Transition Metal Complexes of 5-bromo Salicylaldehyde-2- furoic acid hydrazide; Synthesis and Characterisation

A series of transition metal complexes of the ligand 5-bromo salicylaldehyde-2-furoic acid hydrazide have been prepared using Ti(III), Mn(III), V(III), Co(III), Fe(III), Ru(III) and Rh(III). The complexes have been characterized by elemental analyses, melting points, molar conductance, magnetic susceptibility measurement, electronic and infra red spectral studies. Based on these studies octahedral structures have been proposed for these complexes. The ligand has behaved in dibasic tridentate manner. The I.R. spectra of the complexes revealed non-participation of furan ring oxygen in coordination with the metal ions.
