4-{[4-(Dimethylamino)benzylidene]-amino}-1,5-dimethyl-2-phenyl-1H-pyrazol-3(2H)-one.

ABSTRACT: The azomethine double-bond in the title Schiff base, C(20)H(22)N(4)O, has an E-configuration. The aromatic ring of the benzyl-idene portion (r.m.s. deviation 0.011?Å) and the five-membered pyrazolyl ring (r.m.s. deviation 0.033?Å) form a dihedral angle of 19.0?(1)°. The phenyl substituent is twisted by 55.0?(1)° with respect to the five-membered ring.

The azomethine double-bond in the title Schiff base, C(20)H(22)N(4)O, has an E-configuration. The aromatic ring of the benzyl-idene portion (r.m.s. deviation 0.011 Å) and the five-membered pyrazolyl ring (r.m.s. deviation 0.033 Å) form a dihedral angle of 19.0 (1)°. The phenyl substituent is twisted by 55.0 (1)° with respect to the five-membered ring. ...[more]
