Structurally diverse Rh(I) and Mn(I) complexes derived from the new ambidentate indene ligand, (1-[iPr2P(S)]-2-[NMe2])C9H6.

A new indene-based ligand featuring pendant phosphine sulfide and amine donor fragments has been developed; Rh(I) coordinates to the neutral form of the ligand in a kappa2-[N,S] fashion, while the anionic form of the ligand binds Rh(I) and Mn(I) in kappa2-[C,S] and eta5 modes, respectively.
