Bis[tris-(4-fluoro-phen-yl)phosphine-κP](tropolonato-κO,O')copper(I).

ABSTRACT: The title compound, [Cu(C(7)H(5)O(2))(C(18)H(12)F(3)P)(2)], a copper(I) tris-(4-fluoro-phen-yl)phosphine tropolonate derivative, is the first tropolonate complex with fluorinated aryl-phosphine ligands. The Cu(I) atom has a distorted tetra-hedral coordination; the most important geometrical parameters of the mol-ecule are: Cu-P = 2.2377 (10) and 2.2335 (15) Å, Cu-O = 2.084 (2) and 2.082 (2) Å, O-Cu-O = 77.72 (10)°, P-Cu-P = 128.82 (4)° and O-C-C-O = -2.1 (5)°.

(Nitrato-κO)tris-[tris-(4-fluoro-phen-yl)phosphane-κP]copper(I).

Project description:In the title complex, [Cu(NO(3))(C(18)H(12)F(3)P)(3)], the ligating atoms define a distorted tetrahedon with the three tris-(4-fluoro-phen-yl)phosphane ligands in the basal positions and the nitrate ligand in the axial position. The intra-molecular π-π inter-action [centroid-centroid distance = 3.6113 (11) Å] between two of the 4-fluoro-phenyl groups is complemented by both C-H⋯F and C-H⋯O inter-actions with distances in the range 2.51-2.60 Å, resulting in a tight head-to-tail packing.

Project description:In the title compound, [Cr(C(18)H(12)F(3)P)(2)(CO)(4)], the Cr atom is octa-hedrally coordinated by four carbonyl ligands and the two tertiary phosphanes that are trans to each other.

In the crystal, C-H⋯O and C-H⋯F inter-molecular inter-actions form an infinite three-dimensional network.

Chlorido[tris-(3-fluoro-phen-yl)phosphine]gold(I).

Project description:In the title gold complex, [AuCl(C(18)H(12)F(3)P)], the P-Au-Cl unit is nearly linear, with an angle of 178.13 (5)°. The three phosphine-substituted benzene rings make dihedral angles of 77.7 (3), 84.4 (3) and 77.4 (3)° with each other. Two of the three F atoms are disordered over two positions, with refined site occupancies of 0.591 (11):0.409 (11) and 0.730 (12):0.270 (12). In the crystal structure, mol-ecules are linked into a three-dimensional network by inter-molecular C-H⋯Cl and C-H⋯F hydrogen bonds.

Tris[3,5-bis-(trifluoro-meth-yl)phen-yl]phosphine oxide.

Project description:In the title compound, C(24)H(9)F(18)OP, an intra-molecular C-H⋯O short contact generates a five-membered ring, producing an S(5) ring motif. The dihedral angles between the benzene rings are 57.68 (10), 77.80 (11) and 79.48 (10)°. Each of the six trifluoro-methyl substituents shows rotational disorder over two positions with refined site-occupany ratios of 0.64 (3)/0.36 (3), 0.649 (14)/0.351 (14), 0.52 (2)/0.48 (2), 0.545 (16)/0.455 (16), 0.774 (9)/0.226 (9) and 0.63 (5)/0.37 (5). The crystal structure is stabilized by inter-molecular C-H⋯O and C-H⋯F inter-actions.

(Triphenyl-phosphine-κP)[1,1,1-tris-(diphenyl-phosphinometh-yl)ethane-κP,P',P'']copper(I) tetra-fluoridoborate.

Project description:In the title mononuclear Cu(I) complex, [Cu(C(18)H(15)P)(C(41)H(39)P(3))]BF(4), the cation has a basic rigid core structure reminiscent of the framework of diamond. The metal atom is coordinated by four P atoms in a distorted tetra-hedral geometry, the distortion arising from the steric hindrance of the phenyl groups. The anion is disordered over two positions, with an occupancy ratio of 0.524 (17):0.476 (17). The cations and anions are closely packed in the crystal and are in h.c.p. arrangements.

Chloridotris[tris-(4-fluoro-phen-yl)phosphine]rhodium(I) methanol solvate.

Project description:In the title compound, [RhCl{P(p-FC(6)H(4))(3)}(3)]·CH(3)OH, the Rh atom adopts a distorted square-planar geometry. Rh, Cl and one P atom lie on a mirror plane, as does the solvent molecule. There are two inter-molecular hydrogen bonds, one between the methanol O atom and an aryl H atom (2.51 Å), and one between the Cl atom and the hydr-oxy H atom of methanol [2.34 (3) Å]. The complex precipitates in trace amounts from a reaction between RhCl(cod)(thp) [cod is 1,5-cyclo-octa-diene and thp is tris-(hydroxy-meth-yl)phos-phine] and P(p-FC(6)H(4))(3) under argon in CD(3)OD. Two C(6)H(4)-F units are disordered over two positions; for one the site occupancy factors are ca. 0.53 and 0.47, for the other the values are ca. 0.64 and 0.36. The methyl H atoms of the solvent molecule are disordered across the mirror plane.
