Ba Ba Te Pt
Ba2PtTe crystallizes in the monoclinic Cm space group. There are two inequivalent Ba sites. In the first Ba site, Ba(1) is bonded in a 2-coordinate geometry to one Pt(1) and four equivalent Te(1) atoms. The Ba(1)-Pt(1) bond length is 2.62 Å. There are a spread of Ba(1)-Te(1) bond distances ranging from 2.97-4.16 Å. In the second Ba site, Ba(2) is bonded in a 6-coordinate geometry to four equivalent Pt(1) and two equivalent Te(1) atoms. There are a spread of Ba(2)-Pt(1) bond distances ranging from 2.79-4.03 Å. There is one shorter (3.04 Å) and one longer (3.84 Å) Ba(2)-Te(1) bond length. Pt(1) is bonded in a 5-coordinate geometry to one Ba(1) and four equivalent Ba(2) atoms. Te(1) is bonded in a 6-coordinate geometry to two equivalent Ba(2) and four equivalent Ba(1) atoms.
