The furan ring in the title compound, C27H20N2O2, adopts a twisted conformation about the sp3—sp3 bond. The molecular structure is stabilized by an intramolecular C—HO interaction which generates an S(6) ring motif. The crystal packing is stabilized by N—HO and C—HO interactions generating centrosymmetric R22(18) and C(6) chain motifs, respectively. A weak C—Hπ interaction is also observed.

The furan ring in the title compound, C26H18N2O2, is twisted about the C(H)—C(H) bond. The molecular structure is stabilized by an intramolecular C—HO interaction, which generates an S(6) ring motif. The presence of N—HN hydrogen bonds leads to inversion dimers, which are stabilized in the crystal packing by C—HO and C—Hπ interactions, forming layers that stack along the a axis.

The furan ring in the title compound, C26H17BrN2O2, adopts a twisted envelope conformation. The molecular structure is stabilized by an intramolecular C—HO interaction which generates an S(6) ring motif. The crystal packing is stabilized by N—HO and C—HBr interactions, generating an R22(16) ring motif and a C(12) linear chain motif, respectively. Weak C—Hπ bonding is also observed.

In the title compound, C29H24N2O2, the hydrofuran ring is twisted with puckering parameters Q = 0.1553 (16) Å and φ = 305.0 (6)°. In the crystal, the graph-set motifs of the interaction pattern are an R22(16) motif involving dimers through N—HN hydrogen bonds across centres of inversion and a C(6) motif through C—HO hydrogen-bond between glide-related molecules. Together, these generate [101] ladder-like chains.
