“…The most intense ESMS ions were MeO À adducts derived from [Ru 3 (CO) 11 (CNPh)] and [Ru 3 (CO) 10 (CNPh) 2 ]. An equivalent higher-nuclearity series of the type [Ru 4 (CO) 14 À n (CNPh) n ] (n ¼ 2-4) was also observed.…”

“…The formal electron count averages 18 for each metal atom; 19 for Ru(1) and Ru(4) and 17 for Ru (2) and Ru (3) atoms. This is calculated assuming the bridging isonitrile ligands each donate one electron to each metal from the carbon atom and two electrons to the unique Ru(4) from the nitrogen atoms.…”

“…This leads to the bridged C 2v structure for the former but a nonbridged D 3h structure for the latter. [Fe 3 (CO) 12 ] has also been the archetypal compound for the sometimes heated arguments concerning the mechanisms for COligand fluxionality [2].…”

“…For [Ru 3 (CO) 10 (CNBu t ) 2 ] the disorder is 50:50, with the isonitrile ligands attached to different Ru atoms [9].…”

“…This is most readily understood in terms of Johnson's model -the almost constant ligand polyhedron determines the crystal packing and hence space group, with the varying metal cores occupying the central hole according to their sizes and ease of rotation within the cage [1]. The work on the structures and fluxionality of all three [M 3 (CO) 12 ] members of the iron triad has been reviewed [2].…”

The reactions of [Fe 3 (CO) 12 ] or [Ru 3 (CO) 12 ] with RNC (R ¼ Ph, C 6 H 4 OMe-p or CH 2 SO 2 C 6 H 4 Me-p) have been investigated using electrospray mass spectrometry. Species arising from substitution of up to six ligands were detected for [Fe 3 (CO) 12 ], but the higher-substituted compounds were too unstable to be isolated. The crystal structure of [Fe 3 (CO) 10 (CNPh) 2 ] was determined at 150 and 298 K to show that both isonitrile ligands were trans to each other on the same Fe atom. For [Ru 3 (CO) 12 ] substitution of up to three COs was found, together with the formation of higher-nuclearity clusters. [Ru 4 (CO) 11 (CNPh) 3 ] was structurally characterised and has a spiked-triangular Ru 4 core with two of the CNPh ligands coordinated in an unusual l 3 -g 2 mode.
