In the title complex, [PdBr2(C28H28P2)], the PdII ion has a distorted cis-Br2P2 square-planar coordination geometry defined by two P atoms from the chelating 1,4-bis(diphenylphosphanyl)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 butylene chain is in a gauche conformation, with a C—C—C—C torsion angle of 57.0 (8)°. Intermolecular C—H...Br hydrogen bonds link the complex molecules into supramolecular layers in the ab plane. Weak π–π interactions, both intra- and intermolecular [shortest inter-centroid distance = 4.598 (5) Å], are also noted in the three-dimensional architecture.
