The crystal structure described by La9CSb5O4 crystallizes in the tetragonal P4/n space group. There are three inequivalent La sites. In the first La site, La(1) is bonded in a distorted single-bond geometry to one C(1), one Sb(1), and four equivalent Sb(2) atoms. In the second La site, La(2) is bonded in a distorted single-bond geometry to one Sb(1), four equivalent Sb(2), and one O(1) atom. In the third La site, La(3) is bonded in a 4-coordinate geometry to one C(1), two equivalent Sb(2), and three equivalent O(1) atoms. C(1) is bonded to one La(1) and four equivalent La(3) atoms to form distorted CLa5 trigonal bipyramids that share  a cornercorner with one Sb(1)La5 square pyramid, corners with four equivalent O(1)La4 tetrahedra, and edges with four equivalent O(1)La4 tetrahedra. There are two inequivalent Sb sites. In the first Sb site, Sb(1) is bonded to one La(1) and four equivalent La(2) atoms to form distorted SbLa5 square pyramids that share corners with four equivalent O(1)La4 tetrahedra and  a cornercorner with one C(1)La5 trigonal bipyramid. In the second Sb site, Sb(2) is bonded in a 7-coordinate geometry to one La(1), two equivalent La(3), and four equivalent La(2) atoms. O(1) is bonded to one La(2) and three equivalent La(3) atoms to form OLa4 tetrahedra that share  a cornercorner with one Sb(1)La5 square pyramid, corners with four equivalent O(1)La4 tetrahedra,  a cornercorner with one C(1)La5 trigonal bipyramid,  an edgeedge with one O(1)La4 tetrahedra, and  an edgeedge with one C(1)La5 trigonal bipyramid. is represented by the CIF card [CIF]
