Three co-ordinate mercury (I) complexes of variedly substituted modobasic bidentate/tridentate triazene-1-oxides (TH) and dibasic tridentate triazene-1-oxides (T*H2) have been characterised. Attempt to raise the co-ordination number using monodentate and bidentate secondary ligands have been unsuccessful. In all the cases complexes conform to the stoichiomestry Hg2T2 for monobasic ligands and Hg2T' for the dibasic ligands. I. R. evidences support bonding through both N-, nitrogen and N-.O, oxygen of the triazene-1 -oxides. The preference of mercury (I) for linear coordination on the one hand and the three co-ordinate nature of mercury (I) chelates in the case of Hg2T2 and Hg2T L (L=Monodentate ligand) lead us to believe that in the former case a five membered is formed while in the latter one five membered and the other six membered ring is formed
