Abstract:
The structure of the title compound, [Ti(C2H6N)2(C6H8N)Cl], displays a eta5-coordination mode for the pyrrolyl ring, confirmed by the values of the slip parameter [0.073 (9) A] and the fold angle [4.6 (6) degrees ]. This coordination is confirmed by NMR data, which point to the involvement of the complex in a fluxional process in solution above 285 K, passing through an intermediate involving simultaneously a metal-azaallyl and a metal-olefin bond.
