Ion Pair Association Of Complexes Of La3+ And Nd3+ With Br- And No3 - In N,n-dimethylacetamide
Polyhedron. , v. 1, n. 1, p. 49 - 51, 1982.
The formation constants and the respective variations of enthalpy were obtained by means of calorimetric titration of the lanthanides La3+ and Nd3+ with bromide and nitrate in N,N-dimethylacetamide. These thermochemical data were calculated for the 1:1 and 1:2 species which are less stable than the corresponding species obtained with chloride. The order of stability Cl- > Br->NO3 - was established for both species of La3+, and the order Br->Cl->LNO3 - for 1:1 species of Nd3+. NdCl2 + and NdBr2 + species were not detected. Our results support the view that the metal-anion interactions involve inner sphere species. © 1982.114951Lagowski, (1967) The Chemistry of Non-Aqueous Solvents, 11. , Academic Press, LondonGutmann, (1968) Coordination Chemistry in Non-Aqueous Solutions, , Springer, New YorkSimoni, Airoldi, Chagas, Thermochemistry of dichlorobis(NN-dimethylacetamide)-zinc(II), and dichloro(NN-dimethylacetamide)-cadmium(II) and -mercury(II) (1980) Journal of the Chemical Society, Dalton Transactions, p. 156Mayer, Ionic equilibria in donor solvents (1975) Pure and Applied Chemistry, 41, p. 291Mayer, (1976) Coord.
