K Si Si Tc
KTcSi2 crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one KTcSi2 cluster. K(1) is bonded in a single-bond geometry to one Tc(1) and one Si(2) atom. The K(1)-Tc(1) bond length is 2.35 Å. The K(1)-Si(2) bond length is 0.27 Å. Tc(1) is bonded in a bent 120 degrees geometry to one K(1) and one Si(1) atom. The Tc(1)-Si(1) bond length is 1.28 Å. There are two inequivalent Si sites. In the first Si site, Si(1) is bonded in a single-bond geometry to one Tc(1) atom. In the second Si site, Si(2) is bonded in a single-bond geometry to one K(1) atom.
