The title compound, trans-[Pd2Cl4(PCy3)2]·C6H6, where PCy3 is tricyclohexylphosphine (C18H33P), cocrystallizes with one benzene molecule in the centrosymmetric space group P21/c and both molecules lie on inversion centers. Each Pd atom adopts a distorted square-planar geometry [angles vary from 84.23 (3) to 95.82 (3)°], and is bonded to a terminal chloride, a phosphine and two bridging chlorides. Bond lengths are typical of related species.

The Pd atom in the title complex, [PdCl2(C7H9N)2] or trans-[PdCl2(NH2CH2Ph)2], lies on a twofold axis. It has a distorted square-planar coordination environment formed by two benzylamine and two Cl- ligands. The symmetry-unique cis angles at the Pd atom are 86.25 (11) and 93.75 (11)°.

The title complex, trans-[PdCl2(PPh3)]2, in the crystal structure of its benzene disolvate, [Pd2Cl4(C18H15P)2]·2C6H6,occupies a special position in the inversion centre. The Pd atom has a distorted square-planar coordination environment formed by a triphenylphosphine [Pd—P 2.2278 (6) Å], a terminal chloride [Pd–Cl 2.2722 (7) Å], and two bridging chloride ligands. The Pd—μ-Cl bond in the trans-position to the phosphine ligand [2.4128 (6) Å] is considerably longer than the Pd—μ-Cl bond in the trans-position to the terminal chloride [2.3228 (6) Å].
