- Abstract
Two α,β-unsaturated ketones: CHNO ( 1), ( E)-3-(4-(1 H-benzo[d]imidazol-1-yl)phenyl)-1-phenylprop-2-en-1-one and CHNO ( 2), ( E)-3-(4-(1 H-pyrazol-1-yl)phenyl)-1-(4-methoxyphenyl)prop-2-en-1-one were synthesized and characterized by X-ray diffraction analyses, EA, H NMR-, and IR-spectra. In the crystal structure of 1, molecules are linked through intermolecular hydrogen bonds, C-H⋯π and π⋯π interactions forming a 3-D network, while in the crystal structures of 2, molecules are assembled by the C-H⋯O, C-H⋯N hydrogen bonds and C-H⋯π interactions into an infinite 3-D supramolecular structure. A particularly interesting feature of the packing in the structure of 2, is the extensive contribution of C-H⋯π interactions, involving two hydrogen atoms from each of the methyl groups of the methoxy substituents.
