SmLaB12 is Calcium hexaboride-derived structured and crystallizes in the cubic Fm-3m space group. Sm(1) is bonded in a 24-coordinate geometry to twenty-four equivalent B(1) atoms. La(1) is bonded in a 24-coordinate geometry to twenty-four equivalent B(1) atoms. B(1) is bonded in a 5-coordinate geometry to two equivalent Sm(1), two equivalent La(1), and five equivalent B(1) atoms.
SmLaB12 is Calcium hexaboride-derived structured and crystallizes in the cubic Fm-3m space group. Sm(1) is bonded in a 24-coordinate geometry to twenty-four equivalent B(1) atoms.
