We first investigated the difference in local order between ReaxFF and ab initio glasses by examining the metal-ligand bonds (Zn-N), central to the Zn(Im) 4 tetrahedral structure represented on Figure . For the two models, we plot and compare the partial radial distribution functions (RDF) g(r) for the Zn-N atom pairs on Figure and for Zn-Zn pairs on Figure .
