Metal in motion : The reaction of [Ru 5 (CO) 15 ( μ 5 ‐C)] with [Pt(P t Bu 3 ) 2 ] yields [Ru 5 Pt(P t Bu 3 )(CO) 15 (C)]. The product exists as two isomers, an open and a closed form, which interconvert rapidly on the NMR timescale by a process that resembles the diffusion of metal adatoms across a metal surface (see scheme; at 20°C the rate=24 000 s −1 ).
