Abstract
The molar enthalpies of dissolution of [Mn(SCZ)3] (PA)2 · H2O in N, N-dimethylformamide (DMF) at 298.15 K were measured by means of a SETARAM C80 n calorimeter. The standard molar enthalpy of dissolution was determined to be ΔdissHmθ = -43.607 kJ · mol-1. The empirical formulae for calculating the enthalpies of dissolution (ΔdissH = -43.607 - 454.986 + 9378.2b1/2) of the title coordination complex at different concentrations b (mol · kg-1) was obtained. Relative apparent molar enthalpy (ΦLi), relative partial molar enthalpy (Li) and enthalpy of dilution (ΔdilH1,2) were obtained respectively from the experimental data of the enthalpies of dissolution of the coordination compound: ΦLi = -454.986 + 9378.2b1/2, Li = -909.96b + 14067.3b1/2 and ΔdilH1,2 = -454.98(b21/2 - b11/2) + 9378.2(b2 - b1).
