Materials Data on Th(NiH)2 by Materials Project
Th(NiH)2 crystallizes in the hexagonal P6/mmm space group. The structure is three-dimensional. Th is bonded in a hexagonal planar geometry to six equivalent H atoms. All Th–H bond lengths are 2.50 Å. Ni is bonded in a linear geometry to two equivalent H atoms. Both Ni–H bond lengths are 1.77 Å. H is bonded to three equivalent Th and two equivalent Ni atoms to form a mixture of edge and corner-sharing HTh3Ni2 trigonal bipyramids.
