In 1,1,1-tris(4-hydroxyphenyl)ethane–1,2-diaminoethane (2/1), [CH3C(C6H4OH)3]2.H2NCH2CH2NH2 (1), triclinic, P1, with Z = 2, a = 10.9430 (12), b = 11.1075 (12), c = 15.249 (2) Å, α = 98.672 (15), β = 96.312 (10), γ = 98.377 (13)°, the tris-phenol units form continuous two-dimensional nets, built from pseudo-hexagonal rings, interwoven pairs of which are cross-linked by the 1,2-diaminoethane units. Each tris-phenol unit acts as a triple donor, forming two O—HO and one O—HN hydrogen bonds, and as a double acceptor in two O—HO hydrogen bonds: the diamine unit, in which the CH2 groups are disordered over two sets of sites with site-occupation factors of 0.740 (5) and 0.260 (5), respectively, acts as a double acceptor only and the N—H bonds play no role in the hydrogen bonding. The OO distances in the O—HO hydrogen bonds are 2.642 (2), 2.690 (2), 2.810 (2) and 2.835 (2) Å, and the two independent ON distances are both 2.665 (3) Å. Adjacent bilayers are connected into a continuous three-dimensional array by C—HO hydrogen bonds, all having a CO distance of 3.468 (4) Å.
