Crystal structure and Hirshfeld surface analysis of a pyrrolo-thia-zine complex.

In the title compound, diethyl 2,2-dioxo-4-(thio-phen-2-yl)-1-[(thio-phen-2-yl)meth-yl]-3,4,6,7,8,8a-hexa-hydro-1H-pyrrolo-[2,1-c][1,4]thia-zine-1,3-di-carboxyl-ate, C(22)H(28)NO(6)S(3), the pyrrolo ring is in an envelope conformation while the thia-zine ring adopts a near chair conformation. The dihedral angles between the thia-zine ring and the methyl-thienyl, thienyl and pyrrolo rings are 64.0†(2), 87.92†(7) and 5.6†(2)°, respectively. In the crystal, the mol-ecules are linked by weak C-H⋯O hydrogen bonds. A Hirshfeld surface analysis was performed to investigate the inter-molecular inter-actions. Disorder of the methyl-thienyl group with site occupancies of 0. 792†(3) and 0.208†(3) is observed.
