The structure described by LuHSe crystallizes in the hexagonal P-6m2 space group. Lu(1) is bonded in a distorted trigonal planar geometry to three equivalent H(1) and six equivalent Se(1) atoms. H(1) is bonded in a trigonal planar geometry to three equivalent Lu(1) atoms. Se(1) is bonded to six equivalent Lu(1) atoms to form a mixture of distorted corner, face, and edge-sharing SeLu6 pentagonal pyramids. is represented by the CIF file [CIF]
