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 OO 2.618 (3)–2.742 (2) Å.
