The Hydrous Enthalpy of NTO

Based on the literature data of the enthalpies of solution in water,ΔsolHθm,lattice enthalpy,ΔHθL,lattice energy,ΔUθL for the complexes of the lanthanidi metals with 3-nitro-1,2,4-triazol-5-one(NTO),M(NTO)n·mH2O(M=La,Ce,Pr,Eu,Sm,Gd,n=3,m=7;M=Y,Yb,n=3,m=6;M=Dy,Tb,n=3,m=5;M=Nd,n=3,m=8),standard enthalpies of formation,ΔfHθm(Mn+,aq,∞),ΔfHθm(Mn+,g),ΔfHθm(H2O,g),ΔfHθm(H2O,l),ΔfHθm(NTO-,aq,∞),ΔfHθm(NTO-,g) and hydrous enthalpy of Mn+,ΔhHθm(Mn+),the hydrous enthalpy of NTO-,ΔhHθm(NTO-) was estimated as-(153.73±0.21) kJ·mol-1.
