AgAlB2 crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one AgAlB2 cluster. Ag(1) is bonded in a linear geometry to one B(1) and one B(2) atom. The Ag(1)-B(1) bond length is 0.67 Å. The Ag(1)-B(2) bond length is 0.67 Å. Al(1) is bonded in a single-bond geometry to one B(2) atom. The Al(1)-B(2) bond length is 1.16 Å. There are two inequivalent B sites. In the first B site, B(1) is bonded in a single-bond geometry to one Ag(1) atom. In the second B site, B(2) is bonded in a bent 150 degrees geometry to one Ag(1) and one Al(1) atom.
