The structure described by HfN2 is Corundum-like structured and crystallizes in the hexagonal P6_3/mmc space group. Hf(1) is bonded in a 6-coordinate geometry to six equivalent N(1) atoms. N(1) is bonded to three equivalent Hf(1) and one N(1) atom to form a mixture of distorted face and corner-sharing NHf3N trigonal pyramids. is represented by the CIF card [CIF]
