Materials Data on K2GeAs2 by Materials Project
Abstract
K2GeAs2 crystallizes in the orthorhombic Ibam space group. The structure is three-dimensional. K1+ is bonded in a 6-coordinate geometry to six equivalent As3- atoms. There are a spread of K–As bond distances ranging from 3.44–3.62 Å. Ge4+ is bonded to four equivalent As3- atoms to form distorted edge-sharing GeAs4 tetrahedra. All Ge–As bond lengths are 2.49 Å. As3- is bonded in a 8-coordinate geometry to six equivalent K1+ and two equivalent Ge4+ atoms.
