The material described by La2Al(OsB)2 crystallizes in the monoclinic C2/c space group. There are two inequivalent La sites. In the first La site, La(1) is bonded in a 4-coordinate geometry to two equivalent Al(1), two equivalent B(1), and three equivalent B(2) atoms. In the second La site, La(2) is bonded in a 6-coordinate geometry to three equivalent Al(1), one B(2), and three equivalent B(1) atoms. There are two inequivalent Os sites. In the first Os site, Os(1) is bonded in a 5-coordinate geometry to three equivalent Al(1), one B(1), and one B(2) atom. In the second Os site, Os(2) is bonded in a 4-coordinate geometry to one Al(1), one B(1), and two equivalent B(2) atoms. Al(1) is bonded in a 10-coordinate geometry to two equivalent La(1), three equivalent La(2), one Os(2), three equivalent Os(1), and one Al(1) atom. There are two inequivalent B sites. In the first B site, B(1) is bonded to two equivalent La(1), three equivalent La(2), one Os(1), and one Os(2) atom to form a mixture of distorted edge and corner-sharing BLa5Os2 pentagonal bipyramids. In the second B site, B(2) is bonded in a 7-coordinate geometry to one La(2), three equivalent La(1), one Os(1), and two equivalent Os(2) atoms. is represented by the CIF card [CIF]
