(E,E)-3-Methyl-2,5-bis­(4-methyl­benzyl­idene)cyclo­penta­none: synthesis, characterization, Hirshfeld surface analysis and anti­bacterial activity

The title compound, (E,E)-3-methyl-2,5-bis­(4-methyl­benzyl­idene)cyclo­penta­none (MBMCP), C(22)H(22)O, was obtained by Claisen–Schmidt condensation of 4-methyl­benzaldehyde with 3-methyl­cyclo­penta­none in good yield. The structure of MBMCP was studied using UV, FT–IR and Raman spectroscopy, single-crystal X-ray diffraction (XRD) measurements, and (1)H and (13)C nuclear magnetic resonance (NMR) spectroscopy. The mol­ecular structure of MBMCP is fully extended in the E,E configuration. C—H⋯π stacking inter­actions play a significant role in the stabilization of the mol­ecular packing. Hirshfeld surface analysis was used to qu­antify the non-covalent inter­actions in the crystal lattice. Microbiological studies were performed to investigate the anti­microbial activity of this new product.
