Abstract

In the title compound, C17H18N4O5·0.47CH3OH, the virtually planar (r.m.s. deviation = 0.128 Å) carbonohydrazide mol-ecule is located on a twofold axis and conformation of its C=N bonds is E. There are short intra-molecular O-H⋯N hydrogen bonds between the hy-droxy groups and hydrazide N atoms. In the crystal, bifurcated N-H⋯(O,O) hydrogen bonds assemble the carbonohydrazide mol-ecules into a three-dimensional network. There are C 2 symmetric voids in this network, 47% of which are occupied by disordered methanol mol-ecules.
