The metal complexes have been Synthesised by allowing Co-salts to Condense 3-hydroxy-2-naphthaldehyde with semicarbazide hydrochloride in methanolic solution. The spin orbital coupling vibrational interactions and distortion form cubic symmetry have important effects on the spectra of Co(II) Complexes. The complexes mainly display charge-transfer bands and intraligand transitions in the region 470-200 nm. In a few cases, the complexes display weak band or shoulder near 510-520 nm In the electonic spectra of the complexes.

Co-salts, 3-hydroxy-2-naphthaldehyde, octahedral, semicarbazide, squareplanar, tetrahedral.
