Materials Data on SrNi2Ge by Materials Project

SrNi2Ge crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. Sr is bonded in a 2-coordinate geometry to eight equivalent Ni atoms. There are two shorter (2.99 Å) and six longer (3.29 Å) Sr–Ni bond lengths. Ni is bonded in a 10-coordinate geometry to four equivalent Sr, three equivalent Ni, and three equivalent Ge atoms. All Ni–Ni bond lengths are 2.49 Å. All Ni–Ge bond lengths are 2.41 Å. Ge is bonded in a distorted hexagonal planar geometry to six equivalent Ni atoms.
