1-Acetyl-5-ferrocenyl-3-phenyl-2-pyrazoline
Abstract
In the title compound, [Fe(C5H5)(C16H15N2O)], the pyrazoline ring and the phenyl ring are nearly coplanar, making a dihedral angle of 6.54 (2)°, while the substituted cyclopentadienyl ring is twisted out of the pyrazoline ring plane by 81.32 (1)°. The molecules in the crystal structure are held together by weak C—H...O intermolecular hydrogen bonds and two C—H...π interactions.
