Bis[μ-bis-(diphenyl-phosphan-yl)methane-κ(2)P:P']bis-[(isoquinoline-κN)silver(I)] bis-(trifluoro-methane-sulfonate)-isoquinoline (1/1).

ABSTRACT: The title complex, [Ag(2)(C(25)H(22)P(2))(2)(C(9)H(7)N)(2)](CF(3)SO(3))(2)·C(9)H(7)N, was prepared by the reaction of silver(I) trifluoro-methane-sulfonate with isoquinoline and bis-(diphenyl-phosphan-yl)methane (dppm). The dinuclear mol-ecule is located about a center of inversion and the Ag(I) atom is coordinated by two dppm P atoms and one isoquinoline N atom, forming an eight-membered metalla ring. In addition, in the asymmetric unit, there is a half-mol-ecule of isoquinoline located about a center of inversion. Since this mol-ecule does not possess this symmetry, for one position in the ring there is superposition of both a C atom of a C-H group and the isoquinoline N atom. In the structure, the Ag-P distances [2.4296 (9) and 2.4368 (9) Å] agree with the corresponding distances in related structures, while the Ag-N bond length [2.489 (3) Å] is slightly longer than that in related structures. On the other hand, the P-Ag-P angle [156.44 (3)°] is much larger than the corresponding angles in related structures. The trifluoro-methane-sulfonate anions do not coordinate to Ag(I) atoms. As is usually found for these anions, the -CF(3) group is disordered over two orientations [occupancies = 0.57 (12) and 0.43 (12)].

Bis[N,N-bis-(diphenyl-phosphan-yl)cyclo-penta-namine-?²P,P']platinum(II) bis-(trifluoro-methane-sulfonate).

Project description:The title compound, [Pt(C??H??NP?)?](CF?SO?)?, consists of a Pt(II) atom, situated on an inversion centre, coordinated by two diphosphinoamine bidentate ligands and charge-balanced by two trifluoro-methane-sulfonate anions. The Pt(II) atom has a distorted square-planar geometry defined by the four P atoms. The distortion is illustrated by the P-Pt-P bite angle of 70.31?(4)°. The geometry around the N atom deviates from a trigonal-planar geometry, evidenced by the P-N-P bite angle of 102.3?(2) °. The N atom is displaced by 0.114?(4)?Å from the C/P/P plane. In order to coordinate, the orientation of the phenyl rings alters from a C(s) conformation to a C(2v) conformation. The cyclo-pentane ring is slightly twisted: the puckering parameters are q(2) = 0.420?(5)?Å and ? = 26.5?(8) °. The trifluoro-methane-sulfonate anion displays a 0.511?(11):0.489?(11) positional disorder. Weak inter- and intra-molecular C-H?O hydrogen bonds influence the crystal packing.

Project description:In the title Ru(II) carboxyl-ate compound, [Ru(C2H3O2)(C26H24P2)2](CF3O3S)0.75Cl0.25, the distorted tris-bidentate octa-hedral stereochemistry about the Ru(II) atom in the complex cation comprises four P-atom donors from two 1,2-bis-(diphenyl-phosphan-yl)ethane ligands [Ru-P = 2.2881 (13)-2.3791 (13) Å] and two O-atom donors from the acetate ligand [Ru-O = 2.191 (3) and 2.202 (3) Å]. The disordered counter-anions are located on the same site in the structure in a 3:1 ratio, the expanded formula comprising four complex cations, three trifluoro-methane-sulfonate anions and one chloride anion, with two such formula units in the unit cell.

trans-Diaqua-bis(2,2'-bipyridine-κN,N')ruthenium(II) bis-(trifluoro-methane-sulfonate).

Project description:The title compound, trans-[Ru(bpy)(2)(H(2)O)(2)](CF(3)SO(3))(2) (bpy = 2,2'-bipyridine, C(10)H(8)N(2)), crystallized from the decomposition of an aged aqueous solution of a dimeric complex of cis-Ru(bpy)(2) in 0.1 M triflic acid. The Ru(II) ion is located on a crystallographic inversion center and exhibits a distorted octa-hedral coordination with equivalent ligands trans to each other. The Ru-O distance is 2.1053 (16) Å and the Ru-N distances are 2.0727 (17) and 2.0739 (17) Å. The bpy ligands are bent, due to inter-ligand steric inter-actions between H atoms of opposite pyridyl units across the Ru center. The crystal structure exhibits an extensive hydrogen-bonding network involving the water ligands and the trifluoromethane-sulfonate counter-ions within two-dimensional layers, although no close hydrogen-bond inter-actions exist between different layers.

Project description:In the title compound, [Ag(2)(C(12)H(12)N(2))(C(21)H(15)N(3))(2)](CF(3)SO(3))(2), the Ag(I) atom is coordinated by three N atoms of one 4'-phenyl-2,2':6',2''-terpyridine (phtpy) ligand and one pyridyl N atom of the 1,2-bis-(4-pyrid-yl)ethane (bpe) ligand, displaying a distorted square-planar geometry. Two Ag(I) atoms are bridged by one trans-bpe ligand, generating a dinuclear cation. The dinuclear cation is located on a centre of inversion, which is in the middle of the ethyl-ene fragment of the bpe ligand. In the crystal, the pyridyl rings of neighboring dinuclear units are stacked by π-π inter-actions with centroid-centroid distances of 3.667 (2) and 3.835 (2) Å. The F and O atoms of the CF(3)SO(3) (-) anions are involved in inter-molecular C-H⋯F and C-H⋯O hydrogen-bonding inter-actions, respectively, with -CH groups from the phtpy ligands.

Project description:The asymmetric unit of the title salt, [Ag(C(14)H(14)N(4)O(2))(1.5)](CF(3)SO(3)), comprises a Ag(+) cation, three half-mol-ecules of N,N'-bis-(2-pyridyl-meth-yl)oxalamide (each of which is dis-posed about a centre of inversion) and a trifluoro-methane-sulfonate anion. Distinct coordination modes are found for the bridging ligands, i.e., a μ(2),κ(2)-bridging mode involving pyridine N atoms for one ligand, and a μ(2),κ(4)-bridging mode, employing both pyridine N and amide O atoms for the remaining ligands. The Ag(+) cations, which are in a distorted square-pyramidal coordination, and the ligands combine to form a two-dimensional array parallel to (101); these arrays are connected into a three-dimensional structure by trifluoro-methane-sulfonate anions via N-H⋯O, C-H⋯O, and C-F⋯O inter-actions.

The axial Ru-P bonds are longer than the equatorial Ru-P bonds and there is an acute P-Ru-P angle.

The PdC(3)P and PdC(2)P(2) five-membered metallacycles adopt envelope and twist conformations, respectively. In the crystal, inter-molecular C-H?O hydrogen bonds link cations and anions into a three-dimensional network. The dichloro-methane solvent mol-ecule is disordered over three orientations with a site-occupancy ratio of 0.5/0.3/0.2.

Two dppm ligands, two dpp ligands and two trifluoro-acetate anions bridge four metal atoms, forming a centrosymmetric tetra-nuclear complex. Intra-molecular C-H?O hydrogen bonds and a weak ?-? inter-action [centroid-centroid distance = 3.9804?(13)?Å] are also observed.

(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.
