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)

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 (28–6...

Description
Summary: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.
