Abstract

HoMn2O4 is Spinel structured and crystallizes in the monoclinic C2/m space group. The structure is three-dimensional. Ho3+ is bonded to four O2- atoms to form HoO4 tetrahedra that share corners with twelve MnO6 octahedra. The corner-sharing octahedra tilt angles range from 55–63°. There are two shorter (2.14 Å) and two longer (2.15 Å) Ho–O bond lengths. There are three inequivalent Mn+2.50+ sites. In the first Mn+2.50+ site, Mn+2.50+ is bonded to six O2- atoms to form MnO6 octahedra that share corners with six equivalent HoO4 tetrahedra and edges with six MnO6 octahedra. There are four shorter (1.97 Å) and two longer (2.41 Å) Mn–O bond lengths. In the second Mn+2.50+ site, Mn+2.50+ is bonded to six O2- atoms to form MnO6 octahedra that share corners with six equivalent HoO4 tetrahedra and edges with six MnO6 octahedra. There are four shorter (2.20 Å) and two longer (2.23 Å) Mn–O bond lengths. In the third Mn+2.50+ site, Mn+2.50+ is bonded to six O2- atoms to form MnO6 octahedra that share corners with six equivalent HoO4 tetrahedra and edges with six MnO6 octahedra. There are four shorter (2.08 Å) and two longer (2.32 Å) Mn–O bond lengths. There are three inequivalent O2- sites.more »« less
