Y Ta Sn Sn
YTaSn2 crystallizes in the triclinic P1 space group. Y(1) is bonded in a 4-coordinate geometry to two equivalent Ta(1), two equivalent Sn(1), and two equivalent Sn(2) atoms. There is one shorter (3.32 Å) and one longer (3.63 Å) Y(1)-Ta(1) bond length. There is one shorter (1.30 Å) and one longer (2.06 Å) Y(1)-Sn(1) bond length. There is one shorter (1.24 Å) and one longer (2.02 Å) Y(1)-Sn(2) bond length. Ta(1) is bonded in a 10-coordinate geometry to two equivalent Y(1), four equivalent Ta(1), two equivalent Sn(1), and two equivalent Sn(2) atoms. There are two shorter (3.24 Å) and two longer (4.09 Å) Ta(1)-Ta(1) bond lengths. There is one shorter (3.47 Å) and one longer (3.82 Å) Ta(1)-Sn(1) bond length. There is one shorter (3.47 Å) and one longer (3.82 Å) Ta(1)-Sn(2) bond length. There are two inequivalent Sn sites. In the first Sn site, Sn(1) is bonded in a 1-coordinate geometry to two equivalent Y(1), two equivalent Ta(1), and one Sn(2) atom. The Sn(1)-Sn(2) bond length is 0.48 Å. In the second Sn site, Sn(2) is bonded in a 3-coordinate geometry to two equivalent Y(1), two equivalent Ta(1), and one Sn(1) atom.
