(E)-3-{[([1,1'-Biphen-yl]-3-ylmeth-yl)iminium-yl]meth-yl}-6,8-di-chloro-2H-chromen-4-olate.

ABSTRACT: In the crystal of the title compound, C23H17Cl2NO2, the H atom of the -OH group is transferred to the N atom of the imine, forming a zwitterion. This results in a six-membered intra-molecular O⋯H-N hydrogen-bonded ring, rather than that formed with an O-H⋯N hydrogen bond. The dihedral angle between the rings of the biphenyl unit is 13.88 (10)°. In the crystal, mol-ecules are linked by N-H⋯O and C-H⋯O inter-actions.
