[1,4-Bis(di-phenyl-phosphan-yl)butane-κ(2) P,P']di-bromido-palladium(II).

In the title complex, [PdBr2(C28H28P2)], the Pd(II) ion has a distorted cis-Br2P2 square-planar coordination geometry defined by two P atoms from the chelating 1,4-bis-(di-phenyl-phosphan-yl)butane ligand and two Br(-) anions. The four phenyl rings are inclined to the least-squares plane of the PdBr2P2 unit [maximum deviation = 0.1294 (7) Å], making dihedral angles of 66.3 (2), 87.2 (2), 68.8 (2) and 86.8 (2)°. The butyl-ene chain is in a gauche conformation, with a C-C-C-C torsion angle of 57.0 (8)°. Inter-molecular C-H⋯Br hydrogen bonds link the complex mol-ecules into supra-molecular layers in the ab plane. Weak π-π inter-actions, both intra- and inter-molecular [shortest inter-centroid distance = 4.598 (5) Å], are also noted in the three-dimensional architecture.
