Abstract

The first iron(II) complex of 2,5-di-(2-pyridyl)-1,3,4-thiadiazole (L), namely [FeII(L)2(NCS)2], has been synthesised and studied by magnetic susceptibility measurements, Mössbauer spectroscopy and X-ray diffraction. It has been found to undergo thermally-induced spin crossover featuring two well-separated, abrupt steps at T1/2(1) = 167 K and T1/2(2) = 112 K.
