摘要
Cr(III) complexes of the type [crCl2(NX).2H2O] and [crCl(NX)2.H2O] have been synthesised by the reaction of Cr (III) chloride with biologically active Schiff bases, viz. furfuraldehyde semicarbazone I (X=0),furfuraldehyde thiosemicarbazone (I) (X=S),indole-3-carboxaldehyde semicarbazone II (X=O) and indole-3-carboxaldehyde thiosemicarbazone (II) (X=S). These complexes have been characterized on the basis of elemental analyses and physicochemical measurements. The complexes behave as non-electrolytes and their room temperature magnetic moments correspond to three unpaired electrons. The IR spectral data reveal the bidentate chelating nature of all the ligands and the electronic spectral data indicate a tetragonal geometry. © 1990, Taylor & Francis Group, LLC.
