NiAgSn2 is Indium-like structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two NiAgSn2 clusters. Ni(1) is bonded in a 3-coordinate geometry to one Ag(1) and two equivalent Sn(1) atoms. The Ni(1)-Ag(1) bond length is 0.80 Å. Both Ni(1)-Sn(1) bond lengths are 0.60 Å. Ag(1) is bonded in a distorted single-bond geometry to one Ni(1) atom. Sn(1) is bonded in a single-bond geometry to one Ni(1) atom.
