“…However, compared with the (RE/An)XY and (RE/An)X 2 Y 2 systems, the (RE/An) 2 X 3 Y 5 compounds discovered so far as well as the research works on their physical properties are still relatively few. In particular, the physical properties and/or crystal structures of An 2 X 3 Y 5 compounds have been reported only for several silicides [16][17][18][19][20][21][22][23][24][25][26][27][28]. To date, there is no report on the An-based germanide An 2 X 3 Ge 5 .…”

A new ternary uranium germanide U2Rh3Ge5 has been successfully synthesized and investigated by means of magnetic susceptibility χ(T, H), isothermal magnetization M(T, H), electrical resistivity ρ(T), and specific heat C(T, H) measurements. This compound is found to crystallize in the U2Co3Si5-type orthorhombic structure. The low-field χ(T) shows a clear peak at T N = 41.5 K corresponding to an antiferromagnetic transition. The M(H) curve measured up to 70 kOe exhibits an H-linear behavior at 2 K with very small induced magnetic moments, while it shows upward curvature with increasing temperature, implying the possible presence of a metamagnetic transition in high-field region above 70 kOe. As the temperature decreases, ρ(T) increases slowly at T > T N and decreases rapidly at T < T N, which can be understood based on a semiconductor-like narrow band gap model (or the c-f hybridization effect) and an antiferromagnetic spin-wave model, respectively. No evidence of heavy-fermion behavior or superconductivity transition is observed at temperatures as low as 0.4 K. The obtained experimental results are discussed by comparing with those reported for the isomorphic compound U2Ir3Si5 and the quasi-isomorphic compound U2Rh3Si5.

Si 5 Compound. -The title compound is characterized by powder XRD and DFT calculations. It crystallizes in the monoclinic space group C2/c with Z = 4. Close crystallographic relationships between the title compound and the orthorhombic U2Co3Si5 phase are discussed. The structure of U2Fe3Si5 can be considered as integration of a three-dimensional network of interconnected U-polyhedra with chains of Fe-polyhedra. The stability of this structure is due to the hybridization between f-electrons of U and d-electrons of Fe. -(ZENOU*, V. Y.; FUKS, D.; TALIANKER, M.; J. Alloys Compd. 529 (2012) 122-127, http://dx.
