Abstract

Samples of YPdCd, Y2Pd2Cd and Y2Cu2Cd were synthesized from the elements by induction melting. The three cadmium phases were characterized through their Guinier powder patterns. YPdCd crystallizes with the hexagonal ZrNiAl-type structure (space group P 6 ‾ 2m; a = 756.0(4) and c = 384.7(2) pm). The structure of Y2Pd2Cd was refined from single-crystal X-ray diffractometer data: Mo2B2Fe type, tetragonal space group P4/mbm, a = 765.33(3), c = 370.30(2) pm, wR2 = 0.0254, 289 F2 values and 12 variables. Y2Pd2Cd is a 1:1 intergrowth structure of CsCl and AlB2 related slabs of compositions ‘YCd’ and ‘YPd2’. The palladium dumb-bells (279 pm Pd–Pd) and the cadmium atoms (301 pm Cd–Pd) form a two-dimensional [Pd2Cd] substructure that is separated by yttrium layers in c direction. Consistent with their crystal structures, the 113Cd solid-state MAS-NMR spectra of Y2Pd2Cd and isotypic Y2Cu2Cd show only one signal characterized by strong Knight shift contributions.

Keywords: yttrium; cadmium intermetallics; crystal structure: solid-state NMR spectroscopy
