The crystal structure of 25,27-bis[(2-cyanophenyl)methoxy] calix[4]arene (C44H34N2O4) was determined by X-ray crystallographic analysis. It possesses space group R (3) over bar, with a = b = 35.993(8) Angstrom, c = 13.842(3) Angstrom, alpha = beta = 90degrees, gamma = 120degrees, and D-calc = 1.260 mg/cm(3) for Z = 18. Crystal data indicate that Compound 1 exists in a pinched-cone conformation with intramolecular hydrogen bonds.
