Y Mg Tc Tc
MgYTc2 crystallizes in the triclinic P1 space group. Mg(1) is bonded in a distorted single-bond geometry to one Tc(1) and one Tc(2) atom. The Mg(1)-Tc(1) bond length is 2.03 Å. The Mg(1)-Tc(2) bond length is 1.07 Å. Y(1) is bonded in a 10-coordinate geometry to six equivalent Y(1), two equivalent Tc(1), and two equivalent Tc(2) atoms. There are four shorter (2.88 Å) and two longer (3.36 Å) Y(1)-Y(1) bond lengths. There is one shorter (3.51 Å) and one longer (3.92 Å) Y(1)-Tc(1) bond length. There is one shorter (3.51 Å) and one longer (3.92 Å) Y(1)-Tc(2) bond length. There are two inequivalent Tc sites. In the first Tc site, Tc(1) is bonded in a distorted single-bond geometry to one Mg(1) and two equivalent Y(1) atoms. In the second Tc site, Tc(2) is bonded in a distorted single-bond geometry to one Mg(1) and two equivalent Y(1) atoms.
