Cr Cr Co Tc
Cr2TcCo is alpha Po structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two Cr2TcCo clusters. Cr(1) is bonded in a 3-coordinate geometry to one Cr(1), one Tc(1), and one Co(1) atom. The Cr(1)-Cr(1) bond length is 0.92 Å. The Cr(1)-Tc(1) bond length is 0.93 Å. The Cr(1)-Co(1) bond length is 0.93 Å. Tc(1) is bonded in a 3-coordinate geometry to two equivalent Cr(1) and one Co(1) atom. The Tc(1)-Co(1) bond length is 0.92 Å. Co(1) is bonded in a 3-coordinate geometry to two equivalent Cr(1) and one Tc(1) atom.
