TcBi2P crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one TcBi2P cluster. Tc(1) is bonded in a 3-coordinate geometry to one Bi(1), one Bi(2), and one P(1) atom. The Tc(1)-Bi(1) bond length is 1.05 Å. The Tc(1)-Bi(2) bond length is 1.15 Å. The Tc(1)-P(1) bond length is 1.54 Å. There are two inequivalent Bi sites. In the first Bi site, Bi(1) is bonded in a distorted L-shaped geometry to one Tc(1) and one Bi(2) atom. The Bi(1)-Bi(2) bond length is 0.57 Å. In the second Bi site, Bi(2) is bonded in a single-bond geometry to one Tc(1) and one Bi(1) atom. P(1) is bonded in a single-bond geometry to one Tc(1) atom.
