Yb3Cr is alpha bismuth trifluoride structured and crystallizes in the cubic Fm-3m space group. There are two inequivalent Yb sites. In the first Yb site, Yb(1) is bonded to four equivalent Yb(2) and four equivalent Cr(1) atoms to form a mixture of distorted corner, face, and edge-sharing YbYb4Cr4 tetrahedra. In the second Yb site, Yb(2) is bonded in a 14-coordinate geometry to eight equivalent Yb(1) and six equivalent Cr(1) atoms. Cr(1) is bonded in a body-centered cubic geometry to six equivalent Yb(2) and eight equivalent Yb(1) atoms.

In the first Yb site, Yb(1) is bonded to four equivalent Yb(2) and four equivalent Cr(1) atoms to form a mixture of distorted corner, face, and edge-sharing YbYb4Cr4 tetrahedra. All Yb(1)-Yb(2) bond lengths are 3.41 Å. All Yb(1)-Cr(1) bond lengths are 3.41 Å. In the second Yb site, Yb(2) is bonded in a 14-coordinate geometry to eight equivalent Yb(1) and six equivalent Cr(1) atoms. All Yb(2)-Cr(1) bond lengths are 3.94 Å. Cr(1) is bonded in a body-centered cubic geometry to six equivalent Yb(2) and eight equivalent Yb(1) atoms.
