4-[Bis(3-phenyl-1H-pyrazol-1-yl)methyl]benzene-1,2-diol
The title compound, C(25)H(20)N(4)O(2), 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...

| Sumario: | The title compound, C(25)H(20)N(4)O(2), 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⋯N hydrogen bond. As a result of these intermolecular hydrogen bonds, helical chains running along the b axis are formed. |
