Synthetic expertise acquired by the preparation of zero- to three-dimensional iron(II) coordination compounds based on N1-functionalized tetrazole ligands is helping to establish building principles aiming for a rational design and tunable spin switching behavior. Homologous series of halogen-substituted mononuclear complexes are evaluated with respect of electronic and steric effects on the spin transition temperature, e.g. the 3-halo-substituted propyltetrazole (3X-3tz) with X= F, Cl, Br and I (see Figure 1). Furthermore, a comparative study of polynuclear chain-type compounds with modified bridging ligand design is presented (see Figure 2) showing the impact of ligand rigidity on the spin transition behavior.
