In the second Ti site, Ti is bonded in a 12-coordinate geometry to four Y and twelve Co atoms. There are six shorter (2.89 Å) and six longer (2.90 Å) Ti–Co bond lengths. There are ten inequivalent Co sites. In the first Co site, Co is bonded to three Y, three Sc, and six Co atoms to form a mixture of face, edge, and corner-sharing CoY3Sc3Co6 cuboctahedra. There are a spread of Co–Co bond distances ranging from 2.46–2.51 Å. In the second Co site, Co is bonded to one Y, three Sc, two equivalent Ti, and six Co atoms to form a mixture of face, edge, and corner-sharing CoYSc3Ti2Co6 cuboctahedra. There are one shorter (2.46 Å) and five longer (2.47 Å) Co–Co bond lengths. In the third Co site, Co is bonded to three Y, three Ti, and six Co atoms to form CoY3Ti3Co6 cuboctahedra that share corners with eighteen CoYSc3Ti2Co6 cuboctahedra, edges with six CoYSc3Ti2Co6 cuboctahedra, and faces with eighteen CoY3Ti3Co6 cuboctahedra. There are a spread of Co–Co bond distances ranging from 2.46–2.49 Å. In the fourth Co site, Co is bonded to six Sc and six Co atoms to form CoSc6Co6 cuboctahedra that share corners with eighteen CoYSc3Ti2Co6 cuboctahedra, edges with six equivalent CoSc6Co6 cuboctahedra, and faces with eighteen CoYSc3Ti2Co6 cuboctahedra. All Co–Co bond lengths are 2.45 Å.
