Abstract

The enthalpies of solution in water of M(NTO)_n·mH₂O (M = metal, NTO = 3-nitro-1,2,4-triazol-5-one; M = Na, n = m = 1; M = La, Ce, Pr, Eu, Sm, n = 3, m = 7; M = Y, Yb, n = 3, m = 6; M = Dy, Tb, n = 3, m = 5; M = Nd, n = 3, m = 8; M = Co, Mn, Mg, n = 2, m = 8) have been measured calorimetrically at 298.15 K. By means of a thermochemical calculation, the standard enthalpies of formation for the above fourteen metal salt hydrates of NTO were obtained. With the help of the above-mentioned data, literature data and Kapustinskii's equation, the lattice energies, lattice enthalpies and standard enthalpies of formation for twenty M(NTO)_n and the lattice energies, lattice enthalpies and standard enthalpies of dehydration were estimated for twenty M(NTO)_n·mH₂O.
