The structure described by HfRe2 is Hexagonal Laves structured and crystallizes in the hexagonal P6_3/mmc space group. Hf(1) is bonded in a 12-coordinate geometry to three equivalent Re(1) and nine equivalent Re(2) atoms. There are two inequivalent Re sites. In the first Re site, Re(1) is bonded to six equivalent Hf(1) and six equivalent Re(2) atoms to form a mixture of corner, face, and edge-sharing ReHf6Re6 cuboctahedra. In the second Re site, Re(2) is bonded to six equivalent Hf(1), two equivalent Re(1), and four equivalent Re(2) atoms to form a mixture of corner, face, and edge-sharing ReHf6Re6 cuboctahedra. is represented by the Crystallographic Information File (CIF) [CIF]
