Zr Zr Tc Bi
Zr2TcBi is alpha Po structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two Zr2TcBi clusters. Zr(1) is bonded in an L-shaped geometry to one Tc(1) and one Bi(1) atom. The Zr(1)-Tc(1) bond length is 1.06 Å. The Zr(1)-Bi(1) bond length is 1.06 Å. Tc(1) is bonded in a distorted L-shaped geometry to two equivalent Zr(1) atoms. Bi(1) is bonded in a distorted L-shaped geometry to two equivalent Zr(1) atoms.
