The material structure described by K2NaAlAs2 crystallizes in the orthorhombic Ibam space group. K(1) is bonded in a 4-coordinate geometry to five equivalent As(1) atoms. Na(1) is bonded in a 4-coordinate geometry to four equivalent As(1) atoms. Al(1) is bonded to four equivalent As(1) atoms to form distorted edge-sharing AlAs4 tetrahedra. As(1) is bonded in a 9-coordinate geometry to five equivalent K(1), two equivalent Na(1), and two equivalent Al(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
