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

ABSTRACT: 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.

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.
