Tc2MnSi is Cyanogen Chloride-like structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two Tc2MnSi clusters. There are two inequivalent Tc sites. In the first Tc site, Tc(1) is bonded in a single-bond geometry to one Mn(1) atom. The Tc(1)-Mn(1) bond length is 1.11 Å. In the second Tc site, Tc(2) is bonded in a linear geometry to one Mn(1) and one Si(1) atom. The Tc(2)-Mn(1) bond length is 1.11 Å. The Tc(2)-Si(1) bond length is 0.96 Å. Mn(1) is bonded in a linear geometry to one Tc(1) and one Tc(2) atom. Si(1) is bonded in a single-bond geometry to one Tc(2) atom.
