| Abstract: | Extracts with tri-n-octylammonium chloro complexes of Cu(II), Zn(II) and Co(II) of various compositions, including the N-deuterated compounds, were prepared and investigated by IR spectroscopy and conductivity measurements. Besides the well-known 2:1-complexes (TOAH+)2MCl42?, for which new assignments of νNH frequencies are given, complexes with a stoichiometric ratio TOA:M > 2 were found. Their cations contain the groups (TOAH …Cl…HTOA)+ and TOAH+ and they are supposed to be 3:1-complexes (TOAH…Cl…HTOA)+TOAH+MCl42?. The IR spectrum of the 1:1-complex TOAH+CuCl3? is given. The occurrence of the analogous 1:1-complex TOAH+ZnCl3? could not be detected under the preparative conditions used. |
