Methyl 2‐[(ferrocenylcarbonyl)amino]thiophene‐3‐carboxylate

The title compound, [Fe(C 5 H 5 )(C 12 H 10 NO 3 S)], was synthesized from ferrocenecarboxylic acid and methyl 2‐aminothiophene‐3‐carboxylate in modest yield. The substituted ring system is essentially planar through the amidothienylcarboxylate moiety, η 5 ‐(C 5 H 4 )CONH(C 4 H 2 S)CO 2 Me, with the amido unit at an angle of 3.60 (7)° to the five‐atom thienyl group, which is oriented at an angle of 3.17 (7)° to the ester moiety. The primary hydrogen bond is an intramolecular N—H⋯O=C carboxylate interaction [N⋯O 2.727 (2) Å], and the main intermolecular hydrogen bond involves a thienyl carboxylate and the carboxylate of a symmetry‐related molecule [C⋯O 3.443 (3) Å].
