Ag5PSeO4 crystallizes in the tetragonal P4/nmm space group. There are two inequivalent Ag sites. In the first Ag site, Ag(1) is bonded in a 3-coordinate geometry to two equivalent Se(1) and two equivalent O(1) atoms. In the second Ag site, Ag(2) is bonded in a 4-coordinate geometry to four equivalent O(1) atoms. P(1) is bonded in a tetrahedral geometry to four equivalent O(1) atoms. Se(1) is bonded in a distorted body-centered cubic geometry to eight equivalent Ag(1) atoms. O(1) is bonded to one Ag(2), two equivalent Ag(1), and one P(1) atom to form a mixture of distorted corner and edge-sharing OAg3P tetrahedra.
Ag5PSeO4 crystallizes in the tetragonal P4/nmm space group. There are two inequivalent Ag sites. In the first Ag site, Ag(1) is bonded in a 3-coordinate geometry to two equivalent Se(1) and two equivalent O(1) atoms. There is one shorter (2.60 Å) and one longer (3.13 Å) Ag(1)-Se(1) bond length. Both Ag(1)-O(1) bond lengths are 2.38 Å. In the second Ag site, Ag(2) is bonded in a 4-coordinate geometry to four equivalent O(1) atoms. All Ag(2)-O(1) bond lengths are 2.48 Å. P(1) is bonded in a tetrahedral geometry to four equivalent O(1) atoms. All P(1)-O(1) bond lengths are 1.57 Å. Se(1) is bonded in a distorted body-centered cubic geometry to eight equivalent Ag(1) atoms. O(1) is bonded to one Ag(2), two equivalent Ag(1), and one P(1) atom to form a mixture of distorted corner and edge-sharing OAg3P tetrahedra.
