6-(2-Chloro-benzyl-amino)purinium tetra-chlorido(dimethyl sulfoxide-?O)(nitrosyl-?N)ruthenate(III) monohydrate.

ABSTRACT: The asymmetric unit of the title complex salt, (C(12)H(11)ClN(5))[RuCl(4)(NO)(C(2)H(6)OS)]·H(2)O, contains a 6-(2-chloro-benzyl-amino)purinium cation, a tetra-chlorido(dimethyl sulfoxide)nitro-sylruthenate(III) anion and one solvent water mol-ecule. The Ru(III) atom is octa-hedrally coordinated by four Cl atoms in the equatorial plane, and by a dimethyl sulfoxide O atom and a nitrosyl N atom in axial positions. The cation is an N3-protonated N7 tautomer. Inter-molecular N-H?N hydrogen bonds connect two cations into centrosymmetric dimers, with an N?N distance of 2.821?(4)?Å. The crystal structure also involves N-H?O, N-H?Cl and O-H?Cl hydrogen bonds.

(Dimethyl sulfoxide-κO)bis-(thio-semicarbazide-κN,S)zinc dipicrate dimethyl sulfoxide solvate monohydrate.

Project description:The title complex, [Zn(CH(5)N(3)S)(2)(C(2)H(6)OS)](C(6)H(2)N(3)O(7))(2)·C(2)H(6)OS·H(2)O, is composed of a [Zn(thio-semi-carbazide)(2)(DMSO)](2+) cation (where DMSO is dimethyl sulfoxide), and two picrate anions. In the asymmetric unit, there is also a solvent mol-ecule of DMSO and a water mol-ecule of crystallization. In the cation, the Zn(II) atom is five-coordinated in a distorted square-pyramidal geometry. It coordinates to the O atom of a DMSO mol-ecule and to the S and one N atom of two thio-semicarbazide mol-ecules, which behave as bidentate ligands coordinating in a trans arrangement. In the crystal, a number of N-H⋯O, O-H⋯O and N-H⋯S hydrogen bonds link the mol-ecules into two-dimensional networks. These networks are further linked via weak C-H⋯O inter-actions, forming a three-dimensional arrangement. Positional disorder in one methyl group of the coordinated DMSO molecule and in the two picrate anions was observed.

Chlorido(dimethyl sulfoxide-κO)triphenyl-tin(IV).

Project description:In the title compound, [Sn(C(6)H(5))(3)Cl(C(2)H(6)OS)], the Sn(IV) atom is coordinated by three phenyl groups, a chloride ion and a dimethyl sulfoxide mol-ecule in a distorted trigonal-bipyramidal geometry. In the crystal, adjacent mol-ecules are linked through inter-molecular C-H⋯Cl hydrogen bonds, weak C-H⋯π inter-actions and π-π inter-actions [centroid-centroid distance = 3.934 (3) Å. An intra-molecular C-H⋯π inter-action is also observed.

Bis(chlorido)(dimethyl-sulfoxide-κO)barium(II).

Project description:The title compound, [BaCl(2)(C(2)H(6)SO)], forms a Ba(6)Cl(9) cluster in which the BaCl(2) units are connected via dimethyl-sulfoxide (DMSO) and chloride bridges. The central Cl atom of the Ba(6)Cl(9) cluster is located on a threefold inversion axis and is coordinated octa-hedrally to six barium cations. In the crystal, the clusters are arranged in rows, which are inter-connected by the DMSO mol-ecules, forming a three-dimensional network.

Trichlorido(4,4'-dimethyl-2,2'-bipyridine-κN,N')(dimethyl sulfoxide-κO)indium(III).

Project description:In the mol-ecule of the title compound, [InCl(3)(C(12)H(12)N(2))(C(2)H(6)OS)], the In(III) atom is six-coordinated in a distorted octa-hedral configuration by two N atoms from the chelating 4,4'-dimethyl-2,2'-bipyridine ligand, one O atom from dimethyl sulfoxide and three Cl atoms. In the crystal structure, inter-molecular C-H⋯Cl hydrogen bonds link the mol-ecules into centrosymmetric dimers.

Monoclinic polymorph of chlorido-(dimethyl sulfoxide-κO)tri-phenyl-tin(IV).

Project description:The crystal structure of the title tin complex, [Sn(C6H5)3Cl(C2H6OS)], (I), has been reported with one mol-ecule in the asymmetric unit in an ortho-rhom-bic cell [Kumar et al. (2009 ▸). Acta Cryst. E65, m1602-m1603]. While using SnPh3Cl as a starting material for a reaction for which the products were recrystallized over a very long time (six months) from dimethyl sulfoxide (DMSO), a new polymorph was obtained for (I), with two independent mol-ecules in the asymmetric unit of a monoclinic cell. The coordination geometry of the Sn centres remains unchanged, with the Cl- ion and the DMSO mol-ecule in the apical positions and the phenyl C atoms in the equatorial positions of a trigonal bipyramid. The main difference between the polymorphs is the relative orientation of the phenyl rings in the equatorial plane, reflecting a degree of free rotation of these groups about their Sn-C bonds. In the crystal, mol-ecules are linked into [010] chains mediated by weak C-H⋯O inter-actions.

Crystal structure of chlorido-penta-kis(dimethyl sulfoxide-κO)chromium(III) dichloride.

Project description:In the complex cation of the title salt, [CrCl(C2H6OS)5]Cl2, the Cr(III) ion is coordinated by one chloride ligand and five O atoms from dimethyl sulfoxide (DMSO) ligands, leading to a slightly distorted octa-hedral coordination environment [O-Cr-O angles range from 86.69 (16) to 92.87 (16)°]. In the crystal, complex cations are arranged in hexa-gonally packed rows parallel to [010], with the chloride counter-anions situated in between. The inter-actions between cations and anions are mainly ionic in nature.

trans-Di-chlorido-bis-(dimethyl sulfoxide-κO)bis-(4-fluoro-benzyl-κC1)tin(IV): crystal structure and Hirshfeld surface analysis.

Project description:The SnIV atom in the title diorganotin compound, [Sn(C7H6F)2Cl2(C2H6OS)2], is located on a centre of inversion, resulting in the C2Cl2O2 donor set having an all-trans disposition of like atoms. The coordination geometry approximates an octa-hedron. The crystal features C-H⋯F, C-H⋯Cl and C-H⋯π inter-actions, giving rise to a three-dimensional network. The respective influences of the Cl⋯H/H⋯Cl and F⋯H/H⋯F contacts to the mol-ecular packing are clearly evident from the analysis of the Hirshfeld surface.

(Benzoato-κO)(benzoic acid-κO)(4,4'-dimethyl-2,2'-bipyridine-κN,N')hydroxidocopper(II) monohydrate.

Project description:In the structure of the title complex, [Cu(C(7)H(5)O(2))(OH)(C(12)H(12)N(2))(C(7)H(6)O(2))]·H(2)O, the Cu(II) ion is penta-coordinated in a tetra-gonal-pyramidal geometry with one O atom of a hydroxide group, one O atom of a benzoate anion and two N atoms of a 4,4'-dimethyl-2,2'-bipyridine ligand occupying the basal plane, and one O atom of a benzoic acid mol-ecule located at the apical site. The title complex was refined with a metal-coordinated OH group and a 'free' benzoic acid molecule, although it can be assumed that the proton is delocalized between the OH and the COOH group. The uncoordinated water mol-ecule is equally disordered over two positions. The structure displays O-H⋯O hydrogen bonding.

Aqua-(2,9-dimethyl-1,10-phenanthroline-κN,N')diformato-κO,O';κO-nickel(II) monohydrate.

Project description:The asymmetric unit of the title compound, [Ni(HCO(2))(2)(C(14)H(12)N(2))(H(2)O)]·H(2)O, contains a mononuclear complex mol-ecule hydrogen bonded to a lattice water mol-ecule. The Ni(II) atom exhibits a distorted octa-hedral coordination geometry formed by the N atoms from a 2,9-dimethyl-1,10-phenanthroline ligand, two O atoms of a chelating formate anion, one aqua O atom and one O atom of a coordinating formate anion. The mol-ecules are assembled into chains extending along [100] through by O-H⋯O hydrogen bonds. The supra-molecular chains are further linked into layers parallel to (011) by weak π-π packing inter-actions [centroid-centroid separation = 3.768 (2) Å]. The resulting layers are stacked to meet the requirement of close-packing patterns.
