Abstract

We report the complexes of the deprotonated cycloserine (ccs) ligand, 4-aminoisoxazolidin-3-one, with the metal ions chromium(III), manganese(II), iron(II), iron(III), cobalt(II), nicke1(II), zinc(II), zirconium(IV), palladium(II), silver(I), cadmium(II), osmium(III), platinum(II) and mercury(II). The tentative structures of the complexes have been assigned on the basis of analytical, spectral(u.v.- visible, i.r. and far i.r.) and magnetic data, and of thermal analyses (t.g. and d.t.g.). These complexes appear to contain ccs as an uninegative bidentate ligand forming five-membered rings in which the O- and the NH2 groups bind to the metals. The ligand field parameters have been evaluated and are in keeping with the proposed structures; they confirm the presence of oxygen-and nitrogen-containing chromophores.
