AB  - Molecular building blocks, capable of adopting severalstrongly deviating conformations, are of particular interest in thedevelopment of stimuli-responsive self-assemblies. The pronouncedstructural flexibility of a short acridone-based bridging ligand,equipped with two monodentate isoquinoline donors, is hereinexploited to assemble a surprisingly diverse series of coordinationdrivenPd(II) architectures. First, it can form a highly twisted Pd2L4helicate, transformable into the corresponding mesocate, controlledby temperature, counter anion and choice of solvent. Second, it alsoallows the formation of heteroleptic cages, either from a mix of ligandswith Pd(II) cations or by cage-to-cage transformation from homolepticassemblies. Here, the acridone-based ligand tolerates counterligands that carry their donors either in a diverging or convergingarrangement, as it can rotate its own coordination sites by 90° andstructurally adapt to both situations via shape complementarity. Third,by a near 180° rotation of only one of its arms, the ligand can adoptan S-shape conformation and form an unprecedented C6h-symmetricPd6L12 saw-toothed six-membered ring.
