The crystal structure described by Hf3SnO8 is Hydrophilite-derived structured and crystallizes in the monoclinic P2 space group. There are three inequivalent Hf sites. In the first Hf site, Hf(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form distorted HfO6 octahedra that share corners with four equivalent Hf(2)O6 octahedra, corners with four equivalent Hf(3)O6 octahedra, and edges with two equivalent Sn(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 52-54°. In the second Hf site, Hf(2) is bonded to two equivalent O(1), two equivalent O(3), and two equivalent O(4) atoms to form HfO6 octahedra that share corners with four equivalent Hf(1)O6 octahedra, corners with four equivalent Sn(1)O6 octahedra, and edges with two equivalent Hf(3)O6 octahedra. The corner-sharing octahedral tilt angles range from 52-55°. In the third Hf site, Hf(3) is bonded to two equivalent O(2), two equivalent O(3), and two equivalent O(4) atoms to form HfO6 octahedra that share corners with four equivalent Hf(1)O6 octahedra, corners with four equivalent Sn(1)O6 octahedra, and edges with two equivalent Hf(2)O6 octahedra. The corner-sharing octahedral tilt angles range from 52-54°. Sn(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(4) atoms to form SnO6 octahedra that share corners with four equivalent Hf(2)O6 octahedra, corners with four equivalent Hf(3)O6 octahedra, and edges with two equivalent Hf(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 52-55°. There are four inequivalent O sites. In the first O site, O(1) is bonded in a trigonal planar geometry to one Hf(1), one Hf(2), and one Sn(1) atom. In the second O site, O(2) is bonded in a trigonal planar geometry to one Hf(1), one Hf(3), and one Sn(1) atom. In the third O site, O(3) is bonded in a trigonal planar geometry to one Hf(1), one Hf(2), and one Hf(3) atom. In the fourth O site, O(4) is bonded in a trigonal planar geometry to one Hf(2), one Hf(3), and one Sn(1) atom. is represented by the CIF file [CIF]
