Pt2GeBr is Copper 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 single-bond geometry to one Br(1) atom. The Pt(1)-Br(1) bond length is 1.42 Å. Ge(1) is bonded in a single-bond geometry to one Br(1) atom. The Ge(1)-Br(1) bond length is 1.67 Å. Br(1) is bonded in a distorted trigonal planar geometry to two equivalent Pt(1) and one Ge(1) atom.
