The ternary system cerium–rhodium–silicon

Crystal structure and physical properties of Ce3Rh5Si

“…The obtained values a = 1.5284(1) nm, b = 0.5511(1) nm, c = 0.7536(1) nm are in good agreement with those reported in Ref. [1]. Further analysis of the X-ray pattern was carried out using the FULLPROF program [3], and the charge-flipping algorithm implemented in the program SUPERFLIP [4].…”

“…As pointed out in Ref. [1], up to 6.7 at. % of Si can substitute Rh in the binary compound CeRh 2 (MgCu 2 -type), hence forming the Ce(Rh 1−x Si x ) 2 phases.…”

“…Recently, the ternary phase diagram Ce-Rh-Si has been carefully investigated and the formation of several novel compounds has been established [1]. Among them is a phase with the composition within the range 8.…”

Bismuth Flux Growth of CeRh6Ge4 and CeRh2Ge2 Single Crystals

“…The phosphides RERh 6 P 4 (RE = Sc, Yb, Lu) [23] adopt a superstructure of the LiCo 6 P 4 type through two translationengleiche symmetry reductions. CeRh 6 Si 4 [37] and CeRh 6 Ge 4 are the first tetrelides that crystallize with this structure type. Interestingly, this structure type had also been observed for the chemically related compounds KIn 6 Au 4 and RbIn 6 Au 4 [38] which can be classified as aurides.…”

Synthesis of Ce2Rh3Ge5 Crystals from a Bismuth Flux

“…Careful examination of the data set revealed a body-centered orthorhombic lattice, and the systematic extinctions were compatible with space group Ibam. The atomic parameters of the crystal-chemically closely related phase [24] were taken as starting values, and the structure was refined with anisotropic displacement parameters for all atoms with SHELXL-97 (full-matrix least-squares on F 2 o ) [25,26]. In a separate refinement of the occupancy parameters no deviation from the ideal composition was observed.…”
