(E)-3-{[([1,1′-Biphenyl]-3-ylmethyl)iminiumyl]methyl}-6,8-dichloro-2H-chromen-4-olate
In the crystal of the title compound, C(23)H(17)Cl(2)NO(2), 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 intramolecular O⋯H—N hydrogen-bonded ring, rather than that formed with an O—H⋯N hydrogen bond. The dihedral angle...
