S. Ali et al., Clusters containing metal-metal bonds linking high- and low-valent metal centres: synthesis and structure of Ru-3(CO)(12){Mo(NAr)(2)}, CHEM COMMUN, (2), 2000, pp. 123-124
Room temperature reaction of K-2[Ru-3(CO)(11)] with the molybdenum(VI) bis(
imido) complexes Mo(NAr)(2)Cl-2(dme) (Ar = C6H3X2-2,6; X = Me, Pr-i, Cl; dm
e = 1,2-dimethoxyethane) affords new high-low valent clusters Ru-3(CO)(12){
Mo(NAr)(2)} which adopt a butterfly arrangement of metal centres with [Ru-3
(CO)(12)](2-) acting as a ligand at a molybdenum(VI) centre.
