STRUCTURAL AND NMR STUDIES OF INDENYL HAPTICITY AND ROTATIONAL BARRIERS INTHE COMPLEXES (ETA -1-R-INDENYL)NI(PPH3)(X) (R = H, ME; X = CL, ME)

The relative trans influences of Cl and Me in the complexes (1-Me-indenyl)Ni(PPh3)Cl and (1-Me-indenyl)Ni(PPh3)Me lead to different solid state hapticities for the 1-Me-indenyl ligands. Comparing t...
