The structure described by UNiSi crystallizes in the orthorhombic Pnma space group. U(1) is bonded in a 11-coordinate geometry to two equivalent U(1), four equivalent Ni(1), and five equivalent Si(1) atoms. Ni(1) is bonded in a 8-coordinate geometry to four equivalent U(1) and four equivalent Si(1) atoms. Si(1) is bonded in a 9-coordinate geometry to five equivalent U(1) and four equivalent Ni(1) atoms. is represented by the CIF card [CIF]
