The structure described by VMnAs is Matlockite structured and crystallizes in the tetragonal P4/nmm space group. V(1) is bonded to four equivalent V(1), four equivalent Mn(1), and four equivalent As(1) atoms to form distorted VMn4V4As4 cuboctahedra that share corners with four equivalent V(1)Mn4V4As4 cuboctahedra, corners with four equivalent Mn(1)V4As5 square pyramids, edges with eight equivalent Mn(1)V4As5 square pyramids, faces with eight equivalent V(1)Mn4V4As4 cuboctahedra, and faces with four equivalent Mn(1)V4As5 square pyramids. Mn(1) is bonded to four equivalent V(1) and five equivalent As(1) atoms to form distorted MnV4As5 square pyramids that share corners with four equivalent V(1)Mn4V4As4 cuboctahedra, corners with four equivalent Mn(1)V4As5 square pyramids, edges with eight equivalent V(1)Mn4V4As4 cuboctahedra, edges with eight equivalent Mn(1)V4As5 square pyramids, faces with four equivalent V(1)Mn4V4As4 cuboctahedra, and faces with four equivalent Mn(1)V4As5 square pyramids. As(1) is bonded in a 9-coordinate geometry to four equivalent V(1) and five equivalent Mn(1) atoms. is represented by the CIF file [CIF]
