The material described by YBN2 is beta beryllia-derived structured and crystallizes in the tetragonal P-4m2 space group. Y(1) is bonded in a 4-coordinate geometry to four equivalent N(1) atoms. B(1) is bonded to four equivalent N(1) atoms to form corner-sharing BN4 tetrahedra. N(1) is bonded to two equivalent Y(1) and two equivalent B(1) atoms to form corner-sharing NY2B2 tetrahedra. is represented by the Crystallographic Information File (CIF) [CIF]
