In the title compound, C 23 H 19 ClN 2 O 3 S, the central pyrimidine ring is significantly puckered, assuming an intermediate conformation between an envelope and a screw-boat form. Short intermolecular C-HÁ Á ÁO, C-HÁ Á Á andstacking interactions contribute to the stability of the crystal packing.
The structure of the title compound [systematic name: -5,5 H -dicarboxylate], C 33 H 37 ClN 2 O 4 , was determined by single-crystal X-ray diffraction at 130 K. In the crystal structure, the compound forms hydrogen-bonded dimers. The two pyrrole H atoms are bonded to one carbonyl O atom of a symmetr
The title compound, C~25~H~24~N~2~O~3~S~3~, was crystallized from a methanol–acetone mixture. The monoclinic structure features one molecule in the asymmetric unit. The crystal packing is stabilized by π stacking.
