In the title compound, [Fe(C5H5)(C20H13N2O2)], the substituted cyclo-penta-dienyl ring and quinoline system are approximately coplanar, making a dihedral angle of 5.18 (6)°, while the dihedral angle between the quinoline system and the benzene ring is 28.45 (8)°. There is high thermal motion in the free cyclo-penta-dienyl ring compared with the substituted cyclo-penta-dienyl ring. The conformation of the two cyclopentadienyl rings in the ferrocenyl moiety is eclipsed.

The title compound, [Fe(CH)(CHNO)], which is produced by the oxidation of 1-(4--butyl-phen-yl)-2-ethyl-3-ferrocenyl-pyrrole, crystallizes as a racemic mixture in the centrosymmetric space group 2/. The central heterocyclic pyrrole ring system subtends dihedral angles of 13.7 (2)° with respect to the attached cyclo-penta-dienyl ring and of 43.

The title compound, [Mn(CH)(CHO)]PF or [(Cht)Mn(Cp'COH)]PF, with Cht = cyclo-hepta-trienyl and Cp' = CH, is an air-stable, purple, heteroleptic, cationic sandwich complex with manganese in oxidation state +I and π-coordinating cyclo-hepta-trienyl and cyclo-penta-dienyl ligands. The latter ligand carries the carb-oxy-lic acid functionality. This 'tromancenium-8-carb-oxy-lic acid' with hexa-fluorido-phosphate as counter-ion represents a rare case of a cationic carb-oxy-lic acid.

The title ferrocene derivative, [Fe(CH)(CNO)], including an alkyne bonded to a -nitro-phenyl substituent, which was synthesized from a copper-free Sonogashira cross-coupling reaction between ethynylferrocene and 4-bromo-1-nitro-benzene, crystallizes in the 2/ space group. In the ferrocene unit, the penta-dienyl (Cps) rings are in an eclipsed conformation. The angle of rotation between the substituted cyclo-penta-dienyl ring and the -nitro-phenyl group is 6.

The structure of (μ-1κ:2(η),κ ,'-(2-{[2,6-bis(propan-2-yl)phen-yl]aza-nid-yl}eth-yl)[2-(1-inden-1-yl)eth-yl]aza-nido)(1,4,7,10,13,16-hexa-oxa-cyclo-octa-dec-ane-1κ )lithiumtin, [LiSn(CHO)(CHN)], at 100 K has monoclinic (2/) symmetry. Analysis of the coordination of the Sn to the indenyl ring shows that the Sn inter-acts in an η fashion. A database survey showed that whilst this coordination mode is unusual for Ge and Pb compounds, Sn displays a wider range of coordination modes to cyclo-penta-dienyl ligands and their derivatives.
