Na Be Tc Tc
NaBeTc2 crystallizes in the triclinic P1 space group. Na(1) is bonded in a 8-coordinate geometry to four equivalent Na(1), two equivalent Tc(1), and two equivalent Tc(2) atoms. All Na(1)-Na(1) bond lengths are 2.59 Å. There is one shorter (2.95 Å) and one longer (3.19 Å) Na(1)-Tc(1) bond length. There is one shorter (2.95 Å) and one longer (3.19 Å) Na(1)-Tc(2) bond length. Be(1) is bonded in a 4-coordinate geometry to two equivalent Tc(1) and two equivalent Tc(2) atoms. There is one shorter (1.91 Å) and one longer (2.26 Å) Be(1)-Tc(1) bond length. There is one shorter (2.07 Å) and one longer (2.40 Å) Be(1)-Tc(2) bond length. There are two inequivalent Tc sites. In the first Tc site, Tc(1) is bonded in a 1-coordinate geometry to two equivalent Na(1) and two equivalent Be(1) atoms. In the second Tc site, Tc(2) is bonded in a 1-coordinate geometry to two equivalent Na(1) and two equivalent Be(1) atoms.
