The structure described by CeNiSnH2 crystallizes in the hexagonal P6_3/mmc space group. Ce(1) is bonded in a distorted hexagonal planar geometry to six equivalent H(1) atoms. Ni(1) is bonded in a linear geometry to three equivalent Sn(1) and two equivalent H(1) atoms. Sn(1) is bonded in a distorted trigonal planar geometry to three equivalent Ni(1) atoms. H(1) is bonded in a 4-coordinate geometry to three equivalent Ce(1) and one Ni(1) atom. is represented by the CIF file [CIF]
