In eq. (27), Affg is the Born hydration enthalpy, n is the difference in the total number of moles between the gaseous and solution species and AH, is the enthalpy of vaporization of water. According to these calculations, the hydration stabilizes the TCTP strueture of La(H2 0)g+ by 15 kJ mol relative to the square antiprism structure of La(H20)g . By contrast, [Lu(H2 0)g] is stabilized in the square antiprism structure by 1 kJ mol relative to [Lu(H20)g] in the TCTP structure. The difference between the hydration free energies [A(AGg)] of the octahydrate and... [Pg.426]

ESR spectra of many a metal-carbon bonded complexes have been investigated (Table 4.8). Numerous four-coordinate MR4-type complexes have symmetry lower than tetrahedral, for example, [Cr(CH2SiMe3)4] , [V(CH2SiMe3)4], [Cr(CH2SiMe3)4], etc. The compound ReMe has a structure of a distorted octahedron because of the Jahn-Teller effect. In contrast to ReF, the distortion of ReMeg is not dynamic. This situation may be due to a considerably larger lODq value for the methyl complex compared to the fluoro derivative. Based on ESR spectra, a square-antiprism structure was proposed for [ReMcg] . [Pg.215]
