The title compound, 5,5'-bis (acetylamino)-2, 2'-dihydroxybiphenyl,
is a minor oxidation product formed
from paracetamol. Its monohydrate, CI6HI6N204.H20,
has an extensively hydrogen-bonded crystal structure involving
N--H...O(hydroxy), (hydroxy)O---H...O(water)
and (water)O--H...O(carbonyl) interactions in a threedimensional
network, with both the oxidation product
and the water molecule lying on a twofold axis. The
two halves of the molecule have essentially the same
geometry as paracetamol in its two known anhydrous
polymorphs, except for the variation observed in the
dihedral angle between the aromatic ring and its amide
