The title compounds, C10H8N2·C15H16O2 (1) and C10H8N2·C14H10O5 (2), were synthesized by 4,4′-bipyridyl and two similar V-shaped molecules. The two complexes both crystallized in the same space group P21/n with the crystal cell parameters: a = 16.0536(3) Å, b = 6.42730(1) Å, c = 21.2717(4) Å, β = 102.330°, V = 2144.21(7) Å3, Z = 4 in compound 1 and a = 7.45020(10) Å, b = 10.0784(2) Å, c = 26.9430(5) Å, β = 92.1140(10)°, V = 2021.67(6) Å3, Z = 4 in compound 2. Compound 1 forms regular molecular chains containing alternative 4,4′-bipyridyl and 4,4′-isopropylidenediphenol units; the molecular components are linked by two types of O–H···N hydrogen bonds. Additionally, every two neighboring chains are connected to be a ladder structure by means of weak C–H···O interactions. In compound 2, 4,4′-bipyridyl and 4,4′-oxydibenzoic acid first construct one-dimensional architecture by strong O–H···N hydrogen bonds, which are similar with the interactions in compound 1. Secondly, two types of weak C–H···O contacts formed between 4,4′-bipyridyl and the acid link one-dimensional chains to be interlaced three-dimensional hydrogen-bonded networks.Compounds C10H8N2·C15H16O2 (1) and C10H8N2·C14H10O5 (2), were synthesized by 4,4’-bipyridyl and two similar V-shaped molecules. Compound 1 forms regular molecular chains containing alternative 4,4’-bipyridyl and 4,4’-isopropylidenediphenol units which are linked with O–H…N hydrogen bonds, and two neighboring chains are joined to be a ladder structure by weak C–H…O interactions. Similarly, 4,4’-bipyridyl and 4,4’-oxydibenzoic acid of 2 are also connected by O–H…N hydrogen bonds, but different C–H…O interactions link one-dimensional chains to be three-dimensional interlaced hydrogen-bonded networks.
