description: MnZnO2 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 five O2- atoms to form distorted MnO5 trigonal bipyramids that share corners with four MnO5 trigonal bipyramids, corners with four ZnO5 trigonal bipyramids, an edgeedge with one ZnO5 trigonal bipyramid, and edges with two equivalent MnO5 trigonal bipyramids. There are a spread of Mn–O bond distances ranging from 2.05–2.32 Å. In the second Mn2+ site, Mn2+ is bonded to five O2- atoms to form distorted MnO5 trigonal bipyramids that share corners with two equivalent ZnO5 trigonal bipyramids, corners with four MnO5 trigonal bipyramids, edges with two equivalent MnO5 trigonal bipyramids, and a faceface with one ZnO5 trigonal bipyramid. There are a spread of Mn–O bond distances ranging from 2.07–2.28 Å. In the third Mn2+ site, Mn2+ is bonded to five O2- atoms to form distorted MnO5 trigonal bipyramids that share corners with two equivalent ZnO5 trigonal bipyramids, corners with four MnO5 trigonal bipyramids, edges with two equivalent MnO5 trigonal bipyramids, and a faceface with one ZnO5 trigonal bipyramid.
