Y Y Cr Sn
Y2CrSn crystallizes in the monoclinic Cm space group. Y(1) is bonded in a distorted single-bond geometry to one Cr(1) and three equivalent Sn(1) atoms. The Y(1)-Cr(1) bond length is 1.56 Å. There are a spread of Y(1)-Sn(1) bond distances ranging from 2.91-3.41 Å. Cr(1) is bonded in a distorted water-like geometry to two equivalent Y(1) and two equivalent Sn(1) atoms. There is one shorter (2.47 Å) and one longer (3.09 Å) Cr(1)-Sn(1) bond length. Sn(1) is bonded in a 8-coordinate geometry to six equivalent Y(1) and two equivalent Cr(1) atoms.
