Crystal structure of 1-ferrocenyl-2-(4-methyl­benzo­yl)spiro­[11H-pyrrolidizine-3,11′-indeno[1,2-b]quinoxaline]

In the title compound the four-fused-rings system is approximately planar and the pyrrolidine rings of the pyrrolidizine fragment adopt a twist conformation. In the crystal, mol­ecules are linked by C—H...O hydrogen bonds and C—H...π inter­actions, forming double-chains parallel to the c axis.
