CeIr3BSi crystallizes in the hexagonal P-6m2 space group. Ce(1) is bonded in a 18-coordinate geometry to twelve equivalent Ir(1), three equivalent B(1), and three equivalent Si(1) atoms. Ir(1) is bonded in a distorted rectangular see-saw-like geometry to four equivalent Ce(1), two equivalent B(1), and two equivalent Si(1) atoms. B(1) is bonded in a 9-coordinate geometry to three equivalent Ce(1) and six equivalent Ir(1) atoms. Si(1) is bonded in a 6-coordinate geometry to three equivalent Ce(1) and six equivalent Ir(1) atoms.
