Abstract:
A new Pt-doped yttrium boride of the YB50 family, YB45-xPty, x=2.12, y=0.21 (space group Pbam, a=16.6246(4) Å, b=17.6453(4) Å, c=9.4167(2) Å), has been synthesized by arc-melting pure elements and subsequent annealing at 1123 K. A single crystal has been studied in order to assess the Pt-doping effect on the crystal structure. Insertion of Pt in two 4h interstitial sites of the boron atom framework leads to the transformation of -[B12]-[B12]- icosahedral chain into -[B11]-Pt-[B11]- for 38.6% of them as well as, to a lesser extent, induces the disorder into the [B15] polyhedron and neighboring interstitial B site (97.3% vs 2.7%).
