Abstract
Complexation of the titanium ions upon the anodic (j = 5-50 mA/cm(2)) disso lution of metal in a CO(NH2)(2)-(5-20 mol %) NH4Cl melt at 393-423 K was st udied by spectroscopic methods (electronic, EPR, and IR spectroscopy). The dissolution at a current density of j 5-20 mA/cm(2) gives the octahedral Ti (II) complexes with carbamide coordinated through the oxygen atom, whereas at j = 30-50 mA/cm(2), the quasi-octahedral Ti(III) complexes are formed, w ith the carbamide molecule coordinated through the nitrogen atom.
