Materials Data on HfSnO3 by Materials Project
HfSnO3 is Hydrophilite-derived structured and crystallizes in the trigonal R-3 space group. The structure is two-dimensional and consists of three HfSnO3 sheets oriented in the (0, 0, 1) direction. Hf4+ is bonded to six equivalent O2- atoms to form edge-sharing HfO6 octahedra. There are three shorter (2.09 Å) and three longer (2.10 Å) Hf–O bond lengths. Sn2+ is bonded in a distorted T-shaped geometry to three equivalent O2- atoms. All Sn–O bond lengths are 2.20 Å. O2- is bonded in a distorted trigonal planar geometry to two equivalent Hf4+ and one Sn2+ atom.
