Abstract: Two sets of new compartmental azo-linked Schiff base ligands set-1 and set-2 have been derived from N, N'-Bis-(2-amino-ethyl)-ethane-1,2-diamine and 1-(5-Chloro-2-hydroxy-phenyl)-ethanone (H4L), propane 1,3-diamine and 1-(5-Chloro-2-hydroxy-phenyl)-ethanone (H2L) by 1:2 molar ratio in dry methanol solvent medium respectively and the synthesized compartmental ligands are employed for the preparation of complex(1) [Ni(H2L)], complex (2) [VO(L2)(N3)] using Ni(NO)3.6H2O only & VO(acac)2 in presence of NaN3. In complex (1) compartmental Schiff base (H4L) function as hexadentate character through N,O chelating donor but for complex (2) (H2L) totally display tetradentate nature via imine nitrogen only. Both Schiff bases and complexes were characterized by elemental (C, H & N), mass (m/e), molar conductivity, IR, UV-Vis, 1H NMR spectroscopic study. Molar conductivity study strongly support that both complexes are non electrolyte in nature. Additional magnetic moment data will be provided to guess the expected probable structure of complex (1) & complex (2). Electronic spectra and magnetic moment study have been established that the expected geometrical environment of Ni(II),VO(V) complexes (1) & (2) are octahedral, square pyramidal respectively. The complex (1) showed magnetic moment value within the range of µ=2.7-2.9.BM. Complex (2) magnetic moment data strongly support the environment of vanadium is square pyramidal.
