Ta Ta P Pd
PdTaTaP crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two tantalum phosphide molecules and two PdTa clusters. In each PdTa cluster, Ta(2) is bonded in a 1-coordinate geometry to one Pd(1) atom. The Ta(2)-Pd(1) bond length is 1.56 Å. Pd(1) is bonded in a distorted single-bond geometry to one Ta(2) atom.
