(Z)-6-[(2-Fluorophenyliminio)methylene]2,3-dihydroxyphenolate

Abstract

The title compound, C13H10FNO3, crystallizes in a zwitterionic form. The dihedral angle between the aromatic rings is 21.69 (9)degrees. O-H center dot center dot center dot O hydrogen bonds generate a centrosymmetric R-2(2)(10) dimer and the dimers are linked by O-H center dot center dot center dot O hydrogen bonds into sheets parallel to (10 (1) over bar).
