(2,2'-Bipyridine-²N,N')tetrabromidoplatinum(IV)

K. Ha

Abstract: In the title complex, [PtBr₄(C₁₀H₈N₂)], the Pt^IV ion has a slightly distorted octahedral coordination defined by two N atoms of the chelating 2,2'-bipyridine ligand and four bromide ions. As a result of the different trans effects of the N and Br atoms, the Pt-Br bonds trans to the N atom are slightly shorter than those to mutually trans Br atoms. In the crystal structure, the molecules are arranged in a V-shaped packing pattern along the b axis and stacked in columns along the a axis. In the columns, several intermolecular - interactions between the pyridine rings are present. The shortest ring centroid-centroid distance is 3.921 (6) Å, with a dihedral angle of 1.6 (5)° between the ring planes. The complexes are connected by C-HBr hydrogen bonds, forming chains along the b axis.
