4-[Bis(3-phenyl-1H-pyrazol-1-yl)meth-yl]benzene-1,2-diol

The title compound, C25H20N4O2, is a ditopic ortho-hydro­quinone-based bis­(pyrazol-1-yl)methane ligand. The dihedral angles between the planes of the pyrazole rings and their attached phenyl rings are 17.4 (3) and 5.9 (
The title compound, C25H20N4O2, is a ditopic ortho-hydro­quinone-based bis­(pyrazol-1-yl)methane ligand. The dihedral angles between the planes of the pyrazole rings and their attached phenyl rings are 17.4 (3) and 5.9 (4)°. The pyrazole rings make a dihedral angle of 87.84 (16)°. One of the two hy­droxy groups forms an intra­molecular hydrogen bond to the other hy­droxy group, whereas the second is involved in an inter­molecular O—H[cdots, three dots, centered]N hydrogen bond. As a result of these inter­molecular hydrogen bonds, helical chains running along the b axis are formed.
