Hydroxide flux synthesis and crystal structure of the ordered palladate, LuNaPd{sub 6}O{sub 8}
- Department of Chemistry and Biochemistry, University of South Carolina, Columbia, SC 29208 (United States)
We report the single crystal structure of LuNaPd{sub 6}O{sub 8} grown from a sodium hydroxide flux. The utilization of a hydroxide flux has led to the preparation of the first ordered substitution of a lanthanide metal and an alkali metal on the A-site in a platinum group oxide and the first palladate to contain both a lanthanide metal and an alkali metal. The 1:1 ordered substitution of Lu{sup 3+} and Na{sup +} in place of the commonly observed divalent cation leads to slabs of LuO{sub 8} and NaO{sub 8} cubes bridged together by PdO{sub 4} square planes. The compound crystallizes in the cubic space group Pm-3 (no. 200) with a=5.72500(10) A and is structurally related to other cubic palladium oxides. - Graphical abstract: Unit cell of the ordered palladate, LuNaPd{sub 6}O{sub 8} viewed along the z-direction. The Pd{sup 2+} cations (grey) reside in a square planar coordination environment and bridge together the LuO{sub 8} (blue) and NaO{sub 8} (yellow) cubes.
