Table 1.
Average coordination numbers (CNs) of Mg, Zn, Ca, and Sr atoms in Mg66Zn30Ca4 and Mg66Zn30Ca3Sr1. The values in the parentheses are the average distances of the nearest neighbor atoms. The first and the second atoms in each pair type are the reference atom and the nearest neighbor atom, respectively.
