| description | In the first of the compounds reported herein, namely 6′-ferrocenyl-6a′-nitro-6′,6a′,6b′,7′,9′,11a′-hexahydro-2H-spiro[acenaphthylene-1,11′-chromeno[3′,4′:3,4]pyrrolo[1,2-c]thiazol]-2-one, [Fe(C5H5)(C29H21N2O4S)], (I), the thiazolidine ring adopts a twist conformation on the methine N—C atoms. In the second compound, viz. 6′-(4-methoxyphenyl)-6a′-nitro-6′,6a′,6b′,7′,9′,11a′-hexahydro-2H-spiro[acenaphthylene-1,11′-chromeno[3′,4′:3,4]pyrrolo[1,2-c]thiazol]-2-one, [Fe(C5H5)(C26H19N2O5S)], (II), the thiazolidine ring adopts an envelope conformation with a methine C atom as the flap. In both compounds, the pyrrolidine ring adopts a twist conformation on the thiazolidine and tetrahydropyran C atoms. The mean planes of the thiazolidine and pyrrolidine rings subtend angles of 67.30 (1) and 62.95 (7)° in (I) and (II), respectively, while the mean plane of the pyrrolidine ring makes dihedral angles of 76.53 (1) and 87.74 (7)° with the acenaphthylene ring system in (I) and (II), respectively. In both compounds, an intramolecular C—H...O hydrogen bond forms an S(7) ring motif. In the crystal of (I), molecules are linked via two different C—H...O hydrogen bonds, forming chains along [001] and [100]. In (II), they are linked through C—H...O hydrogen bonds, forming dimers with an R22(10) ring motif while C—H...π interactions link the molecules in a head-to-tail fashion, forming chains along the a-axis direction. |
