Materials Data on NaHfScO4 by Materials Project
Abstract
NaScHfO4 crystallizes in the orthorhombic Pmc2_1 space group. The structure is three-dimensional. there are two inequivalent Na1+ sites. In the first Na1+ site, Na1+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of Na–O bond distances ranging from 2.53–2.76 Å. In the second Na1+ site, Na1+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of Na–O bond distances ranging from 2.52–2.76 Å. There are two inequivalent Sc3+ sites. In the first Sc3+ site, Sc3+ is bonded to six O2- atoms to form ScO6 octahedra that share corners with four equivalent HfO6 octahedra, edges with two equivalent ScO6 octahedra, and edges with two equivalent HfO6 octahedra. The corner-sharing octahedra tilt angles range from 50–56°. There are a spread of Sc–O bond distances ranging from 2.13–2.15 Å. In the second Sc3+ site, Sc3+ is bonded to six O2- atoms to form ScO6 octahedra that share corners with four equivalent HfO6 octahedra, edges with two equivalent ScO6 octahedra, and edges with two equivalent HfO6 octahedra. The corner-sharing octahedra tilt angles range from 49–57°. There are a spread of Sc–O bond distances ranging from 2.12–2.16 Å. There are two inequivalent Hf4+ sites.more »
