Synthesis and x-ray chracterization of the dianions trihydridodecacarbonyltrirhenate(2-)and trihydrido-\u3bc3-oxoenneacarbonyltrirhenate(2-)

The synthesis of the new anions [H3Re3(CO)10]2- and [H3Re3(\u3bc3-O)(CO)9]2-, obtained from [H4Re4(CO)15]2-, and their characterization by IR, NMR and X-ray analyses are reported; both species contain a triangular metal atom cluster and the former, which is electron deficient, contains a ReRe double bond. ca]To whom correspondence should be addressed. \ua9 1976
