3-[(E)-(Benzyl­iminiumyl)meth­yl]-6,8-di­chloro-2H-chromen-4-olate

In the title compound, C(17)H(13)Cl(2)NO(2), the H atom of the –OH group is transferred to the N atom of the imine, forming a zwitterion. Thus, there is a intra­molecular O⋯H—N, rather than O—H⋯N, hydrogen bond, which forms a six-membered ring.
