Abstract: In the adduct 1,2-bis(4-pyridyl)ethane-1,1,1-tris(4-hydroxyphenyl)ethane (1/2), C₁₂H₁₂N₂·2C₂₀H₁₈O₃, the bipyridyl component lies across an inversion centre in P $\overline 1$ . The tris-phenol molecules [systematic name: 4,4',4''-(ethane-1,1,1-triyl)triphenol] are linked by O-HO hydrogen bonds to form sheets built from R(38) rings, and symmetry-related pairs of sheets are linked by the bipyridyl molecules via O-HN hydrogen bonds to form open bilayers. Each bilayer is interwoven with two adjacent bilayers, forming a continuous three-dimensional structure. In the adduct 1,2-bis(4-pyridyl)ethene-1,1,1-tris(4-hydroxyphenyl)ethane-methanol (1/1/1), C₁₂H₁₀N₂·C₂₀H₁₈O₃·CH₄O, the molecules are linked by O-HO and O-HN hydrogen bonds into three interwoven three-dimensional frameworks, generated by single spiral chains along [010] and [001] and a triple-helical spiral along [100].

Formula: C₁₂H₁₂N₂·2C₂₀H₁₈O₃ and C₁₂H₁₀N₂·C₂₀H₁₈O₃·CH₄O
