Heart of gold (or silver) : The pseudo‐ D 2 d distorted MPd 14 cubic kernel of [(μ 14 ‐M)Pd 22 (CO) 20 (PEt 3 ) 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 Pd 10 precursor with CF 3 CO 2 H followed by coinage‐metal ion exchange of protons.
