摘要：

The molecules of 3-amino-4-anilino-1H-isochromen-1-one, C15H12N2O2, (I), and 3-amino-4-[methyl(phenyl)amino]-1H-isochromen-1-one, C16H14N2O2, (II), adopt very similar conformations, with the substituted amino group PhNR, where R = H in (I) and R = Me in (II), almost orthogonal to the adjacent heterocyclic ring. The molecules of (I) are linked into cyclic centrosymmetric dimers by pairs of N-H center dot center dot center dot O hydrogen bonds, while those of (II) are linked into complex sheets by a combination of one three-centre N-H center dot center dot center dot(O)(2) hydrogen bond, one two-centre C-H center dot center dot center dot O hydrogen bond and two C-H center dot center dot center dot pi(arene) hydrogen bonds.
