LaIr2B2C crystallizes in the tetragonal I4/mmm space group. La(1) is bonded in a distorted square co-planar geometry to four equivalent C(1) atoms. Ir(1) is bonded to four equivalent B(1) atoms to form a mixture of distorted corner and edge-sharing IrB4 tetrahedra. B(1) is bonded in a distorted single-bond geometry to four equivalent Ir(1) and one C(1) atom. C(1) is bonded in a distorted linear geometry to four equivalent La(1) and two equivalent B(1) atoms.
