| 摘 要： | [Sm(C7H5O3)2(C4H6NO2S)]·2H2O was synthesized from the reaction of samarium chloride hexahydrate with salicylic acid and thioproline,and characterized by IR,elemental analysis and thermogravimatric analysis.The standard molar enthalpies of the solutions of SmCl3·6H2O(s),2[C7H6O3(s)],[C4H7NO2S(s)] and [Sm(C7H5O3)2·(C4H6NO2S)·2H2O(s)] in a mixed solvent of absolute ethyl alcohol,dimethyl formamide(DMF) and 3 mol/L HCl were,respectively,determined by calorimetry to be Δs Θ [SmCl3·6H2O(s),298.15 K]=(-46.68±0.15)...
