InSi(Ge)2 crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one ge2h6 molecule and one InSi cluster. In the InSi cluster, In(1) is bonded in a single-bond geometry to one Si(1) atom. The In(1)-Si(1) bond length is 0.19 Å. Si(1) is bonded in a single-bond geometry to one In(1) atom.
