Title: Materials Data on Na2MoO4 by Materials Project

Abstract

Na2MoO4 crystallizes in the orthorhombic Ama2 space group. The structure is three-dimensional. there are two inequivalent Na1+ sites. In the first Na1+ site, Na1+ is bonded in a distorted square co-planar geometry to four O2- atoms. There are a spread of Na–O bond distances ranging from 2.32–2.57 Å. In the second Na1+ site, Na1+ is bonded to six O2- atoms to form distorted NaO6 octahedra that share corners with six equivalent MoO4 tetrahedra and edges with two equivalent NaO6 octahedra. There are a spread of Na–O bond distances ranging from 2.40–2.62 Å. Mo6+ is bonded to four O2- atoms to form MoO4 tetrahedra that share corners with six equivalent NaO6 octahedra. The corner-sharing octahedra tilt angles range from 45–50°. There is two shorter (1.79 Å) and two longer (1.81 Å) Mo–O bond length. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a 3-coordinate geometry to two Na1+ and one Mo6+ atom. In the second O2- site, O2- is bonded to three Na1+ and one Mo6+ atom to form a mixture of distorted edge and corner-sharing ONa3Mo trigonal pyramids. In the third O2- site, O2- is bonded to three Na1+ and one Mo6+ atommore » to form a mixture of distorted edge and corner-sharing ONa3Mo tetrahedra.« less
