YSiAgSi is alpha carbon monoxide-derived structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two AgSi clusters and two YSi clusters. In each AgSi cluster, Ag(1) is bonded in a single-bond geometry to one Si(2) atom. The Ag(1)-Si(2) bond length is 0.51 Å. Si(2) is bonded in a single-bond geometry to one Ag(1) atom. In each YSi cluster, Y(1) is bonded in a single-bond geometry to one Si(1) atom. The Y(1)-Si(1) bond length is 0.16 Å. Si(1) is bonded in a single-bond geometry to one Y(1) atom.
