The material structure described by AsK is Magnesium tetraboride-like structured and crystallizes in the orthorhombic P2_12_12_1 space group. There are two inequivalent K sites. In the first K site, K(1) is bonded in a 5-coordinate geometry to two equivalent As(2) and three equivalent As(1) atoms. In the second K site, K(2) is bonded in a 6-coordinate geometry to three equivalent As(1) and three equivalent As(2) atoms. There are two inequivalent As sites. In the first As site, As(1) is bonded in a 8-coordinate geometry to three equivalent K(1), three equivalent K(2), and two equivalent As(2) atoms. In the second As site, As(2) is bonded in a 7-coordinate geometry to two equivalent K(1), three equivalent K(2), and two equivalent As(1) atoms. is represented by the CIF file [CIF]
