Materials Data on Mn2CoO4 by Materials Project

CoMn2O4 is Spinel structured and crystallizes in the tetragonal I4_1/amd space group. The structure is three-dimensional. Mn2+ is bonded to six equivalent O2- atoms to form MnO6 octahedra that share corners with six equivalent CoO4 tetrahedra and edges with six equivalent MnO6 octahedra. There are four shorter (1.98 Å) and two longer (2.29 Å) Mn–O bond lengths. Co4+ is bonded to four equivalent O2- atoms to form CoO4 tetrahedra that share corners with twelve equivalent MnO6 octahedra. The corner-sharing octahedra tilt angles range from 55–59°. All Co–O bond lengths are 2.01 Å. O2- is bonded in a distorted rectangular see-saw-like geometry to three equivalent Mn2+ and one Co4+ atom.

CoMn₂O₄为尖晶石结构（Spinel structured），结晶于四方晶系I4₁/amd空间群。该结构为三维框架。二价锰离子（Mn²+）与六个等价的二价氧离子（O²-）配位形成MnO₆八面体，该八面体与六个等价的CoO₄四面体共享顶角，同时与六个等价的MnO₆八面体共享棱边。Mn–O键存在两种键长：四个较短键长为1.98 Å，两个较长键长为2.29 Å。四价钴离子（Co⁴+）与四个等价的O²-配位形成CoO₄四面体，该四面体与十二个等价的MnO₆八面体共享顶角。共顶八面体的倾斜角范围为55°~59°。所有Co–O键长均为2.01 Å。O²-以畸变的矩形跷跷板型几何构型与三个等价的Mn²+及一个Co⁴+配位成键。
