The material described by Cr2AgBiO8 crystallizes in the tetragonal I-4 space group. There are two inequivalent Cr sites. In the first Cr site, Cr(1) is bonded in a tetrahedral geometry to four equivalent O(1) atoms. In the second Cr site, Cr(2) is bonded in a tetrahedral geometry to four equivalent O(2) atoms. Ag(1) is bonded in a 8-coordinate geometry to four equivalent O(1) and four equivalent O(2) atoms. Bi(1) is bonded in a 8-coordinate geometry to four equivalent O(1) and four equivalent O(2) atoms. There are two inequivalent O sites. In the first O site, O(1) is bonded in a distorted single-bond geometry to one Cr(1), one Ag(1), and one Bi(1) atom. In the second O site, O(2) is bonded in a distorted single-bond geometry to one Cr(2), one Ag(1), and one Bi(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
