Project description: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.

Project description:The title rhodium Vaska-type complex, trans-[RhCl{P(C(6)H(11))(2)(C(6)H(4)-4-C(3)H(7))(2)}(2)(CO)], crystallizes with an accompanying acetone solvent mol-ecule. The metal atom shows a distorted square-planar coordination environment with selected important geometrical parameters of Rh-P = 2.3237 (6) and 2.3253 (6) Å, Rh-Cl = 2.3724 (6) Å, Rh-C = 1.802 (2) Å, P-Rh-P = 173.42 (2)° and Cl-Rh-C = 179.13 (7)°. 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. The crystal packing is stabilized by weak C-H⋯O and C-H⋯Cl contacts.

Dicyclo-hex-yl(4-isopropyl-phen-yl)phosphane selenide.

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).

trans-Dichloridobis[dicyclo-hex-yl(2,4,6-trimethyl-phen-yl)phosphane-κP]palladium(II).

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. The observed structure was found to be closely related to that of trans-dichloridobis[dicyclo-hex-yl(phen-yl)phosphane-κP]palladium(II), [PdCl(2){P(C(6)H(11))(2)(C(6)H(5))}(2)] [Burgoyne et al.

trans-Dichloridobis[dicyclo-hex-yl(4-isopropyl-phen-yl)phosphane-?P]platinum(II) acetone monosolvate.

Project description:The title compound, [PtCl(2)(C(21)H(33)P)(2)]·C(3)H(6)O, crystallizes with an accompanying acetone solvent mol-ecule. The metal atom shows a distorted square-planar coordination environment, with a P-Pt-P angle of 172.41?(3)° as the most prominent feature. Both isopropyl fragments were treated as disordered over two conformations with occupancy ratios of 0.55?(2):0.45?(2) and 0.58?(2):0.42?(2). The solvent mol-ecule was also disordered over two orientations in a 1:1 ratio. The crystal studied was a non-merohedral twin with a twin component of 32.4%.

(Acetyl-acetonato-?(2)O,O')carbon-yl[tris-(4-chloro-phen-yl)phosphane-?P]rhodium(I).

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.

(Acetyl-acetonato-?(2)O,O')[(2-bromo-phen-yl)diphenyl-phosphane-?P]carbonyl-rhodium(I).

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.

trans-Dichloridobis[dicyclo-hex-yl(phen-yl)phosphane-?P]palladium(II).

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. The Pd-P bond lengths are 2.3343?(5)?Å, as the Pd atom lies on an inversion centre, while the Pd-Cl bond lengths are 2.3017?(4)?Å.

Dalton Trans. pp. 4393-4394] and [PdCl(2)P(C(6)H(11))(2)(C(7)H(7))}(2)] [Vuoti et al. (2008 ?). Eur. J. Inorg. Chem. pp. 397-407] (C(6)H(11) is cyclo-hexyl and C(7)H(7) is o-tol-yl). 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.

N-(2,6-Diisopropyl-phen-yl)formamide.

Project description:The title compound, C(13)H(19)NO, exhibits a non-planar structure in which the 2,6-diisopropyl-phenyl ring is tilted at a dihedral angle of 77.4?(1)° with respect to the formamide group. This is the largest dihedral angle known among structurally characterized formamides. The mol-ecules are linked via N-H?O hydrogen bonds, forming infinite chains which run along the b-axis directions.
