Abstract
Reaction of copper perchlorate hexahydrate [Cu(H 2O)](OClO4) with NaaiR´ in Acetone medium following ligand addition leads to [Cu(N3)2(NaaiR/)2] and [Cu2(--N3)2(NaaiR/)2], NaaiR/ = naphthyl-azo imidazole /benzimidazole /pyridine = C10H4-N=N- / C3H2-NN-1-R/, (R imidazole) / C7H4-NN-1-H (Benzimidazole), / C3H4-N-(Pyridine), abbreviated as N,N/-chelator, where N(imidazole) and N(azo) represent N and N/, respectively; R/ = H(a), Me (b), N3 = monodentate azide linkage, --N3 = azide bridged binuclear complex ]. The 1H NMR spectral measurements suggest the molecular structure of bis chelated complex with the protons at the aromatic region and naphthyl protons at higher ∂ value. The voltammogramalso shows a small anodic peak at 0.2 V, possibly due to the Cu (I)/Cu (0) couple.
