The dinuclear cyclometalated complexes act as building blocks for the formation of tetranuclear species with the olefinic pyridyl ligands providing a stable coordination geometry and structural stability for these coordination compounds. The reaction of the racemic mixture of the homochiral dimers with configuration R, R)- and (S, S)- at the metal in the presence of bridging ligands... [Pg.120]
