(Acridine-κN)(dimethyl sulfoxide-κS)diiodidoplatinum(II).

ABSTRACT: In the title complex, [PtI(2)(C(13)H(9)N)(C(2)H(6)OS)], the Pt(II) atom is four-coordinated in an essentially square-planar environment defined by the N atom of the acridine ligand, the S atom of dimethyl sulfoxide, and two iodide ions. The dihedral angle between the nearly planar PtI(2)NS unit [maximum deviation = 0.083 (2) Å] and the acridine ligand [maximum deviation = 0.038 (6) Å] is 89.29 (7)°. In the crystal structure, the complex mol-ecules are arranged in a V-shaped packing pattern along the c axis and linked by inter-molecular C-H⋯O contacts into supra-molecular chains. There are also several inter-molecular π-π inter-actions between the six-membered rings, with a shortest ring centroid-centroid distance of 3.804 (5) Å.

Dichlorido(dimethyl sulfoxide-κS)(η-mesitylene)ruthenium(II).

Project description:The title compound, [RuCl(2)(C(9)H(12))(C(2)H(6)OS)], features a planar [maximum deviation = 0.0075 (17) Å] η(6)-bound mesitylene ligand and a dimethyl sulfoxide ligand coordinated via the S atom. The overall complex geometry about the Ru(II) atom is best described as a piano-stool configuration.

Project description:In the title complex, [RuCl(2)(C(13)H(17)N(3))(C(2)H(6)OS)(CO)], the coordination environment around the Ru atom is slightly distorted octa-hedral. The Cl atoms are mutually trans to the dimethyl sulfoxide ligand and the imidazole carbene C atom, respectively. The carbonyl ligand is located trans to the pyridine N atom.

Bis(acridine-κN)dibromidoplatinum(II).

Project description:In the title complex, [PtBr(2)(C(13)H(9)N)(2)], the Pt(II) ion is four-coordinated in a slightly distorted square-planar environment by two N atoms from two acridine ligands and two Br atoms. The Pt atom is located on an inversion centre, and thus the asymmetric unit contains one half of the complex and the PtN(2)Br(2) unit is exactly planar. The dihedral angle between the PtN(2)Br(2) unit and acridine ligand is 78.98 (9)°. In the crystal structure, the complex mol-ecules are arranged in two distinct chains along [110] and [10]. In the chains, inter-molecular π-π inter-actions between the pyridyl and benzene rings connect the complex mol-ecules, with a centroid-centroid distance of 3.631 (4) Å.

(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.

Bis(2,2'-bi-1H-imidazole-κN,N)bis-(dimethyl sulfoxide-κO)copper(II) bis-(tetra-fluoridoborate).

Project description:In the title copper(II) salt, [Cu(C(6)H(6)N(4))(2)(C(2)H(6)OS)(2)](BF(4))(2), the Jahn-Teller distorted octa-hedral coordination sphere of copper is formed from four 2,2'-bi-1H-imidazole N atoms and two dimethyl sulfoxide O atoms. The Cu atom lies on a center of inversion. N-H⋯O and N-H⋯F hydrogen bonds give rise to a one-dimensional structure. The BF(4) (-) anion is disordered over two sites in a 0.671 (10):0.329 (10) ratio.

Bis[2-(1H-pyrazol-3-yl-κN)pyridine-κN]dithio-cyanato-κN,κS-cadmium(II).

Project description:The mol-ecular structure of the mononuclear complex, [Cd(SCN)(2)(C(8)H(7)N(3))(2)], contains a Cd(II) atom in a distorted octa-hedral coordination defined by five N atoms from two bidentate chelate 2-(1H-pyrazol-3-yl)pyridine ligands and by one SCN(-) anion. The second SCN(-) anion provides its S atom for completion of the coordination sphere. The complex is linked to four others by N-H⋯N and N-H⋯S hydrogen-bonding inter-actions between the pyrazol N-H group and the terminal S and N atoms of neighbouring SCN(-) anions. This arrangement leads to the formation of sheets parallel to (100). Face-to-face π-π stacking inter-actions with shortest inter-planar distances of 3.805 (2) and 3.696 (2) Å help to consolidate the crystal packing.

Project description:In the title compound, [Ni(NCS)(2)(CH(3)CN)(2)](n), the Ni(II) cation is coordinated by two N-bonded and two S-bonded thio-cyanate anions, as well as two acetonitrile mol-ecules in an octa-hedral NiN(4)S(2) coordination mode. The asymmetric unit comprises one nickel cation, two thio-cyanate anions and two actonitrile mol-ecules. In the crystal, the Ni(II) cations are connected by bridging thio-cyanate anions into a three-dimensional coordination network.
