YbNd3 is Magnesium-derived structured and crystallizes in the hexagonal P6_3/mmc space group. Yb(1) is bonded to twelve Nd(1,1) atoms to form YbNd12 cuboctahedra that share corners with six equivalent Yb(1)Nd12 cuboctahedra; corners with twelve Nd(1,1)Yb4Nd8 cuboctahedra; edges with eighteen Nd(1,1)Yb4Nd8 cuboctahedra; faces with eight equivalent Yb(1)Nd12 cuboctahedra; and faces with twelve Nd(1,1)Yb4Nd8 cuboctahedra. There are two inequivalent Nd sites. In the first Nd site, Nd(1) is bonded to four equivalent Yb(1) and eight Nd(1,1) atoms to form NdYb4Nd8 cuboctahedra that share corners with four equivalent Yb(1)Nd12 cuboctahedra; corners with fourteen equivalent Nd(1)Yb4Nd8 cuboctahedra; edges with six equivalent Yb(1)Nd12 cuboctahedra; edges with twelve Nd(1,1)Yb4Nd8 cuboctahedra; faces with four equivalent Yb(1)Nd12 cuboctahedra; and faces with sixteen Nd(1,1)Yb4Nd8 cuboctahedra. In the second Nd site, Nd(1) is bonded to four equivalent Yb(1) and eight equivalent Nd(1) atoms to form NdYb4Nd8 cuboctahedra that share corners with four equivalent Yb(1)Nd12 cuboctahedra; corners with fourteen Nd(1,1)Yb4Nd8 cuboctahedra; edges with six equivalent Yb(1)Nd12 cuboctahedra; edges with twelve equivalent Nd(1)Yb4Nd8 cuboctahedra; faces with four equivalent Yb(1)Nd12 cuboctahedra; and faces with sixteen Nd(1,1)Yb4Nd8 cuboctahedra.

There are six shorter (3.69 Å) and six longer (3.71 Å) Yb(1)-Nd(1,1) bond lengths. There are two inequivalent Nd sites. In the first Nd site, Nd(1) is bonded to four equivalent Yb(1) and eight Nd(1,1) atoms to form NdYb4Nd8 cuboctahedra that share corners with four equivalent Yb(1)Nd12 cuboctahedra; corners with fourteen equivalent Nd(1)Yb4Nd8 cuboctahedra; edges with six equivalent Yb(1)Nd12 cuboctahedra; edges with twelve Nd(1,1)Yb4Nd8 cuboctahedra; faces with four equivalent Yb(1)Nd12 cuboctahedra; and faces with sixteen Nd(1,1)Yb4Nd8 cuboctahedra. There are a spread of Nd(1)-Nd(1,1) bond distances ranging from 3.65-3.76 Å. In the second Nd site, Nd(1) is bonded to four equivalent Yb(1) and eight equivalent Nd(1) atoms to form NdYb4Nd8 cuboctahedra that share corners with four equivalent Yb(1)Nd12 cuboctahedra; corners with fourteen Nd(1,1)Yb4Nd8 cuboctahedra; edges with six equivalent Yb(1)Nd12 cuboctahedra; edges with twelve equivalent Nd(1)Yb4Nd8 cuboctahedra; faces with four equivalent Yb(1)Nd12 cuboctahedra; and faces with sixteen Nd(1,1)Yb4Nd8 cuboctahedra.
