Abstract

MnCo2O4 is Spinel-like structured and crystallizes in the triclinic P1 space group. The structure is three-dimensional. there are four inequivalent Mn2+ sites. In the first Mn2+ site, Mn2+ is bonded to six O2- atoms to form MnO6 octahedra that share a cornercorner with one MnO4 tetrahedra, corners with five CoO4 tetrahedra, an edgeedge with one MnO6 octahedra, and edges with five CoO6 octahedra. There are a spread of Mn–O bond distances ranging from 1.94–2.20 Å. In the second Mn2+ site, Mn2+ is bonded to four O2- atoms to form MnO4 tetrahedra that share corners with three MnO6 octahedra and corners with nine CoO6 octahedra. The corner-sharing octahedra tilt angles range from 56–64°. There are a spread of Mn–O bond distances ranging from 1.99–2.05 Å.
