Abstract: | The metal hydride coupling reaction, which has been used here to produce mixed metal clusters, is dependent upon the HRe(CO)(,5) unit initially serving as a two-electron donor to the lightly stabilized clusters Os(,3)(CO)(,12-x)S(,x) (S = CH(,3)CN, C(,8)H(,14); x = 1 or 2). From this point, all that is necessary to achieve the final structures of HReOs(,3)(CO)(,16) and H(,2)Re(,2)Os(,3)(CO)(,20) is for an oxidative addition to take place. These two compounds are related by a third, lightly stabilized species, HReOs(,3)(CO)(,15)(CH(,3)CN). It has been found that the open-molecular structure of this lightly stabilized species may be transformed to a closed structure either by heating in the presence of H(,2) or by treating with Me(,3)NO(.)2H(,2)O in the presence of H(,2). The product of this closure process is H(,5)ReOs(,3)(CO)(,12). |
