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). Made available in DSpace on 2014-12-13T20:11:06Z (GMT).
