Materials Data on Hf2SiS2 by Materials Project
Hf2SiS2 crystallizes in the tetragonal P4/mmm space group. The structure is zero-dimensional and consists of one Hf2SiS2 cluster. Hf4+ is bonded in a linear geometry to one Si4- and one S2- atom. The Hf–Si bond length is 2.77 Å. The Hf–S bond length is 2.37 Å. Si4- is bonded in a linear geometry to two equivalent Hf4+ atoms. S2- is bonded in a single-bond geometry to one Hf4+ atom.
