Materials Data on Y(VSn)6 by Materials Project
YV6Sn6 crystallizes in the hexagonal P6/mmm space group. The structure is three-dimensional. Y is bonded to eight Sn atoms to form edge-sharing YSn8 hexagonal bipyramids. There are two shorter (3.06 Å) and six longer (3.19 Å) Y–Sn bond lengths. V is bonded in a 12-coordinate geometry to six Sn atoms. There are a spread of V–Sn bond distances ranging from 2.80–2.86 Å. There are three inequivalent Sn sites. In the first Sn site, Sn is bonded in a 8-coordinate geometry to one Y, six equivalent V, and one Sn atom. The Sn–Sn bond length is 3.11 Å. In the second Sn site, Sn is bonded in a 6-coordinate geometry to six equivalent V atoms. In the third Sn site, Sn is bonded in a 12-coordinate geometry to three equivalent Y and six equivalent V atoms.
