Materials Data on Ag3Ge5P6 by Materials Project

Ag3Ge5P6 crystallizes in the cubic I-43m space group. The structure is three-dimensional. Ag1+ is bonded in a distorted L-shaped geometry to two equivalent P3- atoms. Both Ag–P bond lengths are 2.55 Å. There are two inequivalent Ge3+ sites. In the first Ge3+ site, Ge3+ is bonded in a distorted T-shaped geometry to three equivalent P3- atoms. All Ge–P bond lengths are 2.48 Å. In the second Ge3+ site, Ge3+ is bonded to four equivalent P3- atoms to form corner-sharing GeP4 tetrahedra. All Ge–P bond lengths are 2.35 Å. P3- is bonded to one Ag1+ and three Ge3+ atoms to form corner-sharing PAgGe3 tetrahedra.
