Abstract

SYNTHESIS, STRUCTURE AND PROPERTIES OF IRON COORDINATION COMPOUNDS WITH 2-ACETYLPYRIDINE 4-PHENYLTHIOSEMICARBAZONE AND DERIVATIVES

The synthesis, crystallographic and magnetic studies of Fe(III) compounds with 4-phenylthiosemicarbazone and 4- phenylthiosemicarbazone 2-acetylpyridine are presented. The spectrophotometric studies in solution were realized for Fe(II) ions with the same ligands. The coordination compounds [Fe(L1)2]BF4·CH3OH (1) and [Fe(L2)2]FeCl4 (2) were obtained from alcoholic solutions. Crystallographic studies reveal that the methylation of sulfur atom influence the coordination set on the Fe(III) ion. Compounds 1 and 2 shows different magnetic properties in function of temperature. Keywords: coordination compound, iron, magnetic properties.
