FeRe crystallizes in the hexagonal P-6m2 space group. Re(1) is bonded to six equivalent Re(1) and six equivalent Fe(1) atoms to form ReFe6Re6 cuboctahedra that share corners with eighteen equivalent Re(1)Fe6Re6 cuboctahedra, edges with six equivalent Re(1)Fe6Re6 cuboctahedra, edges with twelve equivalent Fe(1)Fe6Re6 cuboctahedra, faces with eight equivalent Re(1)Fe6Re6 cuboctahedra, and faces with twelve equivalent Fe(1)Fe6Re6 cuboctahedra. Fe(1) is bonded to six equivalent Re(1) and six equivalent Fe(1) atoms to form FeFe6Re6 cuboctahedra that share corners with eighteen equivalent Fe(1)Fe6Re6 cuboctahedra, edges with six equivalent Fe(1)Fe6Re6 cuboctahedra, edges with twelve equivalent Re(1)Fe6Re6 cuboctahedra, faces with eight equivalent Fe(1)Fe6Re6 cuboctahedra, and faces with twelve equivalent Re(1)Fe6Re6 cuboctahedra.
