Abstract:
In the dimeric title compound, [Pd2Cl4{P(C8H9)3}2]·CH2Cl2, the metal complex molecule is situated about an inversion centre and is accompanied by a dichloro-methane solvent mol-ecule situated on a twofold rotation axis. The Pd(II) atom has a slightly distorted square-planar coordination sphere. The effective cone angle for the tris-(3,5-dimethyl-phen-yl)phos-phane ligand was calculated to be 169°. In the crystal, the metal complex and solvent mol-ecules are linked via C-H⋯Cl inter-actions, generating chains along [10-2]. There are also C-H⋯π and weak π-π inter-actions present [centroid-centroid distance = 3.990 (2) Å, plane-plane distance = 3.6352 (15) Å and ring slippage = 1.644 Å], forming of a three-dimensional structure.
