The structure described by UCuSi crystallizes in the hexagonal P-6m2 space group. U(1) is bonded in a 14-coordinate geometry to two equivalent U(1), six equivalent Cu(1), and six equivalent Si(1) atoms. Cu(1) is bonded in a 11-coordinate geometry to six equivalent U(1), two equivalent Cu(1), and three equivalent Si(1) atoms. Si(1) is bonded in a 11-coordinate geometry to six equivalent U(1), three equivalent Cu(1), and two equivalent Si(1) atoms. is represented by the CIF card [CIF]
