Cr Cr Si Tc
Cr2TcSi is Cyanogen Chloride-like structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two Cr2TcSi clusters. There are two inequivalent Cr sites. In the first Cr site, Cr(1) is bonded in a single-bond geometry to one Si(1) atom. The Cr(1)-Si(1) bond length is 0.09 Å. In the second Cr site, Cr(2) is bonded in a single-bond geometry to one Tc(1) atom. The Cr(2)-Tc(1) bond length is 1.02 Å. Tc(1) is bonded in a linear geometry to one Cr(2) and one Si(1) atom. The Tc(1)-Si(1) bond length is 0.13 Å. Si(1) is bonded in a linear geometry to one Cr(1) and one Tc(1) atom.
