Diethyl 2-[(1-methyl-1H-pyrrol-2-yl)methyl-ene-amino]-5-(2-thienylmethyl-ene-amino)thio-phene-3,4-dicarboxyl-ate.

ABSTRACT: Both imine bonds of the title compound, C(21)H(21)N(3)O(4)S(2), were found to be in the E configuration. The terminal pyrrole and thio-phene rings are twisted by 2.5?(3) and 2.3?(2)°, respectively, from the mean plane of the central thio-phene to which they are attached. The structure is disordered by exchange of the terminal heterocyclic rings; the site occupancy factors are ca 0.8 and 0.2. The crystal packing involves some ?-? stacking [3.449?(4)?Å between pyrrole and terminal thio-phene rings].

Both imine bonds of the title compound, C(21)H(21)N(3)O(4)S(2), were found to be in the E configuration. The terminal pyrrole and thio-phene rings are twisted by 2.5 (3) and 2.3 (2)°, respectively, from the mean plane of the central thio-phene to which they are attached. The structure is disordered by exchange of the terminal heterocyclic rings; the site occupancy factors are ca 0.8 and 0.2. The crystal packing involves some π-π stacking [3.449 (4) Å between pyrrole and terminal thio-phene rings  ...[more]
