Synthesis in solution of high nuclearity osmium cluster species: X-ray analysis of [HOs8(CO)22]–
Abstract
Reaction of Os3(CO)12 with KOH in isobutanol has given a range of high nuclearity cluster species based on up to ten osmium atoms; in the absence of base a new cluster hydrido-monoanion [HOs8(CO)22]– is produced which, on the basis of an X-ray analysis, has been shown to possess an unusual metal core geometry that cannot be explained by conventional skeletal electron counting procedures.
