KCrKTc crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one KCr cluster and one KTc cluster. In the KCr cluster, K(1) is bonded in a distorted single-bond geometry to one Cr(1) atom. The K(1)-Cr(1) bond length is 0.59 Å. Cr(1) is bonded in a distorted single-bond geometry to one K(1) atom. In the KTc cluster, K(2) is bonded in a single-bond geometry to one Tc(1) atom. The K(2)-Tc(1) bond length is 0.59 Å. Tc(1) is bonded in a distorted single-bond geometry to one K(2) atom.
