[1-tert-Butyl-3-(pyridin-2-ylmethyl-κN)imidazol-2-yl-idene-κC]carbonyl-dichlorido(dimethyl sulfoxide-κS)ruthenium(II).

ABSTRACT: 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.

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

Project description: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-?S)(?-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] ?(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.

A new monoclinic polymorph of dichlorido-tetra-kis(dimethyl sulfoxide)-ruthenium(II).

Project description:The title compound, cis,fac-dichloridotetra-kis(dimethyl sulfoxide)-κ(3)S,κO-ruthenium(II), [RuCl(2)(C(2)H(6)OS)(4)], was obtained from newly synthesized ruthenium complexes of 3-amino-2-chloro-pyridine. The Ru atom has a distorted octa-hedral coordination with two cis-oriented chloride ligands and four dimethyl sulfoxide ligands. Three of the sulfoxide ligands are S-bonded in a fac configuration, while the fourth is O-bonded. The title compound represents a new, and fourth, polymorph of the complex. Two other monoclinic forms and an ortho-rhom-bic modification have been reported previously.

Poly[di-?(2)-chlorido-dichlorido(?(3)-di-methyl sulfoxide-?O:O:S)(?(2)-di-methyl sulfoxide-?O:S)ruthenium(III)sodium].

Project description:The structure of the title compound, [NaRuCl(4)(C(2)H(6)OS)(2)](n), comprises centrosymmetric [RuCl(2)(DMSO)Na(DMSO)Cl(2)Ru] units (DMSO is dimethyl sulfoxide, C(2)H(6)OS), with two Ru atoms, each lying on a crystallographic centre of inversion, connected via Na atoms, DMSO and chloride ligands into a two-dimensional (110) array. Both Ru(III) atoms are octa-hedrally coordinated by four chloride ligands in the equatorial plane and by two DMSO mol-ecules in apical positions within a RuCl(4)S(2) donor set. The Na atom is surrounded by three chloride anions and three O atoms derived from three DMSO mol-ecules, with the resulting Cl(3)O(3) donor set defining an octa-hedron. The crystal structure is further stabilized by inter-atomic inter-actions of the types C?Cl [C-Cl = 3.284?(2)?Å], C-H?Cl [C?Cl = 3.903?(3)?Å] and C-H?O [C?O = 3.376?(3)?Å].

Tris(tert-butyl isocyanide-κC)carbonylnickel(0).

Project description:The title compound, [Ni(C(5)H(9)N)(3)(CO)], was prepared from Ni(CO)(4) and a tenfold excess of tert-butyl isocyanide. It crystallizes with two symmetry-independent mol-ecules per asymmetric unit. The central Ni atom of each independent mol-ecule has a nearly perfect tetra-hedral coordination environment, comprising one carbon monoxide and three isocyanide ligands. The title compound is the first structurally characterized Ni(0) compound with a mixed CO/RNC coordination.

cis,fac-Dichlorido{N-[3,5-di-tert-butyl-2-(trimethyl-silyl-oxy)benz-yl]-N,N-bis-(2-pyridylmeth-yl)amine}(dimethyl sulfoxide)ruthenium(II) dichloro-methane disolvate.

Project description:Reaction of dichloridotetra-kis(dimethyl sulfoxide)ruthenium(II) and N-[3,5-di-tert-butyl-2-(trimethyl-silyl-oxy)benz-yl]-N,N-bis-(2-pyridylmeth-yl)amine (BPPA-TMS) affords the thermodynamic product cis,fac-[RuCl(2)(BPPA-TMS)(DMSO)] and kinetic product trans,mer-[RuCl(2)(BPPA-TMS)(DMSO)]. The title complex, [RuCl(2)(C(30)H(43)N(3)OSi)(C(2)H(6)OS)]·2CH(2)Cl(2), crystallizes as a dichloro-methane disolvate, with two formula units in the asymmetric unit. The complex exhibits a distorted-octa-hedral geometry about the low spin d(6) Ru(II) center. The BPPA-TMS ligand is coordinated in a facial fashion, with the DMSO ligand cis to the aliphatic nitro-gen atom of the BPPA-TMS ligand. One of the two dichloromethane solvate molecules is disordered over two positions in a 0.695:0.305 ratio.

Dichlorido[1-(2-chloro-eth-yl)-3-(pyridin-4-ylmethyl-?N)urea](?-hexa-methyl-benzene)-ruthenium(II) chloro-form monosolvate.

Project description:The Ru(II) atom in the title compound, [RuCl(2)(C(12)H(18))(C(9)H(12)ClN(3)O)]·CHCl(3), exhibits a typical piano-stool coordination, defined by a hexa-methyl-benzene ligand, two chloride ligands and a pyridyl-urea ligand coordinated through the pyridine N atom. In the crystal, a dimeric structure is observed due to two strong N-H?Cl inter-actions between the NH groups of urea and the two chloride ligands of neighbouring mol-ecules. In addition, the C=O group of the urea moiety inter-acts with the solvent mol-ecule through weak C-H?O interactions.

Bis[μ-1,2-bis-(1H-imidazol-1-ylmethyl)benzene-κN:N]disilver(I) bis-(4-amino-2,5-dichloro-benzene-sulfonate) tetra-hydrate.

Project description:The asymmetric unit of the title compound, [Ag(2)(C(14)H(14)N(4))(2)](C(6)H(4)Cl(2)NO(3)S)(2)·4H(2)O, contains one-half of each of two independent dicationic units, two 4-amino-2,5-dichloro-benzene-sulfonate anions and four water mol-ecules. Each centrosymmetric dicationic unit has a dinuclear structure in which two Ag(I) atoms are bridged by two 1,2-bis-(1H-imidazol-1-yl-meth-yl)benzene ligands in a slightly distorted linear coordination geometry. The 4-amino-2,5-dichloro-benzene-sulfonate anion does not coordinate with the Ag(I) center, acting only as a counteranion. In the crystal structure, inter-molecular O-H⋯O and N-H⋯O hydrogen bonds form a three-dimensional network.

Poly[bis-(acetonitrile-κN)di-μ-thio-cyanato-κN,S;κS,N-nickel(II)].

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.

Project description:The asymmetric unit of the title compound [Mn(NCS)(2)(C(9)H(13)N)(4)] consists of one Mn(II) cation located on a center of inversion, one thio-cyanato anion, one 3-tert-butyl-pyridine ligand and one 4-tert-butyl-pyridine ligand in general positions. The tert-butyl group of the 4-tert-butyl-pyridine ligand is disordered over two sets of sites in a 0.60:0.40 ratio. The Mn(II) cation is coordinated by six N atoms of four tert-butyl-pyridine ligands and two N-bonded thio-cyanato anions within a slightly distorted octa-hedral coordination environment.
