4-{(E)-[(2-Hydroxynaphthalen-1-yl)methylidene]amino}-1,5-dimethyl-2-phenyl-2,3-dihydro-1H-pyrazol-3-one: a new polymorph (β-phase)
The title molecule, C22H19N3O2, is a new polymorphic modification, viz. the β-phase; the α-phase has been previously published [Liang & Wang (2010). Acta Cryst. E66, o1968–o1969]. In the crystal of the β-phase, the molecules pack in helical chains generated by C—H...O hydrogen bonds and offset π...
