3-(Ferrocen-1-ylcarbon­yl)-1-methyl-4-(4-methyl­phen­yl)spiro­[pyrrolidine-2,11′-indeno­[1,2-b]quinoxaline]

In the title compound, [Fe(C₅H₅)(C₃₂H₂₆N₃O)], the pyrrolidine ring adopts a twist conformation. The indeno–quinoxaline ring system [86.44 (5)°], the methyl­phenyl ring [86.06 (7)°] and the ferrocene rings [82.00 (7) and 83.95 (9)°] are almost perpendicular to the pyrrolidine ring. The two cyclopentadienyl rings adopt an eclipsed conformation. The crystal structure features C—H...N inter­actions.

3′-Ferrocenylcarbon­yl-1′-methyl-4′-phenyl­spiro­[indeno­[2,3-b]quinoxaline-11,2′-pyrrolidine]

In the title compound, [Fe(C₅H₅)(C₃₁H₂₄N₃O)], the pyrrolidine ring makes a dihedral angle of 86.3 (3)° with the mean plane [r.m.s deviation = 0.074 (2) Å] of the indeno-quinoxaline ring system. The central pyrrolidine ring adopts a twist conformation and the two cyclopentadienyl rings adopt an eclipsed conformation. In the crystal, mol­ecules are linked by weak C—H...N and C—H...π inter­actions, propagating along the c and a axes, respectively.

4-Ferrocenyl-1-methyl-3-benzoyl­spiro­[pyrrolidine-2,11′-indeno­[1,2-b]quinoxaline]

In the title compound, [Fe(C₅H₅)(C₃₁H₂₄N₃O)], the pyrrolidine ring adopts a twist conformation. The pyrrolidine ring is almost perpendicular to the indeno­quinoxaline ring system, making a dihedral angle of 84.44 (5)°. The cyclo­penta­dienyl rings of the ferrocene moiety adopt an eclipsed conformation. The crystal packing features weak C—H...N and C—H...π inter­actions.
