چکیده
The title compound, trans-[PdBr(2)(C(6)H(10)N(2))(2)], was synthesized ionothermally in the ionic liquid solvent 1-ethyl-3-methyl-imidazolium bromide. In the crystal, the Pd(II) atoms are square-planarly coordinated to two Br atoms and two neutral (C(6)H(10)N(2)) ligands. The Pd(II) atom is located on an inversion centre.

The Pd(II) atom in the title compound, [PdBr(2){P(C(6)H(5))(3)}(2)]·CHCl(3), lies on a twofold rotation axis and is coordinated in a distorted square-planar geometry by two P atoms from two triphenyl-phosphine ligands and by two Br atoms in a trans arrangement. The chloro-form solvent mol-ecule is equally disordered about another twofold rotation axis.
