Hf Mo Se
HfMoSe is Cyanogen Chloride-like structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two HfMoSe clusters. Hf(1) is bonded in a single-bond geometry to one Mo(1) atom. The Hf(1)-Mo(1) bond length is 0.57 Å. Mo(1) is bonded in a linear geometry to one Hf(1) and one Se(1) atom. The Mo(1)-Se(1) bond length is 0.20 Å. Se(1) is bonded in a single-bond geometry to one Mo(1) atom.
