(E)-3-(4-Methyl-phen-yl)-3-[3-(4-methyl-phen-yl)-1H-pyrazol-1-yl]-2-propenal.

ABSTRACT: In the title compound, C(20)H(18)N(2)O, the pyrazole ring adopts a planar conformation. The C-N bond lengths in the pyrazole ring are shorter than a standard C-N single bond (1.443 Å), but longer than a standard double bond (1.269 Å), indicating electron delocalization. The propenal group assumes an extended conformation. Inter-molecular C-H⋯O hydrogen bonds connect mol-ecules into cyclic centrosymmetric R(2) (2)(26) dimers, which are cross-linked via C-H⋯π inter-actions.
