PtGa is alpha carbon monoxide-like structured and crystallizes in the monoclinic C2/m space group. The structure is zero-dimensional and consists of four PtGa clusters. Pt(1) is bonded in a single-bond geometry to one Ga(1) atom. The Pt(1)-Ga(1) bond length is 0.60 Å. Ga(1) is bonded in a single-bond geometry to one Pt(1) atom.
