Abstract

Mn7(PO8)2 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. there are four inequivalent Mn+3.14+ sites. In the first Mn+3.14+ site, Mn+3.14+ is bonded to six O2- atoms to form distorted MnO6 octahedra that share corners with two equivalent PO4 tetrahedra, corners with four equivalent MnO5 trigonal bipyramids, and edges with two equivalent MnO5 trigonal bipyramids. There are a spread of Mn–O bond distances ranging from 1.89–2.48 Å. In the second Mn+3.14+ site, Mn+3.14+ is bonded to five O2- atoms to form MnO5 trigonal bipyramids that share corners with two equivalent MnO6 octahedra, a cornercorner with one PO4 tetrahedra, corners with two equivalent MnO5 trigonal bipyramids, an edgeedge with one MnO6 octahedra, and an edgeedge with one MnO5 trigonal bipyramid. The corner-sharing octahedra tilt angles range from 44–73°. There are a spread of Mn–O bond distances ranging from 2.06–2.13 Å. In the third Mn+3.14+ site, Mn+3.14+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of Mn–O bond distances ranging from 1.81–2.54 Å. In the fourth Mn+3.14+ site, Mn+3.14+ is bonded to five O2- atoms to form distorted MnO5 trigonal bipyramids that share corners with two equivalent PO4 tetrahedra and corners with twomore »« less
