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.

3-Methyl-4-nitro­phenol–4-dimethyl­amino­pyridine (1/1)

In the title adduct, C₇H₇NO₃^.C₇H₁₀N₂, the dihedral angle betwen the benzene ring and pyridine rings is 9.60 (8)° while the nitro group attached to the benzene ring makes a dihedral angle of 21.76 (13)°. The hydroxyl O atom deviates by 0.0247 (15) Å from the plane of the benzene ring. The crystal packing features O—H...N hydrogen bonds.
