TaCrPd2 is Ammonia-derived structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two TaCrPd2 clusters. Ta(1) is bonded in a distorted trigonal planar geometry to one Cr(1) and two equivalent Pd(1) atoms. The Ta(1)-Cr(1) bond length is 0.19 Å. Both Ta(1)-Pd(1) bond lengths are 0.31 Å. Cr(1) is bonded in a single-bond geometry to one Ta(1) atom. Pd(1) is bonded in a single-bond geometry to one Ta(1) atom.
