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

ABSTRACT: 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.

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.

Dipotassium disulfanilamidate trihydrate.

Project description:The asymmetric unit of the title compound, 2K(+)·2C(6)H(7)N(2)O(2)S(-)·3H(2)O, consists of two potassium cations located on mirror planes, one sulfanilamidate anion in a general position and one and a half mol-ecules of water, one of which is also located on a mirror plane. One potassium cation is seven-coordinated by six sulfonyl O atoms and one water mol-ecule, whereas the other is surrounded by six water O atoms and two sulfonyl O atoms. In the crystal structure, the components are connected into polymeric sheets in the bc plane. The two-dimensional structure is consolidated by N-H?O, O-H?O, O-H?N and C-H?? inter-actions. The layers are further linked into a three-dimensional network via N-H?O, N-H?N and O-H?N hydrogen bonds.

Crystal structure of benzyl (E)-2-(3,4-di-meth-oxy-benzyl-idene)hydrazine-1-carbodi-thio-ate.

Project description:The title compound, C17H18N2O2S2, synthesized via a condensation reaction between S-benzyl di-thio-carbazate and 3,4-di-meth-oxy-benzaldehyde, crystallized with two independent mol-ecules (A and B) in the asymmetric unit. Both mol-ecules have an L-shape but differ in the orientation of the benzyl ring with respect to the 3,4-di-meth-oxy-benzyl-idine ring, this dihedral angle is 65.59?(8)° in mol-ecule A and 73.10?(8)° in mol-ecule B. In the crystal, the A and B mol-ecules are linked via pairs of N-H?S hydrogen bonds, forming dimers with an R 2 (2)(8) ring motif. The dimers are linked via pairs of C-H?O hydrogen bonds, giving inversion dimers of dimers. These units are linked by C-H?? inter-actions, forming ribbons propagating in the [100] direction.

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].

Secondary bonding in di-methyl-bis-(morpholine-4-carbodi-thio-ato-κ2S,S')tin(IV): crystal structure and Hirshfeld surface analysis.

Project description: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 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.

Tris-(?4-azepane-1-carbodi-thio-ato)bis-(?3-azepane-1-carbodi-thio-ato)-?9-bromido-tetra-?2-bromido-octa-copper(I)-copper(II).

Project description:The reaction of Cu(Hm-dtc)2 (H2m-dtc is azepane-1-carbodi-thioic acid), CuBr2 and methyl iso-thio-cyanate yielded the title mixed-valence nona-nuclear Cu(I)/Cu(II) compound, [Cu9Br5(C7H12NS2)5] or [Cu(I) 8Cu(II)Br5(Hm-dtc)5], encapsulating a bromide anion in the center of the Cu9Br4S10 cluster cage. The cage consists of a mononuclear Cu(II) unit [Cu(Hm-dtc)2], three ?4-bridging Hm-dtc(-) ligands, eight Cu(I) ions with distorted tetra-hedral or trigonal pyramidal coordination geometries and four ?2-bridging bromide anions. The incorporated central bromide anion inter-acts with nine Cu ions with shorter Cu-Br separations than the sum of the van der Waals radii for Cu and Br.

Crystal structure of 1,3-di-cyclo-hexyl-4,5-dimethyl-1H-imidazol-3-ium-2-carbodi-thio-ate chloro-form monosolvate.

Project description:The title compound, C18H28N2S2·CHCl3, crystallizes as a zwitterion. The C-S bonds are almost equivalent, with lengths of 1.666?(3) and 1.657?(3)?Å. The S-C-S bond angle is expanded to 129.54?(16)° and the N-C-N angle is reduced to the tetra-hedal value of 108.8?(2)°. In the crystal, adjacent mol-ecules are linked via C-H?S hydrogen bonds, forming chains along [100]. The chloro-form solvent mol-ecule, which is disordered over two positions [occupancy ratio = 0.51?(2):0.49?(2)], is linked to the chain by bifurcated C-H?(S,S) hydrogen bonds.

Crystal structure of penta-carbon-yl(2,2-di-fluoro-propane-thio-ato-κS)manganese(I).

Project description:The title compound, [Mn{SC(O)CF2CH3}(CO)5], has been isolated as a by-product during the reaction of K[Mn(CO)5] with CH3CF2COCl. It is built up from a di-fluoro-methyl-propane-thio-ate bonded to an Mn(CO)5 moiety through the S atom. The Mn atom has an almost perfect octa-hedral coordination sphere. It is one of the rare examples of compounds containing the (CO)5MnS-C fragment. In the crystal, the methyl group occupies a pocket surrounded by the O atoms of three carbonyl groups of the Mn(CO)5 moiety; however, the H⋯O distances are rather long. These inter-actions lead to the formation of layers lying parallel to (101), which enclose R 4 4(15) and R 4 4(16) ring motifs. The CF2 group is disordered over two sets of sites with occupancies of 0.849 (3) and 0.151 (3).
