Tris(aceto-nitrile-?N)dichlorido(tri-phenyl-phosphane-?P)ruthenium(II) aceto-nitrile monosolvate.

ABSTRACT: In the title complex, [RuCl2(CH3CN)3(C18H15P)]·CH3CN, the coordination geometry of the Ru(II) atom is distorted octa-hedral, defined by one P atom from a tri-phenyl-phosphane ligand, three N atoms from three aceto-nitrile ligands and two Cl atoms. The three acetronitile ligands linearly bind to the Ru(II) atom, with Ru-N-C angles of 172.6?(2), 179.9?(2) and 171.4?(2)°.

Tetra-aceto-nitrile-lithium tetra-iso-thio-cyanato-borate.

Project description:The crystal structure of the title salt, [Li(CH3CN)4][B(NCS)4], is composed of discrete cations and anions. Both the Li and B atoms show a tetra-hedral coordination by four equal ligands. The aceto-nitrile and iso-thio-cyanate ligands are linear. The bond angles at the B atom are close to the ideal tetra-hedral value [108.92?(18)-109.94?(16)°], but the bond angles at the Li atom show larger deviations [106.15?(17)-113.70?(17)°].

(?(6)-Benzene)-dichlorido-(chloro-dicyclo-hexyl-phosphane-?P)ruthenium(II) chloro-form monosolvate.

Project description:The title compound, [RuCl2(?(6)-C6H6)(C12H22ClP)]·CHCl3, was prepared by reaction of [RuCl2(?(6)-C6H6)]2 with chloro-dicyclo-hexyl-phosphane in CHCl3 at 323?K under argon. The Ru(II) atom is surrounded by one arene ligand, two Cl atoms and a phosphane ligand in a piano-stool geometry. The phosphane ligand is linked by the P atom, with an Ru-P bond length of 2.3247?(4)?Å. Both cyclo-hexyl rings at the P atom adopt a chair conformation. In the crystal, the Ru(II) complex mol-ecule and the chloro-form solvent mol-ecule are linked by a bifurcated C-H?(Cl,Cl) hydrogen bond. Intra-molecular C-H?Cl hydrogen bonds are also observed.

Tetra-kis(aceto-nitrile)copper(I) hydrogen oxalate-oxalic acid-aceto-nitrile (1/0.5/0.5).

Project description:In the title compound, [Cu(CH3CN)4](C2HO4)·0.5C2H2O4·0.5CH3CN, the Cu(I) ion is coordinated by the N atoms of four aceto-nitrile ligands in a slightly distorted tetra-hedral environment. The oxalic acid mol-ecule lies across an inversion center. The aceto-nitrile solvent mol-ecule is disordered across an inversion center and was refined with half occupancy. In the crystal, the hydrogen oxalate anions and oxalic acid mol-ecules are linked via O-H?O hydrogen bonds, forming chains along [010].

Crystal structure of di-?-iodido-bis-[bis(aceto-nitrile-?N)copper(I)].

Project description:The title compound, [Cu2I2(CH3CN)4], exhibits a centrosymmetric Cu2I2 core [Cu?Cu distance = 2.7482?(11)?Å], the Cu(I) atoms of which are further coordinated by four mol-ecules of aceto-nitrile. The Cu(I) atom has an overall distorted tetra-hedral coordination environment evidenced by L-Cu-L angles (L = N or I) ranging from 100.47?(10) to 117.06?(2)°. The coordination geometries of the aceto-nitrile ligands deviate slightly from linearity as shown by Cu-N-C angles of 167.0?(2) and 172.7?(2)°. In the crystal, there are no significant hydrogen-bonding inter-actions present, so the crystal packing seems to be formed predominantly by van der Waals forces.

Crystal structure of (2,11-di-aza-[3.3](2,6)pyridino-phane-? (4) N,N',N'',N''')(1,6,7,12-tetra-aza-perylene-? (2) N (1),N (12))ruthenium(II) bis-(hexa-fluorido-phosphate) aceto-nitrile 1.422-solvate.

Project description:In the title compound, [Ru(C14H16N4)(C16H8N4)](PF6)2·1.422CH3CN, discrete dimers of complex cations, [Ru(L-N4H2)tape](2+) are formed {L-N4H2 = 2,11-di-aza-[3.3](2,6)pyridino-phane; tape = 1,6,7,12-tetra-aza-perylene}, held together by ?-? stacking inter-actions via the tape ligand moieties with a centroid-centroid distance of 3.49?(2)?Å, assisted by hydrogen bonds between the non-coordinating tape ligand ?,?'-di-imine unit and the amine proton of a 2,11-di-aza-[3.3](2,6)-pyridino-phane ligand of the opposite complex cation. The combination of these inter-actions leads to an unusual nearly face-to-face ?-? stacking mode. Additional weak C-H?N, C-H?F, N-H?F and P-F??-ring (tape, py) (with F?centroid distances of 2.925-3.984?Å) inter-actions are found, leading to a three-dimensional architecture. The Ru(II) atom is coordinated in a distorted octa-hedral geometry, particularly manifested by the Namine-Ru-Namine angle of 153.79?(10)°. The counter-charge is provided by two hexa-fluorido-phosphate anions and the asymmetric unit is completed by aceto-nitrile solvent mol-ecules of crystallization. Disorder was observed for both the hexa-fluorido-phosphate anions as well as the aceto-nitrile solvate mol-ecules, with occupancies for the major moieties of 0.801?(6) for one of the PF6 anions, and a shared occupancy of 0.9215?(17) for the second PF6 anion and a partially occupied aceto-nitrile mol-ecule. A second CH3CN mol-ecule is fully occupied, but 1:1 disordered across a crystallographic inversion center.

Crystal structure of aceto-nitrile-[?(6)-1-methyl-4-(1-methyl-eth-yl)benzene][1-(pyrimidin-2-yl)-3H-indol-1-ium-2-yl-?(2) N,C]ruthenium(II) bis-(hexa-fluorido-anti-monate).

Project description:In the title compound, [Ru(C10H14)(C12H9N3)(CH3CN)][SbF6]2, the ruthenium(II) cation is ? (6)-coordinated by the para-cymene ligand with a Ru-centroid(? (6)-benzene) distance of 1.746?(2)?Å. Furthermore, ruthenium coordinations to the C and N atoms of the pyrimidyl indole ligand are found to be 1.986?(4) and 2.082?(3)?Å, respectively. The typical piano-stool coordination environment is saturated with an aceto-nitrile solvent mol-ecule with a Ru-N distance of 2.044?(3)?Å. The indolyl ligand is protonated at the C3 position with the N=C imine bond length appropriate to that of related 3H-indole-based complexes. In the crystal, the complex cation is linked to the SbF6 (-) ions through weak C-H?F hydrogen bonds.

cis-Bis(O-methyl-dithio-carbonato-?(2) S,S')bis-(tri-phenyl-phosphane-?P)ruthenium(II).

Project description:In the title compound, [Ru(CH3OCS2)2(C18H15P)2], the Ru(II) atom is in a distorted octa-hedral coordination by two xanthate anions (CH3OCS2) and two tri-phenyl-phosphane (PPh3) ligands. Both bidentate xanthate ligands coordinate the Ru(II) atom with two slightly different Ru-S bond lengths but with virtually equal bite angles [71.57?(4) and 71.58?(3)°]. The packing of the complexes is assured by C-H?O and C-H?? inter-actions.

Project description:In the title compound, [Ag2(C3H6N2S)4(C18H15P)2](C2H3O2)2·[Ag(C2H3O2)(C3H6N2S)(C18H15P)2]2·2C2H3N·4H2O, the Ag(I) ion in the mononuclear neutral complex exhibits a distorted tetra-hedral environment with coordination by two P atoms from tri-phenyl-phosphane (PPh3) ligands, one S atom of an imidazolidine-2-thione (etu) ligand and one O atom of an acetate anion. The binuclear cationic complex comprises two inversion-related [Ag(C3H6N2S)2(C18H15P)] units with Ag(I) ions bridged by two S atoms from etu ligands forming a four-membered Ag-S-Ag-S ring. Each Ag(I) ion is coordinated by a P atom of a PPh3 ligand, two S atoms of bridging etu ligands and the terminal S atom of an etu ligand in a distorted tetra-hedral environment. In the crystal, the mononuclear complex is linked to lattice water mol-ecules through O-H?O and N-H?O hydrogen bonds, forming a chain along [100]. In addition, the binuclear complex mol-ecules are connected to acetate anions and lattice water mol-ecules via O-H?O, N-H?O and O-H?S hydrogen bonds, also along [100].
