Materials Data on K2CuAs by Materials Project
K2CuAs crystallizes in the orthorhombic Cmcm space group. The structure is three-dimensional. K1+ is bonded in a 4-coordinate geometry to four equivalent As3- atoms. There are a spread of K–As bond distances ranging from 3.42–3.54 Å. Cu1+ is bonded in a linear geometry to two equivalent As3- atoms. Both Cu–As bond lengths are 2.36 Å. As3- is bonded in a 10-coordinate geometry to eight equivalent K1+ and two equivalent Cu1+ atoms.
