Abstract
The title compound, diethyl ),15,17,19(26),21,23-dodecaene-5,17-dicarb oxylate, C34H32O8, a tetrahydroxy calix[4]arene, adopts an open-cone c onformation in the solid state; this conformation is dictated by the p resence of intramolecular O-H...O hydrogen bonding of the phenolic OH groups [O...O 2.673 (2)-2.708 (2) Angstrom]. The planes of the aromati c rings are inclined at 120.8 (1), 133.1 (1), 118.0 (1) and 128.5 (1)d egrees to the plane of the methylene C atoms which link them. Self-inc lusion occurs when the molecules assemble in pairs about inversion cen tres.
