Tetra-kis(triphenyl-phosphane-κP)silver(I) trifluoro-methane-sulfonate dichloro-methane monosolvate.

ABSTRACT: In the title compound, [Ag(C(18)H(15)P)(4)]CF(3)O(3)S·CH(2)Cl(2), the Ag atom is coordinated by four P atoms from four PPh(3) ligands. The P-Ag-P angles are in the range 108.02 (6)-110.15 (6)°, which confirms the distorted tetra-hedral environment around the Ag atom.

Tetra-kis(triphenyl-phosphane-?P)silver(I) trifluoro-acetate ethanol monosolvate.

Project description:In the title solvated salt, [Ag(C18H15P)4](CF3CO2)·C2H5OH, the Ag(I) atom is coordinated by four P atoms from triphenyl-phosphane ligands in a distorted tetra-hedral geometry. The anion and solvent are engaged in weak O-H?O hydrogen bonds. Of the four triphenyl-phosphane ligands, two each have an equally disordered phenyl ring while the Ag(I) atom is disordered over two positions in a 0.9595?(15):0.0405?(15) ratio and the trifluoro-acetate anion is equally disordered over two positions with respect to the lattice ethanol mol-ecule.

(Ferrocenyl-thio-phospho-nato-κS)(triphenyl-phosphane-κP)gold(I) dichloro-methane monosolvate.

Project description:In the title compound, [AuFe(C(5)H(5))(C(5)H(5)O(2)PS)(C(18)H(15)P)]·CH(2)Cl(2), the two-coordinate gold(I) atom shows a slightly distorted linear arrangement, with a P-Au-S bond angle of 176.81 (6)°. The difference in P=O and P-O(H) bond lengths, which are 1.503 (6) and 1.541 (5) Å, respectively, implies there is apparently no delocalization between the P-O bonds, and the proton appears to be localized on one O atom only. In the crystal structure, inter-molecular O-H⋯O hydrogen bonds link dinuclear mol-ecules into chains propagated in the [010] direction. The dichloro-methane solvent mol-ecule was disordered between two positions in a 0.63 (3):0.37 (3) ratio.

(1,10-Phenanthroline-κN,N')(triphenyl-phosphine-κP)silver(I) trifluoro-methane-sulfonate.

Project description:The structure of the title complex, [Ag(C(12)H(8)N(2))(C(18)H(15)P)]CF(3)SO(3), is based on a distorted trigonal-planar N(2)P coordination of the Ag(I) ion, provided by two N atoms of the bidentate phenanthroline ligand and one P atom of the triphenyl-phosphine ligand. The phenanthroline ligand and one phenyl ring of the triphenyl-phosphine ligand almost lie in one plane (maximum deviation = 0.014 Å from the best planes). The crystal structure may be stabilized by an inter-molecular C-H⋯O hydrogen bond between the phenanthroline ligand and the O atom of the trifluoro-methane-sulfonate anion.

Bis[dicyclo-hexyl-(phenyl)-phosphane-κP]silver(I) perchlorate dichloro-methane monosolvate.

Project description:In the title compound, [Ag{P(C(6)H(11))(2)(C(6)H(5))}(2)]ClO(4)·CH(2)Cl(2), the Ag(I) atom in the mononuclear complex cation is coordinated by two P atoms of the phosphane ligands [Ag-P = 2.3993 (4) and 2.4011 (4) Å; P-Ag-P = 177.473 (18)°] and the perchlorate anion acts as the counter-anion. There is an Ag⋯O(perchlorate) inter-action of 2.873 (2) Å, which contributes to the slightly non-linear bond angle about the Ag(I) atom. Weak inter-molecular C-H⋯O hydrogen-bonding inter-actions involving phenyl, cyclo-hexyl and dichloro-methane H-atom donors and perchlorate O-atom acceptors contribute to the stabilization of the crystal structure.

Bromidotris(triphenyl-phosphane)silver acetonitrile monosolvate monohydrate.

Project description:In the title compound, [AgBr(C(18)H(15)P)(3)]·C(2)H(3)N·H(2)O, the coordination of the Ag atom is close to ideal tetra-hedral, with the three Ag-P bond lengths almost equal [2.5441 (10), 2.5523 (9) and 2.5647 (10) ° A] and the Ag-Br bond slightly longer [2.7242 (5) Å]. The coordination tetra-hedron is slightly flattened, the Ag atom is closer to the PPP plane; the P-Ag-P angles are wider than the Br-Ag-P angles. The voids in the crystal structure are filled with ordered acetonitrile solvent mol-ecules. The remaining electron density was inter-preted as a water mol-ecule, disordered over three alternative positions. Neither of the solvent mol-ecules is connected by any directional specific inter-actions with the complex.

trans-Dichloridobis{tris-[4-(trifluoro-methyl)phen-yl]phosphane-?P}palla-dium(II) dichloro-methane monosolvate.

Project description:The title compound, [PdCl2(C21H12F9P)2]·CH2Cl2, crystallizes with two independent complex molecules (each having the Pd(II) atom situated on an inversion centre) and a dichloro-methane molecule in the asymmetric unit. The independent Pd(II) atoms are in perfectly linear orientations of the ligands in mutually trans positions, but distortions of the Cl-Pd-P angles ranging from 86.151?(19) to 93.849?(19)° are evident. The effective cone angles for the tris-[4-(trifluoro-meth-yl)phen-yl]phosphane ligand were calculated to be 159 and 161°. In the crystal, weak C-H?Cl/F inter-actions create a three-dimensional supramolecular network. Loose packing at two of the -CF3 groups resulted in large thermal vibrations which were treated as two-component disorders [occupancy ratios 0.50:0.50 and 0.628?(15):0.372?(15)].

Tetra-kis(triphenyl-phosphane-?P)silver(I) tetra-fluorido-borate.

Project description:The title complex, [Ag(C(18)H(15)P)(4)]BF(4), was prepared by the reaction of silver(I) tetra-fluorido-borate and triphenyl-phosphane in the presence of 1,2-bis-(pyridin-2-yl)ethyl-ene. The Ag(I) atom is tetra-hedrally coordinated by four P atoms from triphenyl-phosphane (PPh(3)) ligands. Due to symmetry, the tetra-fluorido-borate anion is disordered over three positions (each with one third occupancy). The tetra-fluorido-borate anion does not coordinate to the Ag(I) atom.

(4-Methoxy-benzoyl-meth-yl)triphenyl-phospho-nium trifluoro-methane-sulfonate.

Project description:Colourless crystals of the title compound, C(27)H(24)O(2)P(+)·CF(3)SO(3) (-), have been prepared by the addition of a solution of AgCF(3)SO(3) in methanol to a solution of (4-methoxy-benzoyl-meth-yl)triphenyl-phospho-nium bromide in dry methanol. There are two crystallographically independent mol-ecules in the asymmetric unit. The crystal structure is stabilized by inter- and intra-molecular C-H?O hydrogen bonds and further stabilized by C-H?? inter-actions.

Tetra-kis(4-cyano-pyridine)-palladium(II) bis-(trifluoro-methane-sulfonate).

Project description:The title salt, [Pd(C(6)H(4)N(2))(4)](CF(3)SO(3))(2), comprises Pd(4-cyano-pyridine)(4) dications balanced by two trifluoro-methane-sulfonate anions. The Pd(II) atom lies in a square-planar geometry defined by four N atoms which form equivalent Pd-N inter-actions. The 4-cyano-pyridine ligands are twisted out of the N(4) plane, forming dihedral angles ranging from 66.5?(2) to 89.9?(2)°. In the crystal packing, columns of edge-to-edge dications define channels in which reside the anions. A range of C-H?N and C-H?O hydrogen-bonding interactions stabilizes the crystal packing.

Tetra-kis(triphenyl-arsane-?As)silver(I) trifluoro-acetate hemihydrate methanol hemisolvate.

Project description:The Ag(I) atom in the title hydrated solvated salt, [Ag(C18H15As)4](CF3CO2)·0.5CH3OH·0.5H2O, is coordinated by four As atoms from triphenyl-arsane ligands in a distorted tetra-hedral geometry. In the crystal, O-H?O hydrogen bonding occurs between carboxyl-ate groups of anions and lattice solvent mol-ecules. Of the four triphenyl-arsane ligands in the Ag complex cation, two each have an equally disordered phenyl ring while the trifluoro-acetate anion is disordered over two positions with respect to the lattice methanol and water mol-ecules which both show half-occupyncy. The crystal studied was a non-merohedral twin with a 13.6?(1)% contribution of the minor twin component.
