Y Y Ta Ge
Y2TaGe crystallizes in the triclinic P1 space group. There are two inequivalent Y sites. In the first Y site, Y(1) is bonded in a 2-coordinate geometry to two equivalent Y(2) and two equivalent Ge(1) atoms. There is one shorter (2.33 Å) and one longer (3.16 Å) Y(1)-Y(2) bond length. There is one shorter (2.43 Å) and one longer (2.76 Å) Y(1)-Ge(1) bond length. In the second Y site, Y(2) is bonded in a 8-coordinate geometry to two equivalent Y(1), two equivalent Y(2), two equivalent Ta(1), and two equivalent Ge(1) atoms. Both Y(2)-Y(2) bond lengths are 3.17 Å. There is one shorter (2.43 Å) and one longer (2.76 Å) Y(2)-Ta(1) bond length. There is one shorter (2.96 Å) and one longer (3.24 Å) Y(2)-Ge(1) bond length. Ta(1) is bonded in a distorted single-bond geometry to two equivalent Y(2) and one Ge(1) atom. The Ta(1)-Ge(1) bond length is 1.37 Å. Ge(1) is bonded in a 1-coordinate geometry to two equivalent Y(1), two equivalent Y(2), and one Ta(1) atom.
