1,3-Di(ethoxy-ethoxy-methoxy)calix[4]arene

In the solid state, the title compound, C₃₈H₄₄O₈, adopts a cone conformation, which is somewhat distorted. The cone conformation is also observed by NMR spectroscopy in solution. The distortion consists of a major inward tilt of the two opposite phenolic rings, permitting hydrogen bonding to the ether substituents.
