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

ABSTRACT: 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.

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.

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

Project description: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) 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.

Tetra-kis(μ-phenoxy-acetato-κO:O')bis-[(1,10-phenanthroline-κN,N')manganese(II)] methanol hemisolvate.

Project description:The title complex, [Mn(2)(C(8)H(7)O(3))(4)(C(12)H(8)N(2))(2)]·0.5CH(3)OH, is a carboxyl-ate-bridged dinuclear Mn(II) complex with four phenoxy-acetate ions and two 1,10-phenanthroline mol-ecules as ligands. Each of the four phenoxy-acetate anions bridges the pair of Mn atoms. The asymmetric unit is completed by a half-occupancy methanol solvent mol-ecule. Face-to-face π-π stacking inter-actions between the aromatic rings of 1,10-phenanthroline molecules belonging to adjacent Mn(2) complexes, with an inter-planar separation of circa 3.4 Å, and weak C-H⋯O hydrogen bonds connect the dinuclear units into a three-dimensional supra-molecular framework.

Crystal structure of an unknown tetra-hydro-furan solvate of tetra-kis-(? 3-cyanato-?(3) N:N:N)tetra-kis-[(triphenyl-phosphane-?P)-silver(I)].

Project description:In the title compound, [{[(C6H5)3P]Ag}4{NCO}4], a distorted Ag4N4-heterocubane core is set up by four Ag(I) ions being coordinated by the N atoms of the cyanato anions in a ? 3-bridging mode. In addition, a tri-phenyl-phosphine ligand is datively bonded to each of the Ag(I) ions. Intra-molecular Ag?Ag distances as short as 3.133?(9)?Å suggest the presence of argentophilic (d (10)?d (10)) inter-actions. Five moderate-to-weak C-H?O hydrogen-bonding inter-actions are observed in the crystal structure, spanning a three-dimensional network. A region of electron density was treated with the SQUEEZE procedure in PLATON [Spek (2015). Acta Cryst. C71, 9-18] following unsuccessful attempts to model it as being part of disordered tetra-hydro-furan solvent mol-ecules. The given chemical formula and other crystal data do not take into account these solvent mol-ecules.

Pyridinium tetra-kis-(1,1,1-trifluoro-pentane-2,4-dionato)dysprosate.

Project description:In the anion of the title compound, (C(5)H(6)N)[Dy(C(5)H(4)F(3)O(2))(4)], the central metal ion, Dy(3+), is coordinated by four bidentate 1,1,1-trifluoro-pentane-2,4-dionate (TAA) ligands, forming an approximate square-anti-prismatic configuration. The pyridin-ium cation is connected to the complex ion by an N-H?O hydrogen bond and electrostatic inter-actions in the crystal. There are two kinds of disorder in the structure, one involving rotational disorder of a CF(3) group [occupancy ratio 0.560?(15):0.440?(15)] and the other involving an exchange between a CF(3) group and CH(3) group within a given bidentate ligand (occupancy ratio 0.64:0.36).

(Methanol-?O)(perchlorato-?O)bis-(triphenyl-phosphine-?P)silver(I).

Project description:In the title complex, [Ag(ClO(4))(CH(3)OH)(C(18)H(15)P)(2)], the angles around the central Ag(+) ion indicate that it is in a distorted tetrahedral coordination. The coordination sphere of silver is formed by two P atoms of two triphenyl-phosphine ligands, one O atom of a perchlorate anion and one O atom of a methanol mol-ecule. The crystal structure is stablized by a bifurcated inter-molecular O-H?O hydrogen bond, involving the O-H donor from methanol and two acceptor O atoms from the perchlorate anion, so forming a zigzag chain propagating in [010].
