Thermochemical studies of 2,2,6,6-tetramethyl-3,5-heptanedione chelates of scandium group elements

The standard molar enthalpies of formation of crystalline chelates M(thd)3, (M=Sc, Y, La; and thd=2,2,6,6-tetramethyl-3,5-heptanedionate), determined by reaction-solution calorimetry atT=(298.15±0.02) K, were found to be −(2317.83±11.7) kJ · mol−1, −(2386.1±11.4) kJ · mol−1, and −(2442.2±11.8) kJ ·...
