Lg. Lavrenova et al., SPIN-CROSSOVER AND THERMOCHROMISM IN COMPLEXES OF IRON(II) IODIDE ANDTHIOCYANATE WITH 4-AMINO-1,2,4-TRIAZOLE, Polyhedron, 14(10), 1995, pp. 1333-1337
New complexes of iron(II) iodide and thiocyanate with 4-amino-1,2,4-tr
iazole were synthesized. The complexes were characterized by magnetic
measurements, reflection, Mossbauer and IR spectra. The coordination o
f iron(II) is discussed on the basis of these data. The compounds poss
ess reversible thermochromism (colour change from white to pink) due t
o the spin transition T-5(2) reversible arrow(1)A(1).
