Ferromagnetic FeSe₂ from a mixed sulphur-selenium complex of iron [Fe{(SePPh₂NPPh₂S)₂N}₃] through pyrolysis.

ABSTRACT: Iron (III) thioselenoimidodiphosphinate complex, Fe{(SePPh₂NPPh₂S)₂N}₃], was synthesized from the ligand [Ph₂P(S)HNP(Se)Ph₂], and the complex employed as the combined source of the targeted elements (Fe and Se) to generate orthorhombic FeSe₂. This was achieved by thermolysis using a quartz glass tube, under reduced pressure at 500 °C during 1 h 30 min. The crystalline product was revealed by X-ray diffraction (XRD), while the morphology consisted of polygonal crystallites according to the scanning electron microscopy (SEM) studies. Superconducting quantum interference device (SQUID) measurements on the material confirmed its ferromagnetism as observed from the magnetization curve, indicated by the field-cooled and
