The crystal structure described by DyH3 crystallizes in the trigonal P-3m1 space group. Dy(1) is bonded to two equivalent H(2) and six equivalent H(1) atoms to form a mixture of corner and edge-sharing DyH8 hexagonal bipyramids. There are two inequivalent H sites. In the first H site, H(1) is bonded in a trigonal planar geometry to three equivalent Dy(1) atoms. In the second H site, H(2) is bonded in a linear geometry to two equivalent Dy(1) atoms. is represented by the CIF file [CIF]
