Materials Data on GeAsAu by Materials Project

AuGeAs crystallizes in the monoclinic C2 space group. The structure is three-dimensional. Au1- is bonded in a rectangular see-saw-like geometry to two equivalent Ge4+ and two equivalent As3- atoms. There are one shorter (2.51 Å) and one longer (2.53 Å) Au–Ge bond lengths. Both Au–As bond lengths are 2.56 Å. Ge4+ is bonded in a trigonal non-coplanar geometry to two equivalent Au1- and one As3- atom. The Ge–As bond length is 2.50 Å. As3- is bonded to two equivalent Au1-, one Ge4+, and one As3- atom to form distorted corner-sharing AsGeAsAu2 tetrahedra. The As–As bond length is 2.49 Å.
