(Acetyl-acetonato-?O,O')carbon-yl{dicyclo-hex-yl[4-(dimethyl-amino)-phen-yl]phosphane-?P}rhodium(I).

ABSTRACT: The title compound, [Rh(C(5)H(7)O(2))(C(20)H(32)NP)(CO)], features an acetyl-acetonate-chelated Rh(I) cation coordinated by one P [Rh-P = 2.2525?(7)?Å], one carbonyl C [Rh-C = 1.792?(3)?Å] and two O [Rh-O = 2.0582?(17) and 2.0912?(18)?Å] atoms in a slightly distorted square-planar geometry. Mol-ecules are packed in positions of least steric hindrance, with the phosphane ligands positioned above and below the Rh-acetyl-acetonate backbone.

Effective cone angles for the two P atoms are 165 and 161°, respectively. Both isopropyl groups and the acetone mol-ecule are disordered with occupancy values of 0.523 (5):0.477 (5), 0.554 (8):0.446 (8) and 0.735 (4):0.265 (4), respectively.

Project description:In the title compund, C(21)H(33)PSe, the Se=P bond is part of a distorted tetra-hedral environment on the P atom. Both cyclo-hexyl groups adopt chair conformations. A cone angle of 170° was calculated using an adaptation of the Tolman model. Inter-molecular C-H?Se and C-H?Cg contacts are observed (Cg is the centroid of the benzene ring).

Project description:The title compound, [PdCl(2)(C(21)H(33)P)(2)], forms a monomeric complex with a trans-square-planar coordination geometry about the Pd(II) atom which lies on an inversion centre. The Pd-P bond lengths are 2.3760 (13) Å, while the Pd-Cl bond lengths are 2.3172 (14) Å.

Project description:In the title complex, trans-[PtCl2{P(C6H11)2(4-Me2NC6H4)}2]·2CH2Cl2, the Pt(II) atom is located on an inversion centre, resulting in a trans-square-planar geometry. Important geometric parameters are the Pt-P and Pt-Cl bond lengths of 2.3258?(6) and 2.3106?(6)?Å, respectively, and the P-Pt-Cl angles of 89.64?(2) and 90.36?(2)°. The effective cone angle for the dicyclo-hex-yl[4-(dimethyl-amino)-phen-yl]phosphane unit was calculated to be 164°. The compound crystallizes with two dichloro-methane solvent mol-ecules; one of which is severely disordered and was treated using the SQUEEZE routine in PLATON [Spek (2009 ?). Acta Cryst.

Project description:The title compound, [Rh(C(5)H(7)O(2))(C(18)H(12)Cl(3)P)(CO)], contains the bidentate acetyl-acetonate ligand coordinated to the Rh(I) atom, forming a chelate ring [Rh-O = 2.0327?(15) and 2.0613?(14)?Å]. The Rh(I) atom is additionally coordinated by one P [Rh-P = 2.2281?(6)?Å] and one carbonyl C [Rh-C = 1.812?(2)?Å] atom, resulting in a slightly distorted square-planar geometry. The mol-ecules are packed to minimize steric hindrance with the phosphanes positioned above and below the slightly distorted square geometrical plane.

Project description:In the title compound, [Rh(C(5)H(7)O(2))(C(18)H(14)BrP)(CO)], the Rh(I) atom adopts a slightly distorted square-planar geometry involving two O atoms [Rh-O = 2.077?(2) and 2.033?(2)?Å] of the acetyl-acetonate ligand, one carbonyl C atom [Rh-C = 1.813?(2)?Å] and one P atom [Rh-P = 2.242?(5)?Å] of the PPh(2)(2-BrC(6)H(4)) phosphane ligand. Difference electron density maps indicate a disorder of the Br atom over two positions in an approximate 0.95:0.05 ratio. However, this disorder could not be resolved satisfactorily with the present data.

Project description:The title compound, [PdCl(2){P(C(6)H(11))(2)(C(6)H(5))}(2)], forms a monomeric complex with a trans-square-planar geometry.

One of the cyclo-hexyl rings is disordered with the phenyl ring in a 0.587?(9):413?(9) ratio. Five long-range C-H?Cl inter-actions were observed within the structure.
