The structure described by La4Co3O10 crystallizes in the tetragonal I4/mmm space group. There are two inequivalent La sites. In the first La site, La(1) is bonded to four equivalent O(1), four equivalent O(2), and four equivalent O(4) atoms to form LaO12 cuboctahedra that share corners with eight equivalent La(1)O12 cuboctahedra, faces with five equivalent La(1)O12 cuboctahedra, faces with four equivalent Co(1)O6 octahedra, and faces with four equivalent Co(2)O6 octahedra. In the second La site, La(2) is bonded in a 9-coordinate geometry to four equivalent O(1) and five equivalent O(3) atoms. There are two inequivalent Co sites. In the first Co site, Co(1) is bonded to one O(2), one O(3), and four equivalent O(1) atoms to form CoO6 octahedra that share  a cornercorner with one Co(2)O6 octahedra, corners with four equivalent Co(1)O6 octahedra, and faces with four equivalent La(1)O12 cuboctahedra. The corner-sharing octahedra are not tilted. In the second Co site, Co(2) is bonded to two equivalent O(2) and four equivalent O(4) atoms to form CoO6 octahedra that share corners with two equivalent Co(1)O6 octahedra, corners with four equivalent Co(2)O6 octahedra, and faces with eight equivalent La(1)O12 cuboctahedra. The corner-sharing octahedra are not tilted. There are four inequivalent O sites. In the first O site, O(1) is bonded to two equivalent La(1), two equivalent La(2), and two equivalent Co(1) atoms to form a mixture of distorted edge, face, and corner-sharing OLa4Co2 octahedra. The corner-sharing octahedral tilt angles range from 0-62°. In the second O site, O(2) is bonded to four equivalent La(1), one Co(1), and one Co(2) atom to form a mixture of distorted edge, face, and corner-sharing OLa4Co2 octahedra. The corner-sharing octahedral tilt angles range from 0-62°. In the third O site, O(3) is bonded in a 6-coordinate geometry to five equivalent La(2) and one Co(1) atom. In the fourth O site, O(4) is bonded to four equivalent La(1) and two equivalent Co(2) atoms to form a mixture of distorted edge, face, and corner-sharing OLa4Co2 octahedra. The corner-sharing octahedral tilt angles range from 0-59°. is represented by the CIF card [CIF]
