Sc Co Co Tc
ScTcCo2 crystallizes in the monoclinic Cm space group. Sc(1) is bonded in a 1-coordinate geometry to one Tc(1), one Co(2), and three equivalent Co(1) atoms. The Sc(1)-Tc(1) bond length is 3.03 Å. The Sc(1)-Co(2) bond length is 1.56 Å. There is one shorter (2.15 Å) and two longer (2.53 Å) Sc(1)-Co(1) bond lengths. Tc(1) is bonded in a 11-coordinate geometry to one Sc(1), four equivalent Tc(1), three equivalent Co(1), and three equivalent Co(2) atoms. All Tc(1)-Tc(1) bond lengths are 2.76 Å. There is one shorter (2.98 Å) and two longer (3.27 Å) Tc(1)-Co(1) bond lengths. There is one shorter (2.98 Å) and two longer (3.27 Å) Tc(1)-Co(2) bond lengths. There are two inequivalent Co sites. In the first Co site, Co(1) is bonded in a 4-coordinate geometry to three equivalent Sc(1), three equivalent Tc(1), and one Co(2) atom. The Co(1)-Co(2) bond length is 2.00 Å. In the second Co site, Co(2) is bonded in a 1-coordinate geometry to one Sc(1), three equivalent Tc(1), and one Co(1) atom.
