摘　　要：Using coinage metal （Cu（Ⅱ）, Ag（Ⅰ）） hinges, two sets of heterometallic molecular capsules with analogous open-ended cavities were prepared based on the half-sandwich rhodium fragments. In the case of [Rh4Cu4] cages, up to six-fold-stacked host-guest structures were formed by varying the cavity＇s dimensions. Moreover, the series of capsules were demonstrated to self-fine-tune to form multi-heteroguest arrays via favourable donor-acceptor interactions and Ag-π interactions, as evidenced from single-crystal X-ray analysis.Using coinage metal （Cu（Ⅱ）, Ag（Ⅰ）） hinges, two sets of heterometallic molecular capsules with analogous open-ended cavities were prepared based on the half-sandwich rhodium fragments.
