【 摘 要 】

In the title complex, [RuCl2(C12H9BrN2)2] or [RuCl2(PM-BrA)2] (PM-BrA = 4-bromo-N-(2′-pyridyl­methyl­ene)aniline), the RuII cation is located on a centre of inversion and is surrounded by four N atoms of two PM-BrA ligands in the equatorial plane and by two Cl atoms in a trans axial arrangement, displaying a distorted octa­hedral coordination environment. Two C atoms in the benzene ring of the PM-BrA ligand are equally disordered over two sets of sites. The benzene and pyridine rings of the PM-BrA ligand are oriented at dihedral angles of 62.1 (10) and 73.7 (11)° under consideration of the two orientations of the disordered benzene ring. In the crystal, the complex mol­ecules are connected via C—H⋯Cl hydrogen-bonding inter­actions into a layered arrangement parallel (100). C—H⋯Br hydrogen bonding and weak aromatic π–π stacking inter­actions complete a three-dimensional supra­molecular network.
