Abstract: This paper reports the formation thermodynamic properties of the vapor complex REAl3Cl12(RE= La—Lu except for Pm)investigated by quenching experiments in roughly the same temperature and pressure range( 604~851 Kand 0.02~0.20 MPa).The results of the investigation would be the first complete set of property values for vapor rare earth complexes.The relationship between ΔrH0298 and ΔrS0298 and the atomic numbers of the rare earth elements shows that the values of ΔrH0298 and ΔrS0298 decrease from La to Eu and then increase from Eu to Gd,and decrease from Gd to Er and then increase from Er to Lu, indicating a significant Gd break and two weak minimum points at Eu and Er. Here the Gd break is consistent with 1/2-filled 4f shell.
