Abstract Diethoxynitrobenzene-p-tert-butylcalix[4]arene⋅2(CH3)2C=O crystallized in the monoclinic system, space group P21/c, with cell dimensions a = 16.1437(2) Å, b = 21.0292(2) Å, c = 18.9685(3) Å and β = 110.308(1)°. The asymmetric unit consists of a diethoxynitrobenzene-p-tert-butylcalix[4]arene molecule and two solvated acetone molecules. Besides the usual CH/π interaction between p-tert-butylcalix[4]arene π cavity and a solvated acetone, this structure shows the intra- and intermolecular CH/π interactions among a nitrobenzene ring, ethylene bridge of the ethoxynitrobenzene side chain and a solvated acetone molecule.
