19-Ferrocenyl-18-oxa-8,16-diazapentacyclo[8.6.3.01,10.02,7.012,16]nonadeca-2(7),3,5-triene-9,17-dione

Abstract

In the title compound, [Fe(C5H5)(C21H19N2O3)], both pyrrolidine rings of the pyrrolizine substructure show an envelope conformation. In the ferrocenyl moiety, the unsubstituted cyclopentadienyl ring is disordered over two orientations with site occupancies of 0.64 (2) and 0.36 (2). In the pyrrolizine ring, one C atom is disordered over two positions, with site occupancies of 0.71 (1) and 0.29 (1). Intramolecular C—H...O interactions occur. The crystal packing is established through weak intermolecular C—H...O and N—H...O interactions.
