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.

Materials Data on Pr2TiGe2 by Materials Project

Pr2TiGe2 crystallizes in the tetragonal P4/mmm space group. The structure is zero-dimensional and consists of one Pr2TiGe2 cluster. Pr is bonded in a distorted single-bond geometry to one Ge atom. The Pr–Ge bond length is 3.02 Å. Ti is bonded in a linear geometry to two equivalent Ge atoms. Both Ti–Ge bond lengths are 2.53 Å. Ge is bonded in a distorted linear geometry to one Pr and one Ti atom.

Materials Data on PrTiGe3 by Materials Project

PrTiGe3 crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. Pr is bonded in a 12-coordinate geometry to twelve equivalent Ge atoms. There are six shorter (3.17 Å) and six longer (3.32 Å) Pr–Ge bond lengths. Ti is bonded to six equivalent Ge atoms to form face-sharing TiGe6 octahedra. All Ti–Ge bond lengths are 2.61 Å. Ge is bonded in a 8-coordinate geometry to four equivalent Pr, two equivalent Ti, and two equivalent Ge atoms. Both Ge–Ge bond lengths are 2.58 Å.
