METAL COMPLEXES OF 1,10-PHENANTHROLINE DERIVATIVES V.* BIS-LIGAND IRON(II) COMPLEXES OF 1 ,10-PHENANTHROLINE-2-CARBOTHIOAMIDE

Abstract

The preparation of 1,10-phenanthroline-2-carbothioamidea nd its bis-ligand complexes of iron(II) is described. The ligand produces a strong field and the magnetic and Mossbauer effect data for the complexes indicate that in these the metal atom has a ¹A¹ ground state. The ligand can coordinate as a neutral or anionic tridentate, producing either cationic or neutral complexes. The electronic spectra of the cationic complexes are typical for the iron(II)-bis-terimine system and show intense charge-transfer absorption. Infrared data indicate that the sulphur atom of the thioamido group is coordinated.
