Materials Data on Nd2Mo4O15 by Materials Project
Nd2Mo4O15 crystallizes in the triclinic P-1 space group. The structure is three-dimensional. there are two inequivalent Nd3+ sites. In the first Nd3+ site, Nd3+ is bonded to seven O2- atoms to form distorted NdO7 pentagonal bipyramids that share corners with six MoO4 tetrahedra. There are a spread of Nd–O bond distances ranging from 2.35–2.56 Å. In the second Nd3+ site, Nd3+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of Nd–O bond distances ranging from 2.40–2.79 Å. There are four inequivalent Mo6+ sites. In the first Mo6+ site, Mo6+ is bonded to four O2- atoms to form MoO4 tetrahedra that share a cornercorner with one NdO7 pentagonal bipyramid. There are a spread of Mo–O bond distances ranging from 1.76–1.85 Å. In the second Mo6+ site, Mo6+ is bonded to four O2- atoms to form MoO4 tetrahedra that share corners with three equivalent NdO7 pentagonal bipyramids. There are a spread of Mo–O bond distances ranging from 1.78–1.85 Å. In the third Mo6+ site, Mo6+ is bonded to four O2- atoms to form MoO4 tetrahedra that share corners with two equivalent NdO7 pentagonal bipyramids. There are a spread of Mo–O bond distances ranging from 1.78–1.84 Å. In the fourth Mo6+ site, Mo6+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of Mo–O bond distances ranging from 1.72–2.40 Å. There are fifteen inequivalent O2- sites.
