Ru2Zr is Hexagonal Laves structured and crystallizes in the hexagonal P6_3/mmc space group. Zr(1) is bonded in a 12-coordinate geometry to three equivalent Ru(2) and nine equivalent Ru(1) atoms. There are two inequivalent Ru sites. In the first Ru site, Ru(2) is bonded to six equivalent Zr(1) and six equivalent Ru(1) atoms to form a mixture of corner, edge, and face-sharing RuZr6Ru6 cuboctahedra. In the second Ru site, Ru(1) is bonded to six equivalent Zr(1), two equivalent Ru(2), and four equivalent Ru(1) atoms to form a mixture of corner, edge, and face-sharing RuZr6Ru6 cuboctahedra.
Ru2Zr is Hexagonal Laves structured and crystallizes in the hexagonal P6_3/mmc space group. Zr(1) is bonded in a 12-coordinate geometry to three equivalent Ru(2) and nine equivalent Ru(1) atoms. All Zr(1)-Ru(2) bond lengths are 3.03 Å. There are six shorter (3.01 Å) and three longer (3.08 Å) Zr(1)-Ru(1) bond lengths. There are two inequivalent Ru sites. In the first Ru site, Ru(2) is bonded to six equivalent Zr(1) and six equivalent Ru(1) atoms to form a mixture of corner, edge, and face-sharing RuZr6Ru6 cuboctahedra. All Ru(2)-Ru(1) bond lengths are 2.64 Å. In the second Ru site, Ru(1) is bonded to six equivalent Zr(1), two equivalent Ru(2), and four equivalent Ru(1) atoms to form a mixture of corner, edge, and face-sharing RuZr6Ru6 cuboctahedra. There are two shorter (2.49 Å) and two longer (2.65 Å) Ru(1)-Ru(1) bond lengths.
