Materials Data on KLi2As by Materials Project
KLi2As crystallizes in the orthorhombic Pmmn space group. The structure is three-dimensional. K1+ is bonded to four equivalent As3- atoms to form a mixture of distorted edge and corner-sharing KAs4 tetrahedra. There are two shorter (3.57 Å) and two longer (3.69 Å) K–As bond lengths. Li1+ is bonded in a trigonal planar geometry to three equivalent As3- atoms. There are one shorter (2.62 Å) and two longer (2.63 Å) Li–As bond lengths. As3- is bonded in a 6-coordinate geometry to four equivalent K1+ and six equivalent Li1+ atoms.
