The crystal structure described by CeFe11Ti crystallizes in the orthorhombic Imm2 space group. Ce(1) is bonded in a 20-coordinate geometry to one Ti(1), one Fe(5), two equivalent Fe(1), two equivalent Fe(2), two equivalent Fe(6), four equivalent Fe(3), and eight equivalent Fe(4) atoms. Ti(1) is bonded in a 14-coordinate geometry to one Ce(1), one Fe(5), two equivalent Fe(2), two equivalent Fe(3), four equivalent Fe(4), and four equivalent Fe(6) atoms. There are six inequivalent Fe sites. In the first Fe site, Fe(1) is bonded to two equivalent Ce(1), two equivalent Fe(3), two equivalent Fe(5), two equivalent Fe(6), and four equivalent Fe(4) atoms to form distorted FeCe2Fe10 cuboctahedra that share corners with eight equivalent Fe(4)Ce2TiFe9 cuboctahedra, edges with two equivalent Fe(1)Ce2Fe10 cuboctahedra, edges with four equivalent Fe(4)Ce2TiFe9 cuboctahedra, and faces with eight equivalent Fe(4)Ce2TiFe9 cuboctahedra. In the second Fe site, Fe(2) is bonded in a 12-coordinate geometry to two equivalent Ce(1), two equivalent Ti(1), two equivalent Fe(3), two equivalent Fe(6), and four equivalent Fe(4) atoms. In the third Fe site, Fe(3) is bonded in a 12-coordinate geometry to two equivalent Ce(1), one Ti(1), one Fe(1), one Fe(2), one Fe(5), two equivalent Fe(6), and four equivalent Fe(4) atoms. In the fourth Fe site, Fe(4) is bonded to two equivalent Ce(1), one Ti(1), one Fe(1), one Fe(2), one Fe(5), two equivalent Fe(3), two equivalent Fe(4), and two equivalent Fe(6) atoms to form distorted FeCe2TiFe9 cuboctahedra that share corners with two equivalent Fe(1)Ce2Fe10 cuboctahedra, corners with ten equivalent Fe(4)Ce2TiFe9 cuboctahedra,  an edgeedge with one Fe(1)Ce2Fe10 cuboctahedra, edges with four equivalent Fe(4)Ce2TiFe9 cuboctahedra, faces with two equivalent Fe(1)Ce2Fe10 cuboctahedra, and faces with six equivalent Fe(4)Ce2TiFe9 cuboctahedra. In the fifth Fe site, Fe(5) is bonded in a 1-coordinate geometry to one Ce(1), one Ti(1), two equivalent Fe(1), two equivalent Fe(3), four equivalent Fe(4), and four equivalent Fe(6) atoms. In the sixth Fe site, Fe(6) is bonded in a 14-coordinate geometry to one Ce(1), two equivalent Ti(1), one Fe(1), one Fe(2), one Fe(6), two equivalent Fe(3), two equivalent Fe(5), and four equivalent Fe(4) atoms. is represented by the CIF card [CIF]
