Abstract A novel polydentate phosphorus-containing complexing agent,cis,cis-1,3,5-tri[2-(diphenyl-phosphinyl)ethylamino]cyclohexane, has been prepared on the basis ofcis,cis-1,3,5-triamino-cyclohexane. The method of potentiometric titration in an aqueous—organic medium (70% ethanol, ionic strength 0.01M LiNO3, 298 K) has been used to study the acid-base and complexing properties of the title compound. The ligand thus prepared forms 1∶1 complexes with Cu2+, Co2+, Zn2+, and Ni2+ cations; formation of hydroxocomplexes MOHL+ has been observed in the case of Zn2+ and Cd2+.
