[1,4-Bis(di­phenyl­phosphan­yl)butane-κ²P,P′]di­bromido­palladium(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(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.
