The molecular system displays a planar conformation between the phenyl and imidazo[1,2-a] pyridine rings. Weak C—H⋯π and π–π interactions as well as short contacts consolidate the three-dimensional network structure.
In the title compound, C14H15N3O2, one of the methyl C atoms of the tert-butyl group lies almost in the plane of the chromene ring system [deviation = −0.097 (2) Å], one lies above and one lies below [deviations = 1.460 (3) and 1.006 (3) Å, respectively]. The C—C—N—N torsion angle is 142.33 (17)°. In the crystal, moelcules are linked by weak C—H⋯O hydrogen bonds to generate C(6) chains propagating in the [010] direction.
In the title compound, C16H17N3O3, the chromene ring is planar, with a maximum deviation of 0.017 (4) Å for the ring O atom. The triazole and the chromene rings, bridged by a methylene C atom, are inclined to one another by 78.3 (2)°. In the crystal, methylene–triazole C—H...N hydrogen bonds lead to the formation of helical supramolecular chains along thebaxis. The sample was refined as an inversion twin. The terminal methylhydroxy group is disordered over two sets of sites [site occupancy = 0.610 (13) for the major component].
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
