Hf2Se3 was synthesized and its structure determined using the Rietveld method with X-ray powder diffraction data (Ti5S8 type, space group: P63mc, α = 3.7165(1) Å, χ = 12.4304(2) Å, Z = 2 for Hf1.35Se2, Rp = 0.0600, wRp = 0.0811). The Se atoms form a closed packed array of the h.c. type, the Hf atoms occupy octahedral interstices in alternating fully and 35% occupied layers.
