Crystal structure of trans-bis-{4-bromo-N-[(pyridin-2-yl)-methyl-idene]aniline-?(2) N,N'}di-chlorido-ruthenium(II).


ABSTRACT: In the title complex, [RuCl2(C12H9BrN2)2] or [RuCl2(PM-BrA)2] (PM-BrA = 4-bromo-N-(2'-pyridyl-methyl-ene)aniline), the Ru(II) 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 octa-hedral 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 mol-ecules are connected via C-H?Cl hydrogen-bonding inter-actions into a layered arrangement parallel (100). C-H?Br hydrogen bonding and weak aromatic ?-? stacking inter-actions complete a three-dimensional supra-molecular network.
