 Title    The Influence of Different Solvents on the Interaction between Metal Ions and Tetracycline  
 Abstract    The interaction o f the antibiotic tetracycline with a few metal ions, esp. Cu(II), in different so l­ vents has been investigated by means o f IR, ESR, and U V /V IS spectroscopy. It could be shown that the site o f com plexation depends on the solvent used. In DM SO the interaction occurs mainly via the A ring. In water (pH = 5.7) and octanol, the A chrom ophore as well as the BCD entity o f the m olecule are involved in com plexation. If the tetracycline concentration exceeds the Cu(II) concentration, a 2 : 1 (antibiotic : Cu(II)) com plex seems to be formed, at least in DM SO.
