Synthesis and Spectroscopic Studies of Carbonate bis- trimethylenediamine Cobalt(III) Nitrate ([Co(co3(tn)2] NO,.5H2O)

Carbonate bis-trimethylenediamine Cobalt(III) Nitrate 1.5hydrate ([Co(CO3tn]. NO3 1.5H20) complex was prepared using cobalt(II) nitrate six hydrate [Co(NO3)2]-6H2O and trimethylenediamine in presence of hydrogen peroxide. The prepared complex was characterized by measuring the percentage of cobalt and water as well as by using thermogravimetric analysis, 13C - NMR and UV-VIS, IR spectra
