Discussion The six-membered ring (CI to C6) containing a double bond C2=C3 adopts a distorted half chair conformation with dihedral angles ranging from 1.8° (C1-C2-C3-C4) up to 56.0° (C4-C5-C6-C1). The phenyl group is twisted about 50.4° related to the plane defined by the carbon atoms CI, C2 and C3. As shown in the figure, two molecules form a centrosymmetric dimer with a central planar six-membered ring containing two N-O-H units hold together by two Ν—Η hydrogen bonds (
