The material structure described by LiAs3 is Sodium arsenide structured and crystallizes in the hexagonal P6_3/mmc space group. Li(1) is bonded in a distorted trigonal planar geometry to three equivalent As(2) and eight equivalent As(1) atoms. There are two inequivalent As sites. In the first As site, As(1) is bonded in a 10-coordinate geometry to four equivalent Li(1), three equivalent As(1), and three equivalent As(2) atoms. In the second As site, As(2) is bonded in a trigonal planar geometry to three equivalent Li(1) and six equivalent As(1) atoms. is represented by the CIF file [CIF]
