Two new 1-(tetrazol-1-yl)cycloalkanes [C(n)tz] with n = 5 and 6 were synthesised as ligands for iron(II) spin crossover complexes. Just recently, the [Fe(C(3)tz)(6)](BF4)(2) showed that the rigid cyclopropyl-substituent of the tetrazole yielded a rather abrupt and complete spin transition at T-1/2 approximate to 190 K [1]. Aiming for a deeper insight into the factors governing the spin transition behavior such as abruptness and spin transition temperature we synthesized the two new homologous complexes [Fe(C(5)tz)(6)](BF4)(2) and [Fe(C(6)tz)(6)](BF4)(2) which were characterized by XRPD, magnetic susceptibility measurements, DSC, Fe-57-Mossbauer, UV Vis-NIR and MIR spectroscopy. The magnetic and structural properties of both [Fe(Cntz) 6](BF4) 2 with n = 5 and 6 are also compared with the [Fe(C(3)tz)(6)](BF4)(2) and its structural peculiarities are discussed.
