The material structure described by LaOs2Al2B crystallizes in the tetragonal P4/mmm space group. La(1) is bonded in a distorted linear geometry to two equivalent B(1) atoms. Os(1) is bonded to four equivalent Al(1) and two equivalent B(1) atoms to form a mixture of face, corner, and edge-sharing OsAl4B2 octahedra. The corner-sharing octahedra are not tilted. Al(1) is bonded in a 4-coordinate geometry to four equivalent Os(1) atoms. B(1) is bonded to two equivalent La(1) and four equivalent Os(1) atoms to form corner-sharing BLa2Os4 octahedra. The corner-sharing octahedra are not tilted. is represented by the Crystallographic Information File (CIF) [CIF]
