Materials Data on Ca2Mn2B4O13 by Materials Project
Abstract
Ca2Mn2B4O13 crystallizes in the orthorhombic Pbam space group. The structure is three-dimensional. Ca2+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of Ca–O bond distances ranging from 2.30–2.50 Å. There are three inequivalent Mn5+ sites. In the first Mn5+ site, Mn5+ is bonded to six O2- atoms to form a mixture of edge and corner-sharing MnO6 octahedra. The corner-sharing octahedral tilt angles are 17°. There are two shorter (1.99 Å) and four longer (2.15 Å) Mn–O bond lengths. In the second Mn5+ site, Mn5+ is bonded to six O2- atoms to form a mixture of edge and corner-sharing MnO6 octahedra. The corner-sharing octahedral tilt angles are 17°. There are four shorter (1.92 Å) and two longer (2.23 Å) Mn–O bond lengths. In the third Mn5+ site, Mn5+ is bonded to six O2- atoms to form a mixture of edge and corner-sharing MnO6 octahedra. The corner-sharing octahedral tilt angles are 18°. There are a spread of Mn–O bond distances ranging from 1.87–2.16 Å. There are three inequivalent B3+ sites. In the first B3+ site, B3+ is bonded to four O2- atoms to form corner-sharing BO4 tetrahedra. There are a spread of B–O bond distances rangingmore »

In the sixth O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one Ca2+ and two B3+ atoms. In the seventh O2- site, O2- is bonded in a distorted trigonal non-coplanar geometry to one Ca2+ and two Mn5+ atoms. In the eighth O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one Ca2+ and two B3+ atoms.
