Hf Cr Ag Ag
AgHfAg(Cr) is alpha carbon monoxide-derived structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two Ag(Cr) clusters and two AgHf clusters. In each Ag(Cr) cluster, Cr(1) is bonded in a single-bond geometry to one Ag(1) atom. The Cr(1)-Ag(1) bond length is 0.73 Å. Ag(1) is bonded in a single-bond geometry to one Cr(1) atom. In each AgHf cluster, Hf(1) is bonded in a single-bond geometry to one Ag(2) atom. The Hf(1)-Ag(2) bond length is 1.27 Å. Ag(2) is bonded in a single-bond geometry to one Hf(1) atom.
