Abstract

2010302010116 ; 化學系 ; An X-ray analysis of (C(5)Me(5))MoRu3(CO)(12)H at 110 K showed a butterfly metal framework, on which the oxygen atom of the disordered mu(4)-eta(2)-CO ligand is linked to either the Ru or the Mo atom at two opposite wingtip positions, providing a unique example of isomerism involving the quadruply bridging CO ligand. These two butterfly isomers exist in solution together with a third tetrahedral isomer and undergo slow exchange with this Last isomer on the NMR time scale, as demonstrated by H-1 and C-13 NMR studies.
