Triple C−H bond activation in the reaction of [Cp(R 3 PN)Ti(Me) 2 ] with AlMe 3 affords Ti‐Al‐C aggregates. These species 1 and 2 exist in equilibrium with AlMe 3 , thus demonstrating a highly facile interconversion of carbide species with distorted tetrahedral and five‐coordinate, pseudo‐trigonal‐bipyramidal geometries, respectively.
