The structure described by YCo11Ti crystallizes in the orthorhombic Imm2 space group. Y(1) is bonded in a 20-coordinate geometry to one Ti(1), one Co(5), two equivalent Co(1), two equivalent Co(2), two equivalent Co(6), four equivalent Co(3), and eight equivalent Co(4) atoms. Ti(1) is bonded in a 14-coordinate geometry to one Y(1), one Co(5), two equivalent Co(2), two equivalent Co(3), four equivalent Co(4), and four equivalent Co(6) atoms. There are six inequivalent Co sites. In the first Co site, Co(1) is bonded to two equivalent Y(1), two equivalent Co(3), two equivalent Co(5), two equivalent Co(6), and four equivalent Co(4) atoms to form distorted CoY2Co10 cuboctahedra that share corners with eight equivalent Co(4)Y2TiCo9 cuboctahedra, edges with two equivalent Co(1)Y2Co10 cuboctahedra, edges with four equivalent Co(4)Y2TiCo9 cuboctahedra, and faces with eight equivalent Co(4)Y2TiCo9 cuboctahedra. In the second Co site, Co(2) is bonded in a 12-coordinate geometry to two equivalent Y(1), two equivalent Ti(1), two equivalent Co(3), two equivalent Co(6), and four equivalent Co(4) atoms. In the third Co site, Co(3) is bonded in a 12-coordinate geometry to two equivalent Y(1), one Ti(1), one Co(1), one Co(2), one Co(5), two equivalent Co(6), and four equivalent Co(4) atoms. In the fourth Co site, Co(4) is bonded to two equivalent Y(1), one Ti(1), one Co(1), one Co(2), one Co(5), two equivalent Co(3), two equivalent Co(4), and two equivalent Co(6) atoms to form distorted CoY2TiCo9 cuboctahedra that share corners with two equivalent Co(1)Y2Co10 cuboctahedra, corners with ten equivalent Co(4)Y2TiCo9 cuboctahedra,  an edgeedge with one Co(1)Y2Co10 cuboctahedra, edges with four equivalent Co(4)Y2TiCo9 cuboctahedra, faces with two equivalent Co(1)Y2Co10 cuboctahedra, and faces with six equivalent Co(4)Y2TiCo9 cuboctahedra. In the fifth Co site, Co(5) is bonded in a 1-coordinate geometry to one Y(1), one Ti(1), two equivalent Co(1), two equivalent Co(3), four equivalent Co(4), and four equivalent Co(6) atoms. In the sixth Co site, Co(6) is bonded in a 14-coordinate geometry to one Y(1), two equivalent Ti(1), one Co(1), one Co(2), one Co(6), two equivalent Co(3), two equivalent Co(5), and four equivalent Co(4) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
