The crystal structure described by LaNiSnH2 crystallizes in the hexagonal P6_3/mmc space group. La(1) is bonded in a distorted hexagonal planar geometry to six equivalent Sn(1) and 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 six equivalent La(1) and three equivalent Ni(1) atoms. H(1) is bonded to three equivalent La(1) and one Ni(1) atom to form a mixture of distorted corner and edge-sharing HLa3Ni tetrahedra. is represented by the Crystallographic Information File (CIF) [CIF]
