NbGeSi crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two NbGeSi clusters. Nb(1) is bonded in a single-bond geometry to one Si(1) atom. The Nb(1)-Si(1) bond length is 0.65 Å. Ge(1) is bonded in a single-bond geometry to one Si(1) atom. The Ge(1)-Si(1) bond length is 1.06 Å. Si(1) is bonded in a linear geometry to one Nb(1) and one Ge(1) atom.
