Materials Data on ErTiGe by Materials Project
ErTiGe is Matlockite structured and crystallizes in the tetragonal P4/nmm space group. The structure is three-dimensional. Er is bonded in a 5-coordinate geometry to five equivalent Ge atoms. There are four shorter (2.95 Å) and one longer (3.12 Å) Er–Ge bond lengths. Ti is bonded to four equivalent Ge atoms to form a mixture of distorted corner and edge-sharing TiGe4 cuboctahedra. All Ti–Ge bond lengths are 2.76 Å. Ge is bonded in a 9-coordinate geometry to five equivalent Er and four equivalent Ti atoms.
