KMnAs is Matlockite structured and crystallizes in the tetragonal P4/nmm space group. K(1) is bonded in a 9-coordinate geometry to four equivalent Mn(1) and five equivalent As(1) atoms. Mn(1) is bonded to four equivalent K(1) and four equivalent As(1) atoms to form a mixture of distorted face and edge-sharing MnK4As4 tetrahedra. As(1) is bonded in a 9-coordinate geometry to five equivalent K(1) and four equivalent Mn(1) atoms.
KMnAs is Matlockite structured and crystallizes in the tetragonal P4/nmm space group. K(1) is bonded in a 9-coordinate geometry to four equivalent Mn(1) and five equivalent As(1) atoms.
