Pairwise-Interwoven R⁶₆(48) Hexagonal Nets in the Hydrogen-Bonded Structure of Hexamethylenetetramine–1,1,1-Tris(4-hydroxyphenyl)ethane (1/1)

In the 1:1 adduct formed by hexamethylenetetramine (HMTA) and 1,1,1-tris­(4-hydroxyphenyl)ethane, C₆H₁₂N₄.C₂₀H₁₈O₃, the tris-phenol acts as a triple donor of hydrogen bonds of type O-H...N and the HMTA as a triple acceptor of such hydrogen bonds, with O...N distances of 2.777 (4), 2.781 (4) and 2.795 (4) Å. The components are assembled into infinite nets comprising hexagonal rings and pairs of such nets are interwoven; the pairs of interwoven nets are, in addition, connected by C-H...O hydrogen bonds with C...O distance 3.339 (5) Å.
