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.
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. All Li(1)-As(2) bond lengths are 2.43 Å. There are six shorter (2.99 Å) and two longer (3.13 Å) Li(1)-As(1) bond lengths. 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. All As(1)-As(1) bond lengths are 2.80 Å. All As(1)-As(2) bond lengths are 2.99 Å. 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.
