Bottom Line: Both mol-ecules exist in E configurations with respect to the C=N double bonds.The dihedral angles between the coumarin and 3,5-di-tert-butyl-2-hy-droxy-benzyl-idene ring planes are 4.62 (7) and 14.62 (7)° for the two mol-ecules.Intra-molecular O-H⋯N hydrogen bonding involving the O-H groups and the azomethine N atoms generate S(6) rings.

ABSTRACT
The title compound, C(25)H(29)NO(3), is a Schiff base derivative of coumarin 120. There are two structurally similar but crystallographically independent mol-ecules in the asymmetric unit. Both mol-ecules exist in E configurations with respect to the C=N double bonds. The dihedral angles between the coumarin and 3,5-di-tert-butyl-2-hy-droxy-benzyl-idene ring planes are 4.62 (7) and 14.62 (7)° for the two mol-ecules. Intra-molecular O-H⋯N hydrogen bonding involving the O-H groups and the azomethine N atoms generate S(6) rings. In the crystal structure, independent mol-ecules are linked by C-H⋯π inter-actions, with groups of four mol-ecules stacked along the c axis.
