Metal Complexes of Salical-N-α -Alanino Hydroxamic Acid (Schiff Base)

Department of Chemistry, Jadavpur University, Calcutta.-700 032 Manuscript received 4 July 1978, revised 12 December 1982, accepted 9 March 1984 Schiff base, salical-N-\(\propto\)-alaninohydroxamic acid, (RH2), has been prepared and its complexes with Ni(II), Cu(II), Co(II), Mn(ll), Cr(III) and. UO2(II) have been isolated in the solid state. All the products are found insoluble in water or common organic solvents. The general formula for the complexes is [M(R) H2O)] except for the Cr(lll) complex [Cr(R)(NO3)(H2O)]. H2O and the UO2(ll) complex, [UO2(RH)2]- Attempts have been made to characterise the complexes with the help of the magnetic moment values, reflectance visible spectra, ir spectra and thermogravimetric analysis
