The material structure described by Be3Mn4Si3SeO12 crystallizes in the cubic P-43n space group. Be(1) is bonded to four equivalent O(1) atoms to form BeO4 tetrahedra that share corners with four equivalent Mn(1)SeO3 tetrahedra and corners with four equivalent Si(1)O4 tetrahedra. Mn(1) is bonded to one Se(1) and three equivalent O(1) atoms to form distorted MnSeO3 tetrahedra that share corners with three equivalent Be(1)O4 tetrahedra, corners with three equivalent Mn(1)SeO3 tetrahedra, and corners with three equivalent Si(1)O4 tetrahedra. Si(1) is bonded to four equivalent O(1) atoms to form SiO4 tetrahedra that share corners with four equivalent Be(1)O4 tetrahedra and corners with four equivalent Mn(1)SeO3 tetrahedra. Se(1) is bonded in a tetrahedral geometry to four equivalent Mn(1) atoms. O(1) is bonded in a trigonal planar geometry to one Be(1), one Mn(1), and one Si(1) atom. is represented by the CIF file [CIF]
