New palladium cluster compounds. X-Ray crystal structure of Pd10(CO)12(PBu3n)6

The ten-vertex palladium cluster Pd10(CO)12[PBun3]6 obtained by treatment of Pd(OAc)2 with PBun3 and CO [molar ratio Pd : P 1 : 4·5], is shown by X-ray crystallography to contain a tetracapped octahedron of metal atoms, i.e. a distorted fragment of close packing Pd10 with 16 skeletal electrons.
