The title compound, [Ag(C(7)H(5)O(2))(C(18)H(15)P)(2)]·CH(2)Cl(2), crystallizes with a distorted tetra-hedral geometry about the Ag(I) atom, defined by two O atoms from one tropolonate ligand and two P atoms from two triphenyl-phosphine ligands. It is an example of a new type of tropolone derivative that has not been characterized via solid-state methods.
In the title compound, [Rh(C(13)H(16)NO)(C(18)H(15)P)(CO)]·0.5C(3)H(6)O, the Rh atom exhibits a square-planar coordination geometry, being coordinated by the N and O atoms of the bidentate β-diketonato ligand, a P atom from the triphenyl-phosphine unit and a C atom from the carbonyl group. The asymmetric unit also contains a disordered half-mol-ecule, lying(More)
In the title compound, [Zr(C(5)H(4)F(3)O(2))(4)]·C(7)H(8), the Zr atom is in a square-anti-prismatic coordination geometry that comprises four O,O'-bidentate trifluoro-acetyl-acetonate ligands. The O-Zr-O bite angles of the acetonate ligands range from 75.27 (5) to 75.41 (5)°. The Zr atom is located on a twofold rotation axis.

The title compound, [Cu(NO(3))(C(18)H(15)P)(3)]·CH(3)OH, is a methanol solvate derivative of nitratotris(triphenyl-phos-phine)copper(I). The complex crystallizes with three triphenyl-phosphine ligands coordinated to the copper centre, with an O-H⋯O hydrogen bond observed between the nitrate ligand and the methanol solvent mol-ecule. The coordination around(More)
In the title compound, [PdBr(2)(C(19)H(17)P)(2)], the Pd(II) ion resides on a centre of symmetry and is coordinated by two Br anions [Pd-Br = 2.4266 (2) Å] and two P-donor ligands [Pd-P = 2.3462 (5) Å] in a slightly distorted square-planar geometry [P-Pd-Br = 93.528 (12)°]. Weak inter-molecular C-H⋯Br hydrogen bonds link mol-ecules into chains extended in(More)

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)(More)
In the title compound, [Rh(C(13)H(16)NO)(C(18)H(15)P)(CO)], the coordination geometry of the Rh(I) atom is square-planar, formed by the coordinating N and O atoms of the bidentate enaminoketonate ligand, one C atom from the carbonyl group and a P atom from triphenyl-phosphine. The complex displays a 0.591 (3):0.409 (3) ratio disorder of the phenyl unit of(More)
In the title compound, [Cu(C(6)H(5)O(3))(C(18)H(15)P)(2)]·C(18)H(15)P·CH(3)OH, the pyran-4-one ring is appromimately planar (r.m.s deviation = 0.0138 Å), with the Cu(I) atom 0.451 (5) Å out of the plane. The Cu(I) atom has a distorted tetra-hedral coordination. The O-Cu-O angle is 80.07 (8)° and the P-Cu-P angle is 123.49 (3)°. The crystal packing is(More)
In the title compound, [Rh(C(13)H(16)NO)(CO)(2)], a square-planar coordination geometry is observed around the Rh(I) atom, formed by the N and O atoms of the bidentate ligand and two C atoms from two carbonyl ligands. The Rh(I) atom is displaced from the plane through these surrounding atoms by 0.0085 (2) Å. The dihedral angle between the benzene ring and(More)
