| Abstract: | Six new dinuclear complexes, derived from cis-[Co(H2O)2(NH3)4]3+, cis-[Co(H2O)2(en)2]3+ and [M(CN)42? (M = Ni, Pd, Pt) were prepared and characterized by means of chemical analysis, electronic and IR measurements. The influence of the pH on the rate of the reaction was studied for the two derivatives of [Pd(CN)4]2?, showing that the best conditions to obtain the dinuclear compounds are at pH near 6, where the predominant species are cis-[Co(OH)(H2O)(amine)2]2+. The [Pt(CN)4]2? derivatives show PtPt interactions both in the solid state and in solution. |
