Description:
<jats:p>The infrared spectra of isatin-3-thiosemicarbazone and its 1-methyl derivative “Marboran” are discussed. By means of i.r. and <jats:sup>1</jats:sup>H-n.m.r. spectra their molecular conformations in solid and dissolved state are established. Complexes of Cu (II), Cu (I), Ni (II) and Zn (II) as well as of Fe (II), and Co (II) were prepared. Their structures follow from spectra and magnetic measurements.</jats:p>
