Preparation and Characterization of a new metal complexes containing p-hydroxyphenyl telluriumtribromide and Triazole compounds

A new series of complexes containing p-hydroxyphenyl tellurium tribromide and triazole compound were prapared, diazonium salts of o-toluidine was reacted with piperidine to offer the corresponding triazole compound. p-hydroxyphenyl tellurium tribromide and triazole compound were reacted with copper bromide, hydrate nickel chloride zinc chloride, hydrate cobalt chloride and iron bromide in 1:2:2 mole ratio to give the transition elements complexes M[(2-CH3-C6H3-N=N)-N-C5H10)]2(4-OH-C6H4-TeBr3)2 [where M= Cu (1), Ni (2), Zn (3), Co (4) and Fe (5). The organotellurium compound and triazole were reacted with the same metal halide in 1:1:3 mole ratio to give a new series of complexes complexes M[(2-CH3-C6H3-N=N)-N-C5H10)](4-OH-C6H4-TeBr3)3 [where M= Cu (6), Ni (7), Zn (8), Co (9) and Fe (10). The I.R, 1H NMR and (C.H.N) data are reported and discussed below.
