MPa) molar enthalpies of formation of some crystalline dialkyldithiocarbamate iron(III), cobalt(III), chromium(III), and manganese(III) complexes were determined at the temperature 298.15 K by solution reaction calorimetry. From these values and estimated values for the standard enthalpies of sublimation of the complexes, the mean molar bond-dissociation enthalpies 〈D〉(M-S) were derived.

Facile Synthesis of Medium‐Entropy Metal Sulfides as High‐Efficiency Electrocatalysts toward Oxygen Evolution Reaction
Developing highly efficient and durable electrocatalysts toward oxygenevolutionreaction (OER) is an urgent demand to produce clean hydrogen energy. In this study, a series of medium-entropy metal sulfides (MEMS) of (NiFeCoX)3S4 (where X = Mn, Cr, Zn) are synthesized by a facile one-pot solvothermal strategy using molecular precursors. Benefiting from the multiple-metal synergistic effect and the
