Abstract
In the crystal of the title compound, C16H10N4O6, the dinitrophenyl and hyd
roxyphenyl groups are oriented at angles of 43.8(1) and 28.0(1)degrees, res
pectively, with respect to the pyrazole ring. The internal C-C-C ring angle
s at the o- and p- positions, where NO2 is bonded, are 121.6(2) and 122.3(2
)degrees. The crystal structure and packing are stabilized by O-H ... N and
C-H ... O hydrogen bonds.
