The crystal structure described by PrNiSnH crystallizes in the orthorhombic Pnma space group. Pr(1) is bonded in a 3-coordinate geometry to six equivalent Sn(1) and three equivalent H(1) atoms. Ni(1) is bonded in a single-bond geometry to four equivalent Sn(1) and one H(1) atom. Sn(1) is bonded in a 10-coordinate geometry to six equivalent Pr(1) and four equivalent Ni(1) atoms. H(1) is bonded to three equivalent Pr(1) and one Ni(1) atom to form a mixture of corner and edge-sharing HPr3Ni tetrahedra. is represented by the Crystallographic Information File (CIF) [CIF]
