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.
金（或银）心：(μ14-M)Pd22(CO)20(PEt3)8阳离子的伪-D2d 扭曲的 MPd14 立方核，其中 M = Au（1），Ag（2），具有被包裹的 M 原子（见图片；黄色）与八个立方角（黑色）和六个面封 Pd 原子（灰色）配位。化合物 1 和 2 通过 Pd10 前体与 CF3CO2H 的两步/一锅反应以及金属硬币离子对质子的交换得到（产率为 28-60%）。
