Materials Data on MoPO5 by Materials Project

Abstract

MoOPO4 crystallizes in the tetragonal P4/n space group. The structure is two-dimensional and consists of one MoOPO4 sheet oriented in the (0, 0, 1) direction. Mo5+ is bonded to five O2- atoms to form distorted MoO5 trigonal bipyramids that share corners with four equivalent PO4 tetrahedra. There is one shorter (1.70 Å) and four longer (2.01 Å) Mo–O bond length. P5+ is bonded to four equivalent O2- atoms to form PO4 tetrahedra that share corners with four equivalent MoO5 trigonal bipyramids. All P–O bond lengths are 1.54 Å. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded in a single-bond geometry to one Mo5+ atom. In the second O2- site, O2- is bonded in a bent 150 degrees geometry to one Mo5+ and one P5+ atom.
