3-(4-Bromophenyliminomethyl)benzene-1,2-diol

“…1. Unlike the recently published structure of 4-({[(E)-(2,3-dihydroxyphenyl)methylidene]amino}methyl)cyclohexane carboxylic acid (Shuja et al, 2006), also synthesized from 2,3dihydroxybenzaldehyde, compound (I) does not crystallize as a zwitterion. Two aromatic rings, C1-C6 and C8-C13, form a dihedral angle of 49.02 (10) .…”
