Materials Data on EuAgSb by Materials Project

EuAgSb crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. Eu2+ is bonded to six equivalent Sb3- atoms to form a mixture of corner, edge, and face-sharing EuSb6 octahedra. The corner-sharing octahedral tilt angles are 47°. All Eu–Sb bond lengths are 3.46 Å. Ag1+ is bonded in a trigonal planar geometry to three equivalent Sb3- atoms. All Ag–Sb bond lengths are 2.77 Å. Sb3- is bonded in a 9-coordinate geometry to six equivalent Eu2+ and three equivalent Ag1+ atoms.
