Sr Hf Tc Tc
SrTcHfTc is Cubic alpha N2-derived structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two HfTc clusters and two SrTc clusters. In each HfTc cluster, Hf(1) is bonded in a distorted single-bond geometry to one Tc(1) atom. The Hf(1)-Tc(1) bond length is 1.25 Å. Tc(1) is bonded in a single-bond geometry to one Hf(1) atom. In each SrTc cluster, Sr(1) is bonded in a single-bond geometry to one Tc(2) atom. The Sr(1)-Tc(2) bond length is 0.58 Å. Tc(2) is bonded in a single-bond geometry to one Sr(1) atom.
