2-(Benz-yloxy)iso-quinoline-1,3(2H,4H)-dione.

Yoshinobu Ishikawa1, Soichiro Matsuo.   

Abstract

The title compound, C16H13NO3, exists in the keto form and the iso-quinoline system is essentially planar (mean deviation = 0.0424 Å). The dihedral angle between the aromatic rings is 4.2 (2)°. In the crystal, mol-ecules are linked via weak C-H⋯O hydrogen bonds and C-H⋯π inter-actions, forming a three-dimensional structure.

Refinement. Refinement was performed using all reflections. The weighted R-factor (wR) and goodness of fit (S) are based on F2. R-factor (gt) are based on F. The threshold expression of F2 > 2.0 σ(F2) is used only for calculating R-factor (gt).
