The material structure described by PmAg3 is alpha bismuth trifluoride structured and crystallizes in the cubic Fm-3m space group. Pm(1) is bonded in a distorted body-centered cubic geometry to six equivalent Ag(2) and eight equivalent Ag(1) atoms. There are two inequivalent Ag sites. In the first Ag site, Ag(1) is bonded to four equivalent Pm(1) and four equivalent Ag(2) atoms to form a mixture of distorted edge, face, and corner-sharing AgPm4Ag4 tetrahedra. In the second Ag site, Ag(2) is bonded in a 14-coordinate geometry to six equivalent Pm(1) and eight equivalent Ag(1) atoms. is represented by the CIF file [CIF]
