TaAg2In crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two TaAg2In clusters. Ta(1) is bonded in a 2-coordinate geometry to two equivalent Ag(1) atoms. Both Ta(1)-Ag(1) bond lengths are 1.12 Å. Ag(1) is bonded in a 1-coordinate geometry to one Ta(1) and one In(1) atom. The Ag(1)-In(1) bond length is 0.50 Å. In(1) is bonded in an L-shaped geometry to two equivalent Ag(1) atoms.
