title: 1-[(E)-2-Formyl-1-(4-methyl-phen-yl)ethen-yl]-3-(4-methyl-phen-yl)pyrazole-4-carbaldehyde.
abstract: In the crystal structure of the title compound, C(21)H(18)N(2)O(2), mol-ecules are linked through C-H⋯O inter-actions. Two symmetry-related mol-ecules form a cyclic centrosymmetric R(2) (2)(20) dimer. These dimers are further connected into chains running along the b axis.
