Nb Bi Pt Pt
NbPt2Bi crystallizes in the triclinic P1 space group. Nb(1) is bonded in a single-bond geometry to two equivalent Pt(2) and one Bi(1) atom. There is one shorter (2.66 Å) and one longer (2.67 Å) Nb(1)-Pt(2) bond length. The Nb(1)-Bi(1) bond length is 0.38 Å. There are two inequivalent Pt sites. In the first Pt site, Pt(1) is bonded in a 9-coordinate geometry to one Pt(2), four equivalent Pt(1), and four equivalent Bi(1) atoms. The Pt(1)-Pt(2) bond length is 3.39 Å. There are two shorter (3.01 Å) and two longer (3.30 Å) Pt(1)-Pt(1) bond lengths. There are a spread of Pt(1)-Bi(1) bond distances ranging from 2.94-3.46 Å. In the second Pt site, Pt(2) is bonded in a 2-coordinate geometry to two equivalent Nb(1) and one Pt(1) atom. Bi(1) is bonded in a single-bond geometry to one Nb(1) and four equivalent Pt(1) atoms.
