HoH3 crystallizes in the trigonal P-3c1 space group. Ho(1) is bonded in a 11-coordinate geometry to one H(3), two equivalent H(2), and eight equivalent H(1) atoms. There are three inequivalent H sites. In the first H site, H(2) is bonded in a trigonal planar geometry to three equivalent Ho(1) atoms. In the second H site, H(1) is bonded to four equivalent Ho(1) atoms to form a mixture of distorted edge, corner, and face-sharing HHo4 tetrahedra. In the third H site, H(3) is bonded in a trigonal planar geometry to three equivalent Ho(1) atoms.
