چکیده
In the title compound, C(16)H(13)NO(2), the two benzene rings make a dihedral angle of 55.5 (2)°. The crystal packing is stabilized by inter-molecular C-H⋯O hydrogen bonds and weak π-π stacking inter-actions [centroid-centroid distance = 3.595 (3)Å], linking the mol-ecules into ladders of inversion dimers.

In the isoquinoline ring system of the title mol-ecule, C(22)H(20)N(2)O(5), the N-heterocyclic ring is in a half-boat conformation. The least-squares plane of the dioxa-2-aza-spiro ring [maximum deviation = 0.076 (1) Å] and forms a dihedral angle of 14.54 (4)° with the phenyl ring. In the crystal, mol-ecules are linked via inter-molecular C-H⋯O hydrogen bonds into layers parallel to (100).
