abstract = {The atomic structures of Zn and Na borophosphate glasses
were studied using X-ray and neutron scattering techniques.
Peaks assigned to the B−O, P−O, and O−O distances
confirm that only BO4 units co-exist with the PO4
tetrahedra. The Zn−O and Na−O coordination numbers are
found to be a little larger than four. The narrowest peaks
of the Zn−O first-neighbor distances exist for the glasses
along a line connecting the Zn(PO$_3$)$_2$ and BPO$_4$
compositions (50 mol\% P$_2$O$_5$), which is explained by
networks of ZnO$_4$, BO$_4$, and PO$_4$ tetrahedra with
twofold coordinated oxygens. The calculated amounts of
available oxygen support this interpretation. Broadened
peaks occur for glasses with lower P$_2$O$_5$ contents,
which is consistent with the presence of threefold
coordinated oxygens. The two distinct P−O peak components
of the Zn and Na borophosphate glasses differ in their
relative abundances. This is interpreted as follows: Na$^+$
cations coordinate oxygens in some P−O−B bridges, which
is something not seen for the Zn$< {2+}$ ions.},
