3-[2-(5-tert-Butyl-1,2-oxazol-3-yl)hydrazinyl­idene]chroman-2,4-dione

In the title compound, C(16)H(15)N(3)O(4), the dihedral angle between the chromane and isoxazole rings [r.m.s. deviations = 0.042 and 0.007 Å, respectively] is 20.33 (12)°. The mol­ecular geometry is stabilized by an intra­molecular N—H⋯O hydrogen bond. In the crystal, N—H⋯O hydrogen bonds generate...

Descripción
Sumario:In the title compound, C(16)H(15)N(3)O(4), the dihedral angle between the chromane and isoxazole rings [r.m.s. deviations = 0.042 and 0.007 Å, respectively] is 20.33 (12)°. The mol­ecular geometry is stabilized by an intra­molecular N—H⋯O hydrogen bond. In the crystal, N—H⋯O hydrogen bonds generate chains along the c-axis direction. The crystal studied was a non-morohedral twin.
