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 C80Ⅱ calorimeter. The standard molar enthalpy of dissolution was determined to be Δ_dissH^θ_m=－43.607 kJ·mol^－1. The empirical formulae for calculating the enthalpies of dissolution (Δ_dissH=－43.607－454.98b+9378.2b^1/2) of the title coordination complex at different concentrations b (mol·kg^－1) was obtained. Relative apparent molar enthalpy (ΦL_i), relative partial molar enthalpy (L_i) and enthalpy of dilution (Δ_dilH_{1, 2}) were obtained respectively from the experimental data of the enthalpies of dissolution of the coordination compound: ΦL_i =－454.98b+9378.2b^1/2, L_i=－909.96b+14067.3b^1/2 and Δ_dilH_{1, 2}=－454.98(b^1/2_２－b^1/2_１)+9378.2(b₂-b₁).
