Several new Ru(III) DMSO compounds including [PPh4]trans-[Ru(DMSO)2Cl4], [PPh4]trans-[Ru(DMSO)(pyrazine)Cl4] (2), [PPh4]trans-[Ru(DMSO)(4,4′-bipyridine)Cl4] and [PPh4]trans-[Ru(DMSO)(pyrimidine)Cl4] were reported and characterized. The crystal structure of 2 and its Na+ analogue were determined by X-ray diffraction methods. The PPh4+ complex 2 is a discrete ionic compound, while the compound [Na]trans-[Ru(DMSO)(pyrazine)Cl4] · DMSO (3) crystallized with a molecule of DMSO. The environment around the Na atom is a distorted octahedron with short contacts with three chloro ligands, two O atoms from the bonded and unbonded DMSO molecules, and the unbonded N atom of the pyrazine ligand. The Na atoms form bridges between the complexed anions in 3 resulting in the formation of infinite chains or ribbons parallel to the b axis. The chains are held together by van der Waals interactions.
