All the titration curves are explained well in terms of formation of mononuclear complexes of the type [MnXm(bipy)n](2-m) + (X = CI, Br or SCN), and the formation of [MnCl(bipy)]+, [MnCl2(bipy)], [MnCl(bipy)2]+ and [MnCl2(bipy)2] has been established in the chloride system, [MnBr(bipy)]+, [MnBr2(bipy)], [MnBr(bipy)2]+ in the bromide system, and [Mn(NCS)(bipy)]+, [Mn(NCS)2(bipy)], [Mn(NCS)3(bipy)]-, [Mn(NCS)(bipy)2]+, and [Mn(NCS)2(bipy)2] in the thiocyanate system. The data were analyzed on the basis of the thermodynamic parameters for the binary MnlIbipy and MnII-X (X = Cl, Br and SCN) systems, the latter being determined in previous work. The formation constants, reaction enthalpies, and entropies of the ternary complexes were extracted. The thermodynamic parameters thus obtained are discussed in comparison with those of the corresponding systems of other transition metal(II) ions.
