The structure described by Th(NiH)2 crystallizes in the hexagonal P6/mmm space group. Th(1) is bonded in a hexagonal planar geometry to six equivalent H(1) atoms. Ni(1) is bonded in a linear geometry to two equivalent H(1) atoms. H(1) is bonded to three equivalent Th(1) and two equivalent Ni(1) atoms to form a mixture of corner and edge-sharing HTh3Ni2 trigonal bipyramids. is represented by the Crystallographic Information File (CIF) [CIF]
