(E)-3-(4-Methyl­phen­yl)-3-[3-(4-methyl­phen­yl)-1H-pyrazol-1-yl]-2-propenal

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...

Descripción
Sumario: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. Inter­molecular C—H⋯O hydrogen bonds connect mol­ecules into cyclic centrosymmetric R (2) (2)(26) dimers, which are cross-linked via C—H⋯π inter­actions.
