19-Ferrocenyl-18-oxa-8,16-diazapenta-cyclo[8.6.3.01,10.0 2,7.012,16]nonadeca-2(7),3,5-triene-9,17-dione

Abstract

In the title compound, [Fe(C5H5)(C21H 19N2O3)], both pyrrol-idine rings of the pyrrolizine substructure show an envelope conformation. In the ferrocenyl moiety, the unsubstituted cyclo-penta-dienyl 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). Intra-molecular C - H⋯O inter-actions occur. The crystal packing is established through weak inter-molecular C - H⋯O and N - H⋯O inter-actions.
