Pd(II)与均三甲苯的络合物(1)与均三甲苯(2)反应生成两种假多态1·(2)3和1·(2)2，并观察到1·(2)3在振荡约10 S后6 h以上从1·(2)3定量转变为1·(2)2的过程。1·(2)3和1·(2)2的客体释放过程发生在正己烷中，生成1；客体插入过程发生在2中，生成1·(2)3和1·(2)2，而每个晶体都是由每种类型的离散分子构成的。这些晶体还选择性地、重复地将3个苯或1个甲苯包裹在1·(2)3和1·(2)2的均匀空腔中。相反，相应的非氟衍生物[Pd(DBM)2](DBM=二苯甲酰偏苯醚)没有客体包裹现象，表明这些显著的客体包裹是由氟取代引起的。这两个赝核的动态晶体转变和可逆客体包络都是可逆的。
Two types of pseudopolymorphs, 1·(2)3 and 1·(2)2, were obtained from Pd(II) complex (1) with mesitylene (2), and the quantitative transformation into 1·(2)2 from 1·(2)3 was observed over 6 h after shaking for approximately 10 s. The transformation was observed in both a mesitylene-rich solution and under powder conditions. The guest release processes of 1·(2)3 and 1·(2)2 occurred in hexane to yield 1, and the guest insertion processes occurred in 2 to reproduce 1·(2)3 and 1·(2)2, whereas each crystal was constructed from the discrete molecules of each type. These crystals also selectively and repeatedly encapsulated three benzenes or one toluene in the uniform cavities of 1·(2)3 and 1·(2)2. In contrast, the corresponding nonfluorinated derivative, [Pd(dbm)2] (dbm = dibenzoylmetanide), shows no guest encapsulation phenomena, indicating that the remarkable guest encapsulations are induced by fluorine substitutions. The dynamic crystal transformation and the reversible guest encapsulations of the two pseudop...
