complex (2) show a distorted octahedral geometry around the ruthenium centre. The mononuclear complex adopts a typical three legged piano-stool geometry (a description commonly used for half–sandwich compounds) with the metal centre coordinated by two chlorides and a TSC ligand. The coordination geometry around RuII atom is distorted octahedron with three sites occupied by the p-cymene ligand (with an ƞ6
