Ca In In Tc
CaTcIn2 is Indium-like structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two CaTcIn2 clusters. Ca(1) is bonded in a distorted water-like geometry to one Tc(1) and two equivalent In(1) atoms. The Ca(1)-Tc(1) bond length is 1.55 Å. Both Ca(1)-In(1) bond lengths are 0.95 Å. Tc(1) is bonded in a single-bond geometry to one Ca(1) atom. In(1) is bonded in a single-bond geometry to one Ca(1) atom.
