Pt2GeBr is alpha Po structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two Pt2GeBr clusters. Pt(1) is bonded in a 2-coordinate geometry to one Ge(1) and one Br(1) atom. The Pt(1)-Ge(1) bond length is 1.19 Å. The Pt(1)-Br(1) bond length is 1.19 Å. Ge(1) is bonded in a 3-coordinate geometry to two equivalent Pt(1) and one Br(1) atom. The Ge(1)-Br(1) bond length is 1.33 Å. Br(1) is bonded in a 3-coordinate geometry to two equivalent Pt(1) and one Ge(1) atom.
