以吡啶基邻苯二酚为配体，TiO（aca）（2）和PdCl（2）（CH（3）CN（2））为配体，构建了异源、超分子环状和笼状配合物。这两种配合物在数量上是相互转化的，其中Ti（4+）中心的配位发生在一个已知的Ti（catecholato）（3）和一个新建立的TiH（catecholato）（2）（acetylacetonato）结构之间。以Ti（4+）为中心的结构变化源于组分碱度条件的变化。
Heteronuclear, supramolecular ring and cage complexes have been constructed from a pyridyl catechol ligand, TiO(aca)(2), and PdCl(2)(CH(3)CN(2)). These two complexes are quantitatively interconvertible, in which Ti(4+) centered coordination changes take place between a well-known Ti(catecholato)(3) and a newly established TiH(catecholato)(2)(acetylacetonato) structures. The Ti(4+)-centered structural changes arise from the changes in the component fraction basicity condition.
