摘要：

Two types of arrays are formed in water involving aza-crown ethers, p-sulfonatocalix[5] arene and europium(III) ions. One is a co-ordination polymer connecting calixarenes, sodium ions and lanthanide ions based on 'ferris wheel' moieties incorporating aza-18-crown-6 and sodium ions. The second structure is a host-guest arrangement with di-protonated diaza-18-crown-6 in the cavity of the calixarenes as part of secondary coordination spheres of aquated europium(III) ions.
