S,S']tri-phenyl-tin(IV) and [bis-(2-meth-oxy-eth-yl)di-thio-carbamato-?2S,S']tri-phenyl-tin(IV): crystal structures and Hirshfeld surface analysis.

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.

Project description:In the title salt, [Sn(CH(3))(2)Cl(CH(4)N(3)S)]Cl, the Sn(IV) atom is five-coordinated in a distorted trigonal-bipyramidal geometry with two methyl groups and one S atom in the equatorial plane, and one N atom and one Cl atom occupying the apical positions. In the crystal, mol-ecules are linked by inter-molecular N-H?S hydrogen bonds with set graph-motif C(4) along [010]. N-H? Cl hydrogen bonds with graph-set motif D(2) and D(3) (3)(10) link cations and anions.
