| Description | The tridentate dibasic Schiff base anthranilic acid salicylideneimine $(H_{2}$SB) reacts with $VOCl_{2}$ in the presence o f NaOAc and imidazole (or its derivatives) to form dimeric oxovanadium (IV) complexes of the type [VO(S $B)(D)]_{2}$. These green or yellow -green compounds have a magnetic moment of 1.4 B.M . at room temperature, and are non-electrolytes in MeOH . The compounds are characterised on the basis of electronic and IR spectra as well as EPR spectroscopy. The IR spectra shows a strong band due to v(V = O) at 880 $cm^{-1}$ in addition to the bands of $H_{2}$SB and imidazole. $[VO(SB)(Im)]_{2}$ shows a single unresolved EPR signal at g = 1.9715 whereas compounds containing other imidazole derivatives show both a broadening and shifting of the signal. The thermogravimetric measurements indicate the stability of the complexes and their stepwise thermal decomposition. |
