The structure described by La2CoSiO2 crystallizes in the tetragonal P4/mmm space group. La(1) is bonded in a 4-coordinate geometry to four equivalent Si(1) and four equivalent O(1) atoms. Co(1) is bonded in a square co-planar geometry to four equivalent O(1) atoms. Si(1) is bonded in a body-centered cubic geometry to eight equivalent La(1) atoms. O(1) is bonded to four equivalent La(1) and two equivalent Co(1) atoms to form a mixture of corner, edge, and face-sharing OLa4Co2 octahedra. The corner-sharing octahedra are not tilted. is represented by the CIF card [CIF]
