TcSiRuSi crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one RuSi cluster and one TcSi cluster. In the RuSi cluster, Ru(1) is bonded in a single-bond geometry to one Si(2) atom. The Ru(1)-Si(2) bond length is 0.58 Å. Si(2) is bonded in a single-bond geometry to one Ru(1) atom. In the TcSi cluster, Tc(1) is bonded in a distorted single-bond geometry to one Si(1) atom. The Tc(1)-Si(1) bond length is 1.12 Å. Si(1) is bonded in a 1-coordinate geometry to one Tc(1) atom.
