DyHSe crystallizes in the hexagonal P-6m2 space group. Dy(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 Dy(1) atoms. Se(1) is bonded to six equivalent Dy(1) atoms to form a mixture of distorted edge, corner, and face-sharing SeDy6 pentagonal pyramids.
