杯[4]芳烃是多功能配体，能够支持形成多种包含3d、4f或3d-4f金属离子的多金属簇。基于杯芳烃的金属离子片段在这些系统中充当桥接和结构封端部分，并且这种行为在转移到双杯[4]芳烃时系统地扩展，双杯[4]芳烃是一种相对较新的配体，其中两个杯[4]芳烃被束缚在亚甲基桥位置。 N,O-配体极大地影响了双杯[4]芳烃簇的形成，提供了显着的混合价[MnMnMn]簇，该簇显示了每种配体类型典型的配位化学，而且还为后者提供了新的结构封端行为。
Calix[4]arenes are versatile ligands, capable of supporting the formation of a wide variety of polymetallic clusters comprising 3d, 4f or 3d-4f metal ions. Calixarene-based metal ion fragments act as both bridging and structure capping moieties in these systems, and this behaviour is systematically extended upon moving to bis-calix[4]arene, a relatively new ligand in which two calix[4]arenes are tethered at the methylene bridge position. N,O-Ligands greatly influence cluster formation with bis-calix[4]arene, affording a remarkable mixed-valence [MnMnMn] cluster that displays coordination chemistry typical of each ligand type, but also new structure capping behaviour for the latter.
