The material described by Y3Ni11Ge4 crystallizes in the hexagonal P6_3/mmc space group. Y(1) is bonded in a 15-coordinate geometry to two equivalent Ni(2), two equivalent Ni(3), six equivalent Ni(1), one Ge(2), and four equivalent Ge(1) atoms. There are three inequivalent Ni sites. In the first Ni site, Ni(1) is bonded in a 12-coordinate geometry to three equivalent Y(1), one Ni(3), two equivalent Ni(2), three equivalent Ni(1), one Ge(2), and two equivalent Ge(1) atoms. In the second Ni site, Ni(2) is bonded in a 12-coordinate geometry to two equivalent Y(1), two equivalent Ni(2), two equivalent Ni(3), four equivalent Ni(1), and two equivalent Ge(1) atoms. In the third Ni site, Ni(3) is bonded in a 12-coordinate geometry to three equivalent Y(1), three equivalent Ni(1), three equivalent Ni(2), and three equivalent Ge(1) atoms. There are two inequivalent Ge sites. In the first Ge site, Ge(2) is bonded in a distorted q6 geometry to three equivalent Y(1) and six equivalent Ni(1) atoms. In the second Ge site, Ge(1) is bonded to four equivalent Y(1), two equivalent Ni(2), two equivalent Ni(3), and four equivalent Ni(1) atoms to form a mixture of distorted corner and face-sharing GeY4Ni8 cuboctahedra. is represented by the Crystallographic Information File (CIF) [CIF]
