Abstract: The influences of secondary ligand and organic solvent on the mixed ligand comple-xes in the systems of "Titanium(Ⅳ)-5-Br-PADAP-Sulphate", "Titanium(Ⅳ)-5-Br-PADAP-Pyrocatechol" and "Titanium(Ⅳ)-5-Br-PADAP--Hydroxylaminc-Chloroacet-ate" were reported.The composition ratio among their constituents in the three systemsare l:1:2, 1:3:2 and 1: 1: 1: 1, respectively. It was shown by the electropheresis and ion-exchange, that these complexes were all electrified and the first one was a complex anion and the latter two Were ion-pairs formed by associa,tion between thecomplex cation and anion. The concentration ranges in which they obeyed to Beer's law were also reported.
