Investigation of highly reduced halides of cerium, praseodymium, and neodymium

Creators

Description

Results of studies of the light lanthanide chlorides, Ce, Pr, and Ne are presented and discussed. It was found that to form a monohalide in these systems the following conditions are required: (1) no stable +2 state; (2) at least 2 outer electrons (or a very low promotion energy to a state with 2 electrons); (3) a low value of rare earth sublimation energy. The stability of CsReCl3 is dependent on the following: strong metal-metal interactions; or a highly stable +2 state (large value of negative rare earth sublimation energy and positive rare earth ionization energy)
