Pd Pb Pb Se
PdPb2Se is Indium-like structured and crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one PdPb2Se cluster. Pd(1) is bonded in a distorted L-shaped geometry to one Pb(1) and one Pb(2) atom. The Pd(1)-Pb(1) bond length is 1.27 Å. The Pd(1)-Pb(2) bond length is 1.60 Å. There are two inequivalent Pb sites. In the first Pb site, Pb(1) is bonded in a distorted L-shaped geometry to one Pd(1) and one Se(1) atom. The Pb(1)-Se(1) bond length is 1.60 Å. In the second Pb site, Pb(2) is bonded in a distorted L-shaped geometry to one Pd(1) and one Se(1) atom. The Pb(2)-Se(1) bond length is 1.27 Å. Se(1) is bonded in a distorted L-shaped geometry to one Pb(1) and one Pb(2) atom.
