Rhodium cluster complexes containing bridging phenylgermanium ligands.

摘要: The reaction of Rh4(CO)12 with Ph3GeH at 97 °C has yielded the first rhodium cluster complexes containing bridging germylene and germylyne ligands:  Rh8(CO)12(μ4-GePh)6, 9, Rh3(CO)5(GePh3)(μ-GePh2)3(μ3-GePh)(μ-H), 10. When is performed under hydrogen, yield 9 increased to 42% no 10 formed. Compound contains a eight atoms arranged in form distorted cube. There are six μ4-GePh groups each face this Four have two terminal carbonyl ligands, while remaining four only one ligand. triangular three GePh3 ligand, GePh2 triply GePh also hydrido ligand that believed bridge Rh−Ge bonds. reacted PPhMe2 25 give tetraphosphine derivative Rh8(CO)8(PPhMe2)4(μ4-GePh)6, 11. structure 11 similar e...
