WSiPdSi crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two tungsten silicide (wsi) molecules and two PdSi clusters. In each PdSi cluster, Pd(1) is bonded in a distorted single-bond geometry to one Si(2) atom. The Pd(1)-Si(2) bond length is 0.93 Å. Si(2) is bonded in a distorted single-bond geometry to one Pd(1) atom.
