Abstract
Abstract A series of 1-(tetrazol-1-yl)alkanes [ ntz ] with n = 1–4 were synthesised as ligands for iron(II) spin crossover complexes. Within this series 1-(tetrazol-1-yl)butane [ 4tz ] was prepared for the first time, whereas 1-(tetrazol-1-yl)methane [ 1tz ], 1-(tetrazol-1-yl)ethane [ 2tz ], 1-(tetrazol-1-yl)propane [ 3tz ] and the [hexakis( ntz )iron(II)]bis(tetrafluoroborate) complexes were prepared according to the literature. Aiming for a comparative study we characterized all four compounds by XRPD, magnetic susceptibility measurements, 57 Fe-Moessbauer spectroscopy and IR spectroscopy. [Fe( 4tz ) 6 ](BF 4 ) 2 yielded appropriate single crystals and an X-ray structure of the new compound [Fe( 4tz ) 6 ](BF 4 ) 2 is presented. The magnetic and structural properties of all [Fe( ntz ) 6 ](BF 4 ) 2 are compared and discussed.
