Pyrolysis products of ligand-supported triosmium clusters
Abstract
EXAFS analysis of the pyrolysis product of [(µ-H)Os3(CO)10{µ-S[CH2]3Si(OMe)3–x(O-silica)x}] shows the average co-ordination sphere of osmium contains O, S, and Os at bonding distances in addition to carbonyl groups; in contrast there is little evidence of phosphorus co-ordination on pyrolysis of [(µ-H)Os3H(CO)10–{PPh2[CH2]2Si(OEt)3–x(O-silica)x}].
