Na Na Te Pt
Na2PtTe crystallizes in the triclinic P1 space group. There are two inequivalent Na sites. In the first Na site, Na(1) is bonded in a single-bond geometry to two equivalent Pt(1) and one Te(1) atom. There is one shorter (2.74 Å) and one longer (3.28 Å) Na(1)-Pt(1) bond length. The Na(1)-Te(1) bond length is 0.96 Å. In the second Na site, Na(2) is bonded in a single-bond geometry to two equivalent Pt(1) and one Te(1) atom. There is one shorter (3.12 Å) and one longer (3.37 Å) Na(2)-Pt(1) bond length. The Na(2)-Te(1) bond length is 0.47 Å. Pt(1) is bonded in a 6-coordinate geometry to two equivalent Na(1), two equivalent Na(2), and two equivalent Pt(1) atoms. Both Pt(1)-Pt(1) bond lengths are 3.24 Å. Te(1) is bonded in a distorted bent 150 degrees geometry to one Na(1) and one Na(2) atom.
