title: Ion exchange of protons by coinage metals to give gold and silver encapsulation within a pseudo-D2d distorted face-capped Pd14 cubic kernel: [(μ14-M)Pd22(CO)20(PEt3)8]+ (M = Au, Ag).
abstract: 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 CF3CO2 H followed by coinage-metal ion exchange of protons.
