AsK is Modderite structured and crystallizes in the orthorhombic Pbcm space group. K(1) is bonded to six equivalent As(1) atoms to form a mixture of face, corner, and edge-sharing KAs6 octahedra. The corner-sharing octahedral tilt angles range from 39-56°. As(1) is bonded to six equivalent K(1) atoms to form a mixture of distorted corner and edge-sharing AsK6 pentagonal pyramids.
