The asymmetric unit of the title compound, C6H5Cl2N·2C11H11Cl2NO, is composed of one mol-ecule of an enamino-ketone [i.e. -(2,6-dichloro-phenyl-amino)-pent-3-en-2-one] and half a mol-ecule of 2,6-dichloro-aniline, the whole mol-ecule of the latter component being generated by twofold rotational symmetry. In this latter mol-ecule, there are two(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)
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)(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)

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)
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.

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, [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)
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)
