Abstract
This invention relates to new bimetallic cluster compounds of the formula L.sub.2 M.sub.2 Ru.sub.6 C(CO).sub.16 wherein L is RCN, R being C.sub.1 to C.sub.6 alkyl, C.sub.6 to C.sub.10 aralkyl or phenyl, and M is copper, silver or gold. These compounds are useful as homogeneous catalysts for converting synthesis gas to methanol.
Claims7
A composition of matter comprising a bimetallic cluster compound of the formula
- L.sub.2 M.sub.2 Ru.sub.6 C(CO).sub.16
- where L is RCN, R being C.sub.1 to C.sub.6 alkyl, C.sub.6 to C.sub.10 aralkyl or phenyl and M is copper, silver or gold.
A composition of matter comprising the compound (CH.sub.3 CN).sub.2 Cu.sub.2 Ru.sub.6 C(CO).sub.16.
A process for preparing bimetallic cluster compounds of the formula L.sub.2 M.sub.2 Ru.sub.6 C(CO).sub.16 where L is RCN, R being C.sub.1 to C.sub.6 alkyl, C.sub.6 to C.sub.10 aralkyl or phenyl, and M is copper, silver or gold, which comprises reacting a solution of a ruthenium carbide cluster anion of the formula [Ru.sub.6 C(CO).sub.16 ].sup.2- wherein the corresponding cation is alkali metal, alkaline earth metal, N(R').sub.4.sup.+, P(R').sub.4.sup.+ or As(R').sub.4.sup.+ where R' is alkyl or aryl, with a Group Ib metal cation of the formula M(L.sub.4).sup.+ ;
