(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...

| description | 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. |
