Hf Cr Pd Pd
HfCrPd2 crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two HfCrPd2 clusters. Hf(1) is bonded in a single-bond geometry to one Pd(2) atom. The Hf(1)-Pd(2) bond length is 1.01 Å. Cr(1) is bonded in a distorted bent 120 degrees geometry to one Pd(1) and one Pd(2) atom. The Cr(1)-Pd(1) bond length is 1.27 Å. The Cr(1)-Pd(2) bond length is 1.85 Å. There are two inequivalent Pd sites. In the first Pd site, Pd(1) is bonded in a single-bond geometry to one Cr(1) atom. In the second Pd site, Pd(2) is bonded in a distorted single-bond geometry to one Hf(1) and one Cr(1) atom.
