K Sr Sr Te
KSr2Te crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two KSr2Te clusters. K(1) is bonded in a single-bond geometry to one Sr(1), one Sr(2), and one Te(1) atom. The K(1)-Sr(1) bond length is 0.99 Å. The K(1)-Sr(2) bond length is 2.47 Å. The K(1)-Te(1) bond length is 4.04 Å. There are two inequivalent Sr sites. In the first Sr site, Sr(1) is bonded in a single-bond geometry to one K(1) and one Sr(2) atom. The Sr(1)-Sr(2) bond length is 2.17 Å. In the second Sr site, Sr(2) is bonded in a 2-coordinate geometry to one K(1) and one Sr(1) atom. Te(1) is bonded in a single-bond geometry to one K(1) atom.
