Crystal structure of URu4Si2, a new Ru-rich phase in the U–Ru–Si ternary system
Abstract
A novel ternary silicide, URu4Si2, has been found in the Ru-rich corner of the U–Ru–Si ternary system. It crystallizes in an orthorhombic unit cell, a = 11.1322(4) Å, b = 4.0823(2) Å, c = 9.0612(5) Å, with space group Pnma and seven occupied 4c atomic positions, corresponding to the YRh4Ge2 structure-type, an ordered variant of the BaHg6 type.
