Abstract: Besides the cluster [Os3(u-H)(u-SbPh2)(CO)IO], 1, other products identified from the reaction of [Os3(u-H)(CO), 0(H-.CO)]~ with Ph2SbCl in THF were [Os3(u-SbPh2)2(CO)10], 2a, and a dimeric form of 1, viz. [Os3(u-H)(u-SbPh2)(CO)10]2, 3. Carrying out the reaction in CH2C12 gave 3 as the major product, while 2a has been demonstrated to result from the reaction of 1 with Ph2SbCl. In 2a the Os3Sb2 unit is almost planar; one of the Ph2Sb bridges is open while the other is closed. The two Ph2Sb-bridged Os-Os edges are shown by EXSY and variable-temperature 'H NMR spectroscopy on the analogue [Os3(CO)10(u-SbPh2){u-Sb(C6H4Me-/>)2}], 2b, to interchange via an Os-Os bond fluxion. © The Royal Society of Chemistry 2000.
