Kurzfassung englisch:
1-(3-halogenpropyl)-1H-tetrazoles (3-X-3tz) and their corresponding Fe(II) spin crossover complexes [Fe(3-X-3tz)6](BF4)2 will be presented in a combined experimental and theoretical study. The halogen substitution was found to positively influence the spin transition, up-shifting the transition temperature about 70 K towards room temperature in comparison to their parent compound without halogen substitution. Located in the ω-position it was shown, that the halogen is too far away from the coordinating tetrazole moiety to have an electronic impact on the spin transition. The subtle variation of a ligands steric demand within a homologous series was found to have a comparably big impact on the spin transition behavior, highlighting the sensitivity of the effect.
