Sr Sr Te Pb
Sr2PbTe crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one Sr2PbTe cluster. There are two inequivalent Sr sites. In the first Sr site, Sr(1) is bonded in a 2-coordinate geometry to one Pb(1) and one Te(1) atom. The Sr(1)-Pb(1) bond length is 1.57 Å. The Sr(1)-Te(1) bond length is 1.40 Å. In the second Sr site, Sr(2) is bonded in a 2-coordinate geometry to one Pb(1) and one Te(1) atom. The Sr(2)-Pb(1) bond length is 1.40 Å. The Sr(2)-Te(1) bond length is 1.57 Å. Pb(1) is bonded in a 3-coordinate geometry to one Sr(1), one Sr(2), and one Te(1) atom. The Pb(1)-Te(1) bond length is 1.11 Å. Te(1) is bonded in a 3-coordinate geometry to one Sr(1), one Sr(2), and one Pb(1) atom.
