SiGe is Wurtzite structured and crystallizes in the hexagonal P6_3mc space group. Ge(1) is bonded to four equivalent Si(1) atoms to form corner-sharing GeSi4 tetrahedra. Si(1) is bonded to four equivalent Ge(1) atoms to form corner-sharing SiGe4 tetrahedra.
SiGe is Wurtzite structured and crystallizes in the hexagonal P6_3mc space group. Ge(1) is bonded to four equivalent Si(1) atoms to form corner-sharing GeSi4 tetrahedra. There are three shorter (2.40 Å) and one longer (2.41 Å) Ge(1)-Si(1) bond length. Si(1) is bonded to four equivalent Ge(1) atoms to form corner-sharing SiGe4 tetrahedra.
