- 中文摘要: The solubility property of the ternary of Cr(NO3)3-Met-H2O has been investigated in the whole concentration by the phase equilibrium method, and the phase diagram has been constructed. From the phase diagram, the congruently soluble complexes Cr(Met)(NO3)3·2H2O (D) and Cr(Met)2(NO3)3·2H2O (E) have been prepared and characterized by chemical analysis, elemental analysis, IR and TG-DTG. Their combustion energies have been determined by a RBC-type I precision rotating-bomb calorimeter , and their standard enthalpies of formation, Df, Hqm, have been calculated as (-1842.01 ± 2.13) kJ·mol-1 and (-1136.16 ± 4.45) kJ·mol-1, respectively.
