5''-(4-Nitro-benzyl-idene)-7'-(4-nitro-phen-yl)-1''-methyl-1',3',5',6',7',7a'-hexa-hydro-dispiro-[ace-naphthyl-ene-1,5'-pyrrolo-[1,2-c][1,3]thia-zole-6',3''-piperidine]-2,4''(1H)-dione including an unknown solvate.

ABSTRACT: The title compound, C35H28N4O6S, crystallizes with two mol-ecules in the asymmetric unit. In both mol-ecules, the piperidine ring adopts a shallow-chair conformation, the thia-zole ring adopts a twisted conformation about the Cm-N bond (m = methine) and the pyrrole ring adopts an envelope conformation with the C atom shared with the thia-zole ring as the flap. In the crystal, inversion dimers linked by pairs of C-H?O inter-actions generate R 2 (2)(34) loops for one of the asymmetric mol-ecules. Further C-H?O links also involving the other mol-ecule lead to a three-dimesional network. The contribution of the highly disordered solvent to the scattering was removed with SQUEEZE option of PLATON [Spek (2009 ?). Acta Cryst. D65, 148-155]. The solvent contribution is not included in the reported mol-ecular weight and density.
