Crystal structure, Hirshfeld surface, DFT, mol-ecular docking of 1-[(6--butyl-2-oxo-2-chromen-4-yl)meth-yl]-4,4-di-methyl-piperidine-2,6-dione and cytotoxic effects on breast cancer (MDA-MB 231), human alveolar basal epithelial (A549) cell lines.

The title compound, CHNO, was synthesized by S2 reaction of bromo-methyl coumarin with 4,4-di-methyl-piperidine-2,6-dione. The mol-ecule crystalizes in the monoclinic system with space group 2/. The coumarin unit is almost planar with a dihedral angle between the aromatic rings of 0.
