| Abstract: | The metal complexes have been Synthesised by allowing Ni-salts to catalyze the Condensation of 3-hydroxy-2-naphthaldehyde with semicarbazide hydrochloride in methanol. Electronic spectral analyses give valuable information about the geometry of complexes and hence its application is essentially needed The electronic absorption spectra of the Ni (II) complexes have been recorded in the range 200 nm to 845 nm. In this range only ligand absorption arising C = O group could be observed but except in few cases, no d-d band could be located due to high ligand absorption and expected low intensity of six coordinated Nickel (II) complexes. The complex in the present case exhibits two bands in the region 14000-19000 cm-1 and a third band near 24000 cm-1. This spectral feature supports nearly octahedral environment of the donor atoms around the central metal ion. |
