In the solid state, the title compound, C14H13NO2, crystallizes as a zwitterion. Two molecules comprise the asymmetric unit. The molecules exhibit two types of hydrogen bonds: N—H...O hydrogen bonds involving hydroxy and imine groups generate an S(6) ring motif, and O—H...O hydrogen bonds linking two symmetry‐related molecules form a centrosymmetric dimer.

The title compound, [Sn(C 6 H 5) 2 (C 8 H 6 N 2 O 2)], features a fivecoordinate C 2 NO 2 coordination geometry for Sn that is intermediate between trigonal-bipyramidal and square-pyramidal. metal-organic papers Acta Cryst.
