title: 4-[(Anthracen-9-yl-methyl-idene)amino]-1,5-dimethyl-2-phenyl-1H-pyrazol-3(2H)-one.
abstract: In the title compound, C(26)H(21)N(3)O, the phenyl ring of the 4-amino-anti-pyrine group and the heterocyclic five-membered ring along with its substituents, except for the N-bound methyl group (r.m.s. deviation = 0.0027 Å), form a dihedral angle of 54.20 (5)°. Two S(6) ring motifs are formed due to intra-molecular C-H⋯N and C-H⋯O hydrogen bonds. In the crystal, mol-ecules are linked into supra-molecular chains along the a-axis direction via C-H⋯O contacts.
