New platinum - Iron carbonyl cluster complexes and their reactions with alkynes
- Univ. of South Carolina, Columbia (USA)
The reaction of Pt(COD){sub 2} with Fe(CO){sub 5} has yielded the new compounds Pt{sub 3}Fe{sub 3}(CO){sub 15} (1; 9%), Pt{sub 5}Fe{sub 2}(CO){sub 12}(COD){sub 2} (2; 40%), and the known compound PtFe{sub 2}(CO){sub 8}C(D) (3; 3%). Compounds 1 and 2 were characterized by single-crystal X-ray diffraction analyses. Compound 1 contains a planar raft cluster of metal atoms consisting of a central triangle of three platinum atoms with each Pt-Pt edge bridged by a Fe(CO){sub 4} group. 1 can be reduced chemically and electrochemically to the previously known anions (Pt{sub 3}Fe{sub 3}(CO){sub 15}){sup {minus},2{minus}}. Compound 2 consists of a tetrahedral cluster of four platinum atoms with the fifth platinum atom bridging an edge of the tetrahedron and Fe(CO){sub 4} groups bridging the Pt-Pt bonds to the edge-bridging platinum atom. Compound 2 reacts with PhC{sub 2}Ph to yield the new complex Pt{sub 5}Fe{sub 2}(CO){sub 7}(CO)D({mu}{sub 3}-PhC{sub 2}Ph){sub 3}({mu}-PhC{sub 2}Ph) (4; 36%), and it reacts with PhC{sub 2}H to yield the new complex PtFe(CO){sub 3}(COD)({mu}-PhCC(H)C(H)CPh) (5; 26%).
