YZnSn2 is Parent of FeAs superconductors-derived structured and crystallizes in the tetragonal P4/nmm space group. Y(1) is bonded to four equivalent Zn(1), four equivalent Sn(1), and four equivalent Sn(2) atoms to form a mixture of corner, face, and edge-sharing YZn4Sn8 cuboctahedra. Zn(1) is bonded in a 4-coordinate geometry to four equivalent Y(1) and four equivalent Sn(2) atoms. There are two inequivalent Sn sites. In the first Sn site, Sn(1) is bonded in a 8-coordinate geometry to four equivalent Y(1) and four equivalent Sn(1) atoms. In the second Sn site, Sn(2) is bonded in a 8-coordinate geometry to four equivalent Y(1) and four equivalent Zn(1) atoms.
