The crystal structure described by MnGeAs2 is Chalcopyrite structured and crystallizes in the tetragonal I-42d space group. Mn(1) is bonded to four equivalent As(1) atoms to form MnAs4 tetrahedra that share corners with four equivalent Mn(1)As4 tetrahedra and corners with eight equivalent Ge(1)As4 tetrahedra. Ge(1) is bonded to four equivalent As(1) atoms to form GeAs4 tetrahedra that share corners with four equivalent Ge(1)As4 tetrahedra and corners with eight equivalent Mn(1)As4 tetrahedra. As(1) is bonded to two equivalent Mn(1) and two equivalent Ge(1) atoms to form corner-sharing AsMn2Ge2 tetrahedra. is represented by the Crystallographic Information File (CIF) [CIF]
