Abstract

β-Li3CrO4, isostructural with β-Li3PO4, has been synthesized by two routes. Reaction of Li2CO3 and Cr2O3 in a 5 : 1 mole ratio in flowing Ar at 800 °C yields β-Li3CrO4, with a small amount of Li2O. The Li2CO3, seems to have two functions. It is an essential reactant and acts as a novel oxidant, promoting conversion of CrIII to CrV. Reaction of Li2CO3 and CrO3 in a 3 : 1 mole ratio in flowing Ar also gives phase-pure β-Li3CrO4. Magnetic measurements show Curie–Weiss behaviour in the range 20–300 K with a magnetic moment of 1.70 µB consistent with CrV in tetrahedral coordination. Conductivity measurements show a modest level of electronic conduction.
