Three new iron(II) spin‐crossover complexes with N 2 O 2 ‐coordinating Schiff base like equatorial ligands and alkylimidazole ligands in the axial positions were synthesised. The chain length of the alkylimidazole was varied from the previously published 1 to 5, 7 and 10 carbon atoms to investigate the influence of the alkyl chain length on the spin‐transition behaviour in solution and in the solid state. The crystal structures of [ 1 (HeptIm) 2 ] and [ 1 (DecIm) 2 ] ( 1 = Fe complex with equatorial Schiff base like ligand; HeptIm = N ‐heptylimidazole, DecIm = N ‐decylimidazole) and the packing of the molecules in the crystals are discussed.
