However, studies carried out in mixed medium [4, 10] have indicated that the presence of tetrahydrofuran (THF) in the iron (II)/azide system leads to the appearance of a more sensitive band in the absorption spectrum of these complexes, similar to the one observed for the iron(III)/azide system [15].
