The compound described by EuNbO2N is (Cubic) Perovskite-derived structured and crystallizes in the tetragonal P4/mmm space group. Eu(1) is bonded to four equivalent N(1) and eight equivalent O(1) atoms to form EuN4O8 cuboctahedra that share corners with twelve equivalent Eu(1)N4O8 cuboctahedra, faces with six equivalent Eu(1)N4O8 cuboctahedra, and faces with eight equivalent Nb(1)N2O4 octahedra. Nb(1) is bonded to two equivalent N(1) and four equivalent O(1) atoms to form NbN2O4 octahedra that share corners with six equivalent Nb(1)N2O4 octahedra and faces with eight equivalent Eu(1)N4O8 cuboctahedra. The corner-sharing octahedra are not tilted. N(1) is bonded in a distorted linear geometry to four equivalent Eu(1) and two equivalent Nb(1) atoms. O(1) is bonded in a distorted linear geometry to four equivalent Eu(1) and two equivalent Nb(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
