(,)-3-Methyl-2,5-bis-(4-methyl-benzyl-idene)cyclo-penta-none: synthesis, characterization, Hirshfeld surface analysis and anti-bacterial activity.

The title compound, (,)-3-methyl-2,5-bis-(4-methyl-benzyl-idene)cyclo-penta-none (MBMCP), CHO, was obtained by Claisen-Schmidt condensation of 4-methyl-benzaldehyde with 3-methyl-cyclo-penta-none in good yield. The structure of MBMCP was studied using UV, FT-IR and Raman spectroscopy, single-crystal X-ray diffraction (XRD) measurements, and H and C nuclear magnetic resonance (NMR) spectroscopy. The mol-ecular structure of MBMCP is fully extended in the , configuration. C-H⋯π stacking inter-actions play a significant role in the stabilization of the mol-ecular packing. Hirshfeld surface analysis was used to qu-antify the non-covalent inter-actions in the crystal lattice. Microbiological studies were performed to investigate the anti-microbial activity of this new product.
