摘要：

The structures of bridged calix[6]arenes 1a and 1b were investigated. Whereas 1a was found to take a structure where the bridging unit lies below the calix[6]arene macroring with a cone conformation, its tetramethyl ether 1b adopts the 1,2,3-alternate conformation with the central bromide functionality pointing into the cavity, as revealed by X-ray crystallographic analysis.
