Heart of gold (or silver): The pseudo-D2d distorted MPd14 cubic kernel of [(μ14-M)Pd22(CO)20(PEt3)8]+ cations, with M=Au (1), Ag (2), has an encapsulated M atom (see picture; yellow) coordinated to eight cubic corner (black) and six face-capping Pd atoms (gray). Compounds 1 and 2 were obtained (28–60 % yields) from two-step/one-pot reactions of a Pd10 precursor with CF3CO2H followed by coinage-metal ion exchange of protons.
