7-[(3,5-Di-tert-butyl-2-hy­droxy­benzyl­idene)amino]-4-methyl-2H-chromen-2-one

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 mol­ecules in the asymmetric unit. Both mol­ecules exist in E configurations with respect to the C=N double bonds. The dihedral angles between the...

description 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 mol­ecules in the asymmetric unit. Both mol­ecules 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-hy­droxy­benzyl­idene ring planes are 4.62 (7) and 14.62 (7)° for the two mol­ecules. Intra­molecular O—H⋯N hydrogen bonding involving the O—H groups and the azomethine N atoms generate S(6) rings. In the crystal structure, independent mol­ecules are linked by C—H⋯π inter­actions, with groups of four mol­ecules stacked along the c axis.
