| Popis: | The new selenide SnNb5Se9 has been synthesized and characterized by density measurements, X-ray powder diffraction. The cell, determined by U-fit software, derives from that of NbSe2; it presents a superstructure and an important disorder along the c axis, a single crystal study confirms these points. Mo¨ssbauer studies show three types of Sn atom. Magnetic properties show a superconducting behavior at 17.1 K with ∂Hc1/∂T= 71G.K−1 and ∂Hc2/∂T= 5kG.K−1. |
