NdH3 crystallizes in the trigonal P-3c1 space group. Nd(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 Nd(1) atoms. In the second H site, H(3) is bonded in a trigonal planar geometry to three equivalent Nd(1) atoms. In the third H site, H(1) is bonded to four equivalent Nd(1) atoms to form a mixture of distorted corner, face, and edge-sharing HNd4 tetrahedra.
