(Received 6 September 2012; accepted 27 September 2012; online 6 October 2012)

The title compound, [PdCl2(C21H33P)2], forms a monomeric complex with a trans-square-planar coordination geometry about the PdII 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[dicyclo­hex­yl(phen­yl)phosphane-κP]palladium(II), [PdCl2{P(C6H11)2(C6H5)}2] [Burgoyne et al. (2012[Burgoyne, A. R., Meijboom, R. & Ogutu, H. (2012). Acta Cryst. E68, m404.]). Acta Cryst. E68, m404].

Comment top

Complexes involving palladium metal centres are amongst some of the most popular catalytic precursors in organic synthesis due to their catalytic abilities. They are used in carbon-carbon bond formation reactions like the Heck, Stille and Suzuki reactions (Bedford et al., 2004).[PdCl2(L)2] (L = tertiary phosphine, arsine or stibine) complexes can conveniently be prepared by the substitution of 1,5-cyclooctadiene (COD) from [PdCl2(COD)]. The title compound, trans-[PdCl2(C21H33P)2], crystallizes with the Pd atom on a center of symmetry and each pair of equivalent ligands in a mutually trans orientation.The geometry is,therefore, slightly distorted square planar and the Pd atom is not elevated out of the coordinating atom plane. All angles in the coordination polyhedron are close to the ideal value of 90°, with Cl2—Pd1—P1 = 88.39 (6)° and Cl2—Pd1—P1 = 91.61 (6)°. As required by the crystallographic symmetry, the Cl2—Pd1—Cl2 and P1—Pd1—P1 angles are 180°. The symmetry code used to define atoms through the inversion point is: 1 - x, -y, 1 - z.

The title compound compares well with other closely related PdII complexes from the literature containing two chloro and two tertiary phosphine ligands in a trans geometry (Muller & Meijboom, 2010a, b). The title compound, having a Pd1—Cl2 bond length of 2.3172 (14) Å and a Pd—P bond length of 2.3760 (13) Å, fits well into the typical range for complexes of this kind. Notably the title compound did not crystallize as a solvated complex; these type of PdII complexes have a tendency to crystallize as solvates (Ogutu & Meijboom, 2011).

Notably, the title compound is quintessentially isostructural with: [PdCl2{P(C6H11)3}2] (Grushin et al., 1994); [PdBr2{P(C6H11)3}2] (Clarke et al., 2003); and [PdCl2{P(C6H11)2(C7H7)}2] (Vuoti et al., 2008) ((C6H11) = cyclohexyl, (C7H7) = o-tolyl). The Pd–P and Pd–X (X = Br and Cl) bond lengths were compared and it was observed that they were all within the same range of 2.3–2.4 Å. The angles between the bonds around the Pd atom were all observed to be approximately right angles.

Experimental top

Dicyclohexyl-(2,4,6 trimethyl phenyl)phosphine (0.11 g, 0.35 mmol) was dissolved in acetone (5cm3). A solution of [Pd(COD)Cl2] (0.05 g,0.17 mmol) in acetone (5 cm3) was added to the phosphine solution. The mixture was stirred for 5 minutes, after which the solution was left to crystallize. Yellow crystals of the title compound suitable for X-ray diffraction studies were obtained. 1H NMR (CDCl3, 400 MHz,p.p.m.): 6.9–6.8(m, 4H), 2.3 (m, 18H),1.5–1.4 (m, 16H),1.5 (m, 8H),1.6 (m, 16H),1.3 (m, 16H), 1.4 (m, 4H).31P NMR (CDCl3, 162.0 MHz, p.p.m.): 80.82. FTIR (cm-1):2920, 2850, 1713, 1678, 1597, 1553, 1442, 1337, 1074, 998, 883, 846, 728,

Refinement top

The aromatic, methine, and methyl H atoms were placed in geometrically idealized positions (C—H = 0.95–0.98) and constrained to ride on their parent atoms, with Uiso(H) = 1.2Ueq(C) for aromatic and methine H atoms, and Uiso(H) = 1.5Ueq(C) for methyl H atoms respectively. Methyl torsion angles were refined from electron density.

Geometry. All esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds involving l.s. planes.

Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > 2sigma(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger.
