The complexes (Cy2PC3H6PCy2)Ni(η2-arene) (arene = toluene (3), naphthalene (4)) have been synthesized and studied in detail. Displacement reactions of the toluene ligand afford the complexes (Cy2PC3H6PCy2)Ni(η2-styrene) (5), (Cy2PC3H6PCy2)Ni(PhCN) (6), (Cy2PC3H6PCy2)Ni(CO)2 (7), (Cy2PC3H6PCy2)Ni(PPh3) (8), (Cy2PC3H6PCy2)Ni(PCy3) (9), (Cy2PC3H6PCy2)Ni}2(μ-H)2 (10), (Cy2PC3H6PCy2)Ni(η2-CO2) (11), and
