**5.3 Magnetic susceptibility measurement**

The magnetic susceptibility for all the Vanadium complexes at room temperature were recorded by the Gouy's method using Hg[Co(SCN)4] as a calibrant and reported in **Table 4**. The effective magnetic moments were calculated after applying diamagnetic corrections for the ligand components using Pascal's constants. The room temperature μeff values for the vanadium complexes were found in the range 1.71–1.76 B.M. The magnetic susceptibilities of the complexes are consistent with square pyramidal geometry around the central metal ion [27, 28]. The magnetic moments of the compounds investigated are in agreement with the findings of electronic absorption spectra.
