THE CO-ORDINATIVE POWER OF URANYL. PART IV. THE HEATS OF SOLVATION OF THE BIS (DIBENZOYLMETHANATO) URANYL COMPLEX
Calorimetric measurements of heats of formation of certain solvate s of the bis(dibenzoylmethanato)uranyl complex are reported. The heats of solvation were calculated from the measured heats of solution in pyridine of the anhydrous complexes, solvated complexes, and solvate molecules respectively. The heat of reaction between the bis(dibenzoylmethanato)uranyl complex and one molecule of water is 14.48 kcal/mole/sup -1/. The results support the hypothesis that even in the bis-( BETA -diketonato)uranyl monohydrate water is attached directly by a U--0 bond. The heat of addition of 2.5 molecules of water is 32.38 kcal/ mole/ sup -1/, which is 2.2 times the heat of addition for only one molecule, indicating that at least two of the water molecules are co-ordinated directly to the uranium.
