Physicochemical properties of the iron(II) 2-naphthalenesulfonate complex with 4-amino-1,2,4-triazole ([Fe(NH2trz)3](ns)2⋅2H2O (I)) are studied. The complex exhibits the 1A1 ↔ 5T2 spin crossover. Complex I and the initial compound for its preparation, Fe(ns)2 (II), are studied by static magnetic susceptibility, conductometry, spectrophotometry, and cyclic voltammetry methods. The μeff(T) dependence for I shows that the spin transition is abrupt both in the initial complex and in the DMF solution. Forward and inverse spin crossover temperatures are determined.
