LoginovAbstractBis(indenyl)-rhodium and -iridium complexes [(η5-indenyl)M(η5-C9H2R5)]PF6 (2a: M = Rh, R = H; 2b: M = Ir, R = H; 3: M = Rh, R = Me) were synthesized by reactions of iodides [(η5-indenyl)MI2]n (1a,b) with indenes in the presence of AgPF6. The structures of 2aSbF6 and 2bPF6 were determined by X-ray diffraction. They have fully eclipsed geometry, in which the bridgehead carbon atoms of the indenyl ligands are arranged close to each other. Experimental and DFT calculation data showed that the strength of the M−indenyl bond in the bis(indenyl) compounds decreases in the following row: Ir > Co > Rh.Graphical abstract
