Abstract

Among the molecular constants needed for calculating the thermodynamic properties of yttrium triiodide, onlyR(Y- I) measured in the 1950s by electron diffractometry with a high error are available in the literature [1]. It was assumed that the geometrical configuration of YI3 has D3h symmetry. In [2] it was attempted to estimate the vibration frequencies of yttrium triiodide (the errors are not given and are thought to be more than 15%).

To refine the available data in the framework of our program of molecular constant determination for transition metal iodides, we investigated the structure of yttrium triiodide by gas phase electron diffractometry. This paper deals with the results of this study.
