The compound described by UCoSi is hexagonal omega structure-derived structured and crystallizes in the orthorhombic Pnma space group. U(1) is bonded to six equivalent Co(1) and six equivalent Si(1) atoms to form a mixture of face and edge-sharing UCo6Si6 cuboctahedra. Co(1) is bonded in a 9-coordinate geometry to six equivalent U(1) and three equivalent Si(1) atoms. Si(1) is bonded in a 9-coordinate geometry to six equivalent U(1) and three equivalent Co(1) atoms. is represented by the CIF file [CIF]
