Sr Hf Nb
SrHfNb crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one SrHfNb cluster. Sr(1) is bonded in a 2-coordinate geometry to one Hf(1) and one Nb(1) atom. The Sr(1)-Hf(1) bond length is 1.45 Å. The Sr(1)-Nb(1) bond length is 0.91 Å. Hf(1) is bonded in a distorted single-bond geometry to one Sr(1) atom. Nb(1) is bonded in a single-bond geometry to one Sr(1) atom.
