The molecules of 3-tert-butyl-5-[(4-methoxybenzyl)amino]-1phenyl-1H-pyrazole, C21H25N3O, are linked into simple C( 9) chains by a single C-H center dot center dot center dot N hydrogen bond. 5-[(Benzotriazol-1-ylmethyl)(4-methoxybenzyl)amino]-3-tert-butyl-1-phenyl1H-pyrazole, C28H30N6O, crystallizes with Z' = 2 in the space group P2(1)/c. The molecules are weakly linked into centrosymmetric tetramolecular aggregates by a combination of C-H center dot center dot center dot N and C-H center dot center dot center dot O hydrogen bonds.
