Sr Sr Bi Pt
Sr2PtBi crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two Sr2PtBi clusters. Sr(1) is bonded in an L-shaped geometry to one Pt(1) and one Bi(1) atom. The Sr(1)-Pt(1) bond length is 1.27 Å. The Sr(1)-Bi(1) bond length is 1.27 Å. Pt(1) is bonded in an L-shaped geometry to two equivalent Sr(1) atoms. Bi(1) is bonded in an L-shaped geometry to two equivalent Sr(1) atoms.
