Cr2PdSi is Cyanogen Chloride-like structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two Cr2PdSi clusters. There are two inequivalent Cr sites. In the first Cr site, Cr(1) is bonded in a distorted linear geometry to one Pd(1) and one Si(1) atom. The Cr(1)-Pd(1) bond length is 1.91 Å. The Cr(1)-Si(1) bond length is 1.14 Å. In the second Cr site, Cr(2) is bonded in a single-bond geometry to one Pd(1) atom. The Cr(2)-Pd(1) bond length is 1.91 Å. Pd(1) is bonded in a linear geometry to one Cr(1) and one Cr(2) atom. Si(1) is bonded in a single-bond geometry to one Cr(1) atom.
