HfAgBi2 crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two HfAgBi2 clusters. Hf(1) is bonded in a 2-coordinate geometry to two equivalent Bi(1) atoms. Both Hf(1)-Bi(1) bond lengths are 2.06 Å. Ag(1) is bonded in a 2-coordinate geometry to two equivalent Bi(1) atoms. Both Ag(1)-Bi(1) bond lengths are 2.06 Å. Bi(1) is bonded in a 2-coordinate geometry to one Hf(1) and one Ag(1) atom.
