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

ABSTRACT: 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. (2012 ▶). Acta Cryst. E68, m404].

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.

Project description:There are two independent mol-ecules with similar configurations in the asymmetric unit of the title complex, [Pd(C(4)H(3)N(2))I(C(18)H(15)P)(2)]. In each mol-ecule, the geometry around the Pd atom is distorted square-planar, with the Pd atom displaced by 0.0549 (12) and 0.0734 (13) Å from the least-squares plane of the I-P-P-C atoms. The PPh(3) ligands are in trans positions, with P-Pd-P angles of 173.12 (4) and 170.29 (4)°, while the pyrazinyl ligands and I atoms, also trans to each other, form C-Pd-I angles of 179.38 (12) and 178.44 (12)°. In the crystal, C-H⋯π inter-actions occur, resulting in a three-dimensional supramolecular architecture.
