Clusters containing metal–metal bonds linking high- and low-valent metal centres: synthesis and structure of Ru3(CO)12{Mo(NAr)2}
Abstract
Room temperature reaction of K2[Ru3(CO)11] with the molybdenum(VI) bis(imido) complexes Mo(NAr)2Cl2(dme) (Ar = C6H3X2-2,6; X = Me, Pri, Cl; dme = 1,2-dimethoxyethane) affords new high-low valent clusters Ru3(CO)12{Mo(NAr)2} which adopt a butterfly arrangement of metal centres with [Ru3(CO)12]2 acting as a ligand at a molybdenum(VI) centre.
