Diethyl 2,5-bis-[(2,3-dihydro-thieno[3,4-b][1,4]dioxin-5-yl)methyl-idene-amino]-thio-phene-3,4-dicarboxyl-ate acetone monosolvate.

ABSTRACT: The unique 3,4-ethyl-ene-dioxy-thio-phene (EDOT) unit of the title compound, C(24)H(22)N(2)O(8)S(3)·C(3)H(6)O, is twisted by 1.9?(3)° relative to the central thio-phene ring. The three heterocyclic units are anti-periplanar. In the crystal, inversion dimers linked by pairs of C-H?O hydrogen bonds connect the heterocycles. ?-? interactions occur between the central thiophene and the imine bond of the molecule [distance between the ring centroid of the ring and the azomethine bond = 3.413?(3)?Å.

The unique 3,4-ethyl-ene-dioxy-thio-phene (EDOT) unit of the title compound, C(24)H(22)N(2)O(8)S(3)·C(3)H(6)O, is twisted by 1.9 (3)° relative to the central thio-phene ring. The three heterocyclic units are anti-periplanar. In the crystal, inversion dimers linked by pairs of C-H⋯O hydrogen bonds connect the heterocycles. π-π interactions occur between the central thiophene and the imine bond of the molecule [distance between the ring centroid of the ring and the azomethine bond = 3.413 (3) Å. ...[more]
