(E)-3-Phenyl-3-(3-phenyl-1H-1-pyrazolyl)-2-propenal

Abstract

In the title compound C18H14N2O, the pendant rings make dihedral angles of 66.1 (1)° and 13.9 (1) with the central ring. In the crystal, two mol-ecules form a cyclic centrosymmetric R22(22) dimer through pairs of C - H⋯O bonds. These dimers are further connected into zigzag chains extending along the b axis through C - H⋯π and C - H⋯O inter-actions.
