State of molybdenum clusters in solutions: III. Formation enthalpies of intermediate products of stepwise K2[Мо2(SO4)4] oxidation in 1 M H2SO4 solution

The enthalpies of stepwise oxidation reactions of the ions [Mo-2(SO4)(4)](4-) -> [Mo-2(SO4)(4)](3-) -> [Mo-2(SO4)(4)](2-) -> [DeD3/4(2)(mu-D)(2)O-2(De(2)D)(6)](2-) -> 2(MoO4)(2-), and also the enthalpies of formation of the binuclear molybdenum complexes K-3[Mo-2(SO4)(4)], K-2[Mo-2(SO4)(4)], and [DeD3/4(2)(mu-D)(2)O-2(De(2)D)(6)]SO4 in a 1 De sulfuric acid solution at 298.15 K were determined by the calorimetric titration with continuous titrant input.
