Title: Materials Data on Y4(Mo2O7)3 by Materials Project

Abstract

Y4(Mo2O7)3 crystallizes in the monoclinic C2/m space group. The structure is three-dimensional. there are four inequivalent Y3+ sites. In the first Y3+ site, Y3+ is bonded to eight O2- atoms to form distorted YO8 hexagonal bipyramids that share edges with four YO8 hexagonal bipyramids and edges with six MoO6 octahedra.
