CuMnAs is Matlockite structured and crystallizes in the tetragonal P4/nmm space group. Mn(1) is bonded in a 9-coordinate geometry to four equivalent Cu(1) and five equivalent As(1) atoms. Cu(1) is bonded to four equivalent Mn(1), four equivalent Cu(1), and four equivalent As(1) atoms to form a mixture of corner and face-sharing CuMn4Cu4As4 cuboctahedra. As(1) is bonded in a 9-coordinate geometry to five equivalent Mn(1) and four equivalent Cu(1) atoms.
