Topochemically Reduced Rh-containing Oxides

Abstract: Topochemical reduction allows the preparation of novel anion-deficient and anion-exchanged solids, not accessible by conventional synthesis routes. There is growing interest in applying topochemical reduction to transition metal oxides to form oxyhydride (containing both O2- and H- anions) or oxide-ion deficient materials, as these phases can exhibit electronic and magnetic behaviour which is strikingly different from the corresponding all-oxide starting materials. Following this synthesis strategy we have prepared a series of reduced/anion-exchanged phases from rhodium-containing complex oxides: LaSrMnRhO6 is converted to LaSrMnRhO4 while LaSr3MnRhO8 is converted to LaSr3MnRhO6.5; La2CoRhO6 is converted to the oxyhydride La2CoRhO4H2 while Ca3CoRhO6 is converted to Ca3CoRhO5H. We propose to collect high resolution neutron diffraction data from these reduced materials to determine their crystal structures (especially the location of the oxide and hydride ions) and also their low-temperature magnetic structures.
