Full TextAbstract
Two new complexes, [Co(L1)(Py)3]Cl0.75Br0.25 (L1=4-hydroxy salicylaldehyde S-allyl-isothiosemicarbazonato- N,N\',O) and [Fe(L2)Cl]·C2H5OH (L2=S-allyl-N1-(4-hydroxy salicylaldehyde)-N 4-(salicylaldehyde) isothiosemicarbazide-N,N\',O,O\'), have been synthesized and characterized by elemental analysis, FT-IR and UV–vis spectroscopy, and molar conductivity. The solid-state structures of the complexes were also determined by single crystal X-ray diffraction. The iron(III) and cobalt(III) complexes adopt distorted square-pyramidal and octahedral geometries, respectively. The strength of the bonding in these complexes was investigated by thermogravimetric studies with both exhibiting stability with complete decomposition not occurring until ca. 600 °C.
