The calixarene moiety in the title compound, 4,12,16,24-tetrahydroxypentacyclo­[19.3.1.13,7.19,13115,19]octacosa- 1(25),3,5,7(28),9,11,13 (27),15,17,19 (26),21,23-dodecaene methanol solvate(1:2), C28H24O4.2CH4O assumes a 1,2-alternate conformation in the crystalline state which allows two intramolecular O—H...O hydrogen bonds to be formed between pairs of adjacent phenolic OH groups. The mol­ecules are arranged in the crystal to form infinite chains connected via intermolecular hydrogen bonds involving the two bridging methanol molecules. 12-Membered cyclic arrays of six hydrogen-bonded OH groups are formed with O...O 2.618 (3)–2.742 (2) Å.
