Complexes of the type [Ru(η5-C7H11)L3]+ and [Ru(η5-C7H11)L2X] exhibit dynamic behaviour in solution due to rotation of the DMP ligand with respect to the RuL3 or RuL2X groups, and activation energies for twelve of the complexes have been evaluated. Exchange of free and coordinated acetonitrile in solutions of [Ru(η5-C7H11)(NCCH3)3]BF4 is non-stereospecific and associative in character.",
