Materials Data on HfIN by Materials Project

HfNI crystallizes in the trigonal R-3m space group. The structure is two-dimensional and consists of three HfNI sheets oriented in the (0, 0, 1) direction. Hf4+ is bonded in a 4-coordinate geometry to four equivalent N3- and three equivalent I1- atoms. There are one shorter (2.13 Å) and three longer (2.18 Å) Hf–N bond lengths. All Hf–I bond lengths are 3.07 Å. N3- is bonded to four equivalent Hf4+ atoms to form a mixture of distorted corner and edge-sharing NHf4 trigonal pyramids. I1- is bonded in a 12-coordinate geometry to three equivalent Hf4+ atoms.
