N′-tert-Butyl-N′-(3,5-dimethylbenzoyl)-2,2-dimethyl-4-oxochroman-6-carbohydrazide
Abstract
In the crystal structure of the title compound, C25H30N2O4, the steric size of the tert-butyl group causes the 3,5-dimethylphenyl ring to adopt a transoid geometry with respect to the N—C(O) bond. The six-membered heterocyclic ring is disordered over two sites, with occupancies of 0.553 (4) and 0.447 (4). Intramolecular C—H...O interactions are present. In the crystal, molecules are linked by intermolecular N—H...O and C—H...O hydrogen bonds.
