Materials Data on YGe2 by Materials Project

YGe2 crystallizes in the tetragonal I4_1/amd space group. The structure is three-dimensional. Y is bonded to twelve equivalent Ge atoms to form a mixture of distorted edge and face-sharing YGe12 cuboctahedra. There are eight shorter (3.11 Å) and four longer (3.49 Å) Y–Ge bond lengths. Ge is bonded in a 9-coordinate geometry to six equivalent Y and three equivalent Ge atoms. There are two shorter (2.54 Å) and one longer (2.60 Å) Ge–Ge bond lengths.
