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

ABSTRACT: 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 ?-? inter-actions, both intra- and inter-molecular [shortest inter-centroid distance = 4.598?(5)?Å], are also noted in the three-dimensional architecture.
