Materials Data on CaNiGe by Materials Project
CaNiGe is Matlockite structured and crystallizes in the tetragonal P4/nmm space group. The structure is three-dimensional. Ca is bonded in a 9-coordinate geometry to four equivalent Ni and five equivalent Ge atoms. All Ca–Ni bond lengths are 3.00 Å. There are four shorter (3.10 Å) and one longer (3.25 Å) Ca–Ge bond lengths. Ni is bonded in a 8-coordinate geometry to four equivalent Ca and four equivalent Ge atoms. All Ni–Ge bond lengths are 2.44 Å. Ge is bonded in a 9-coordinate geometry to five equivalent Ca and four equivalent Ni atoms.
