Mg Si Pd
MgPdSi crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two MgPdSi clusters. Mg(1) is bonded in a linear geometry to one Pd(1) and one Si(1) atom. The Mg(1)-Pd(1) bond length is 0.99 Å. The Mg(1)-Si(1) bond length is 1.43 Å. Pd(1) is bonded in a single-bond geometry to one Mg(1) atom. Si(1) is bonded in a single-bond geometry to one Mg(1) atom.
