Ta Si Pd Pd
PdTaPdSi crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two palladium;silicon molecules and two PdTa clusters. In each PdTa cluster, Ta(1) is bonded in a single-bond geometry to one Pd(2) atom. The Ta(1)-Pd(2) bond length is 1.78 Å. Pd(2) is bonded in a distorted single-bond geometry to one Ta(1) atom.
