PtCl 2或PdCl 2与1，3-双（二苯基膦基）-丙烷（dppp）通过标准程序螯合分别产生络合物2和3。这些金属（II）二氯化物与AgOTf的相互作用在后处理后得到相关的三氟甲磺酸盐络合物4和5。三氟甲磺酸酯络合物4和5与等摩尔量的4，4 ′-联吡啶6在室温下在CH 2Cl 2中的反应导致形成分子盒7和8（方案1），
Chelation of PtCl2 or PdCl2 with 1, 3-bis (diphenylphosphino)-propane (dppp) by standard procedures results in complexes2 and 3, respectively. Interaction of these metal (II) dichlorides with AgOTf gives, after workup, the related triflate complexes, 4 and 5. Reaction of triflate complexes 4 and 5 with an equimolar amount of 4, 4'-bipyridine, 6, in CH2C12 at room temperature results in the formation of molecular boxes 7 and 8 (Scheme 1),
