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. ...[more]
