Materials Data on PrTiGe by Materials Project
PrTiGe is Matlockite structured and crystallizes in the tetragonal P4/nmm space group. The structure is three-dimensional. Pr is bonded in a 5-coordinate geometry to five equivalent Ge atoms. There are four shorter (3.10 Å) and one longer (3.45 Å) Pr–Ge bond lengths. Ti is bonded to four equivalent Ge atoms to form a mixture of distorted corner and edge-sharing TiGe4 tetrahedra. All Ti–Ge bond lengths are 2.73 Å. Ge is bonded in a 9-coordinate geometry to five equivalent Pr and four equivalent Ti atoms.
