Depending on the steric demand of the phosphorus bound substituents, the action of the secondary phosphine sulphides R2P(H)S (1a–h) (R = Me (a), Et (b), iPr (c), tBu (d), Ph (e), Xyl (f), Mes (g), Cy (h)) on nickelocene results in the formation of either the dimeric complexes [(η5-C5H5)Ni (μ-SPR2)]2 (2a–c,e,h) or the monomeric thiophosphinito complexes (η5-C5H5)Ni(η2-SPR2) (3d,f,g).
