The material structure described by HfBe2 is hexagonal omega structure structured and crystallizes in the hexagonal P6/mmm space group. Be(1) is bonded in a 9-coordinate geometry to three equivalent Be(1) and six equivalent Hf(1) atoms. Hf(1) is bonded to twelve equivalent Be(1) atoms to form a mixture of face and edge-sharing HfBe12 cuboctahedra. is represented by the CIF file [CIF]
