DyCr2Sn crystallizes in the trigonal R3m space group. Dy(1) is bonded in a 11-coordinate geometry to three equivalent Cr(2), four equivalent Cr(1), and four equivalent Sn(1) atoms. All Dy(1)-Cr(2) bond lengths are 2.71 Å. There are three shorter (2.71 Å) and one longer (3.95 Å) Dy(1)-Cr(1) bond length. There are three shorter (2.72 Å) and one longer (3.56 Å) Dy(1)-Sn(1) bond length. There are two inequivalent Cr sites. In the first Cr site, Cr(1) is bonded in a 3-coordinate geometry to four equivalent Dy(1) atoms. In the second Cr site, Cr(2) is bonded in a single-bond geometry to three equivalent Dy(1) and one Sn(1) atom. The Cr(2)-Sn(1) bond length is 0.39 Å. Sn(1) is bonded in a single-bond geometry to four equivalent Dy(1) and one Cr(2) atom.
