BaTaO2N is (Cubic) Perovskite-derived structured and crystallizes in the tetragonal P4/mmm space group. Ba(1) is bonded to four equivalent N(1) and eight equivalent O(1) atoms to form BaN4O8 cuboctahedra that share corners with twelve equivalent Ba(1)N4O8 cuboctahedra, faces with six equivalent Ba(1)N4O8 cuboctahedra, and faces with eight equivalent Ta(1)N2O4 octahedra. Ta(1) is bonded to two equivalent N(1) and four equivalent O(1) atoms to form TaN2O4 octahedra that share corners with six equivalent Ta(1)N2O4 octahedra and faces with eight equivalent Ba(1)N4O8 cuboctahedra. The corner-sharing octahedra are not tilted. N(1) is bonded in a distorted linear geometry to four equivalent Ba(1) and two equivalent Ta(1) atoms. O(1) is bonded in a distorted linear geometry to four equivalent Ba(1) and two equivalent Ta(1) atoms.
