Abstract
Novel bimetallic cluster compounds of the formula [M].sub.n [(Ru.sub.6 C(CO).sub.16).sub.2 L] where M is a cation, L is Tl, In or Ga, and n is a number which satisfies valence requirements. These compounds are useful as homogeneous and heterogeneous catalysts for converting synthesis gas to organic compounds.
