Abstract: | The crystal structure of the ternary boride Y2Pd14B5, space group I41/amd, a=8.484(2) Å, c=16.490(3) Å, V=1186.98 Å3, Z=4, was refined down to R=0.0475, wR2=0.1276 from single crystal X-ray diffraction data. Two types of coordination for boron atoms were observed: the coordination sphere for the B1 atom is a trigonal prism with one additional atom; the B2 atom has only four neighboring atoms which form a square. No boron–boron contact was observed. Analysis of the Y2Pd14B5 crystal structure shows the existence of a correlation between this structure and the Sc4Ni29B10 structure type. Magnetization and AC susceptibility measurements indicate that there is no superconducting or magnetic transition in Y2Pd14B5 down to 2 K. |
