ABSTRACT: In the title compound, [RhCl(C(21)H(21)P)(2)(CO)], the coordination geometry around the Rh(I) atom is slightly distorted square-planar with the phosphane ligands in trans positions with respect to each other. The chloride and carbonyl ligands show positional disorder, and the Rh(I) atom lies on a center of inversion. The effective cone angle ?(E) for the title compound is 169.0?(3)°. There are no significant inter-molecular inter-actions.

Project description:The title compound, [RhCl(C(21)H(21)P)(2)(CO)]·C(3)H(6)O, was precipitated in trace yield from a reaction of RhCl(cod)(THP) with P(p-tol)(3) in a 1:1 acetone-d(6)/CD(3)OD solution under a hydrogen atmosphere [p-tol = p-tolyl, THP = tris-(hydroxy-meth-yl)phosphine, P(CH(2)OH)(3), and cod = 1,5-cyclo-octa-diene]. The complex displays a square-planar geometry around the Rh(I) atom. The complex mol-ecules and the acetone mol-ecules are linked into a chain along the a axis by inter-molecular C-H?Cl and C-H?O hydrogen bonds.

trans-Carbonyl-chloridobis[tris-(4-chloro-phen-yl)phosphane]rhodium(I) acetone monosolvate.

Project description:The title compound, trans-[RhCl(C(18)H(12)Cl(3)P)(2)(CO)]·C(3)H(6)O, contains an Rh(I) atom in a distorted square-planar coordination with a P-Rh-P angle of 175.27?(2)° and Rh-P bond lengths of 2.3127?(4) and 2.3219?(4)?Å. The rhodium complexes link each other through weak inter-molecular contacts between the acetone methyl groups and the carbonyl O atom. Inter-actions between the acetone solvent mol-ecule and the Cl-Rh unit results in a reduced P-Rh-Cl angle of 86.675?(15)°.

trans-Carbonyl-chloridobis[diphen-yl(4-vinyl-phen-yl)phosphane-?P]rhodium(I).

Project description:In the title compound, trans-[RhCl(C(20)H(17)P)(2)(CO)], the Rh(I) atom is situated on a center of symmetry, resulting in a statistical 1:1 disorder of the chloride [Rh-Cl = 2.383?(2)?Å] and carbonyl [Rh-C = 1.752?(7)?Å] ligands. The distorted trans square-planar environment is completed by two P atoms [Rh-P = 2.3251?(4)?Å] from two diphen-yl(4-vinyl-phen-yl)phosphane ligands. The vinyl group is disordered over two sets of sites in a 0.668?(10):0.332?(10) ratio. The crystal packing exhibits weak C-H?Cl and C-H?O hydrogen bonds and ?-? inter-actions between the phenyl rings of neighbouring mol-ecules, with a centroid-centroid distance of 3.682?(2)?Å.

trans-Carbonyl-chloridobis[tris-(4-meth-oxy-phen-yl)phosphane-?P]rhodium(I).

Project description:The title complex, [RhCl(C(21)H(21)O(3)P)(2)(CO)], is a rhodium analogue to Vaska's complex with para-meth-oxy substituents on the six phosphan-yl-aryl units. Two independent mol-ecules are present in the unit cell, with their metal atoms both located on an inversion centre. This causes the chloride and carbonyl ligands to exhibit a positional disorder in a 0.5:0.5 ratio. The two Rh(I) atoms exhibit a distorted square-planar geometry. There are a few weak intra-molecular C-H?X inter-actions (X = O, Cl). Inter-estingly, no significant inter-molecular inter-actions are found between the two independent mol-ecules.

Project description:In the title compound, trans-[RhCl{P(C(10)H(7))(3)}(2)(CO)]·3C(3)H(6)O, where P(C(10)H(7))(3) is trinaphthyl-phosphine, the Rh-P bond lengths are 2.3360?(10) and 2.3258?(10)?Å, while the Rh-Cl bond length is 2.3525?(11)?Å. The coordination around the Rh atom shows a slightly distorted square-planar arrangement.

trans-Carbonyl-chloridobis[dicyclo-hex-yl(4-isopropyl-phen-yl)phosphane]rhodium(I) acetone monosolvate.

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.

trans-Carbonyl-chloridobis(ethyl-diphenyl-phosphine-κP)rhodium(I).

Project description:The title compound, [RhCl(C(14)H(15)P)(2)(CO)], crystallizes with two almost identical mol-ecules in the asymmetric unit. The mol-ecules have the Rh(I) atom in a square-planar geometry. The crystal structure involves intermolecular C-H⋯O hydrogen bonds.

trans-Tetra-carbonyl-bis-(tri-phenyl-phosphane-κP)molybdenum(0).

Project description:The well known title compound, trans-[Mo(C18H15P)2(CO)4], has not been studied previously by X-ray crystallography, unlike its cis isomer. The complex possesses crystallographically imposed inversion symmetry, with the Mo atom residing on an inversion centre (1a Wyckoff position). The two tri-phenyl-phosphane groups are arranged in a staggered orientation. Each of the phenyl groups exhibits significantly different Mo-P-C-C torsion angles ranging from 2.6 (2) to 179.4 (1)°, most likely due to steric inter-actions based upon their positions relative to the carbonyl ligands.

<i>trans</i>-Carbonyl-chlorido-bis-(tri-ethyl-phosphane-κ<i>P</i>)platinum(II) tetra-fluorido-borate.

Project description:The chemical formulation of the title compound was established as trans-[PtCl{P(C2H5)3(CO)}BF4 by single-crystal X-ray analysis, in contrast to the five-coordinate tetra-fluoro-ethyl-ene complex that had been anti-cipated. The compound had been prepared by reaction of trans-PtHCl(P(C2H5)3)2 with C2F4 in the absence of air, and the presence of the carbonyl group was not suspected. The square-planar cations and BF4 - anions are linked by C-H⋯F and C-H⋯O inter-actions into thick wavy (010) sheets. The present crystal-structure refinement is based on the original intensity data recorded in 1967.
