Standard Enthalpies of Formation of Rare Earth L-Proline Chloride Complexes ”RE(L-Pro)2(H2O)5”Cl3 (RE=Ho, Er)
Two crystalline compounds of rare-earth chlorides coordinated with L-proline,”RE(L-Pro)2(H2O)5”Cl3 (RE =Ho, Er), were synthesized.Their were characterized: ”RE(LPro)2(H2O)5”Cl3 (RE =Ho, Er) to be 98.85 % and 98.62 %, respectively.After the measurement of the dissolving heat of the two systems, at 298.15 K, △fHmθ””Ho(LPro)2(H2O)5”Cl3, s, 298.15 K” =-3675.0 ± 1.3 kJ·mol-1, AfHmθ””Er(L-Pro)2(H2O)5”Cl3, s,298.15 K” =-3655.9 ± 1.6 kJ·mol-1, respectively.
