1-Acetyl-5-ferrocenyl-3-phenyl-2-pyrazoline

Abstract

In the title compound, [Fe(C(5)H(5))(C(16)H(15)N(2)O)], the pyrazoline ring and the phenyl ring are nearly coplanar, making a dihedral angle of 6.54 (2)°, while the substituted cyclo-penta-dienyl ring is twisted out of the pyrazoline ring plane by 81.32 (1)°. The mol-ecules in the crystal structure are held together by weak C-H⋯O inter-molecular hydrogen bonds and two C-H⋯π inter-actions.
