                      (Sb$_2$O$_3$)x(P$_2$O$_5$)$_{1-x}$ with $x$ = 0.05 and 0.80
                      were measured by neutron and X-ray diffraction with high
                      real-space resolution. The P−O and O−O distance peaks of
                      the PO$_4$ tetrahedra were found with the expected
                      parameters. For the glass of $x$ = 0.80 the Sb−O and O−O
                      coordination numbers and distances suggest highly distorted
                      SbO$_3$ and SbO$_4$ environments according to strong
                      lone-pair effects of the Sb$^{3+}$. The fraction of SbO$_4$
                      has the right portion that all oxygens can form Sb−O−Sb
                      or Sb−O−P bridges. Significant numbers of secondary
                      Sb−O bonds (> 0.25 nm) are extracted. The first
                      diffraction peak at 13 nm$^{−1}$ is related to distances
                      between stacked layers of corner-connected oxygen triangles
                      as in the orthorhombic Sb$_2$O$_3$. For the glass of $x$ =
                      0.05 the medium-range order reminds that of vitreous
                      P$_2$O$_5$. Its SbO$_4$ units are formed with mean Sb−O
                      bonds of 0.210 nm.},
