Y Fe Te Te
YFeTe2 crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two YFeTe2 clusters. Y(1) is bonded in an L-shaped geometry to one Te(1) and one Te(2) atom. The Y(1)-Te(1) bond length is 1.24 Å. The Y(1)-Te(2) bond length is 1.24 Å. Fe(1) is bonded in a distorted single-bond geometry to one Te(1) atom. The Fe(1)-Te(1) bond length is 2.23 Å. There are two inequivalent Te sites. In the first Te site, Te(1) is bonded in a distorted single-bond geometry to one Y(1) and one Fe(1) atom. In the second Te site, Te(2) is bonded in a single-bond geometry to one Y(1) atom.
