Abstract:Single crystals of lithium iron tungstate, LiFe(WO4)2, were obtained using a high‐temperature solution growth method. The analysis was conducted using the monoclinic space group C2/c, with β = 90.597 (2)°, giving R1 = 0.0177. The Li and Fe atoms lie on twofold axes. The structure can also be refined using the orthorhombic space group Cmcm, giving slightly higher residuals. The experimental value of β and the residuals mitigate in favour of the monoclinic description of the structure. Calculated bond‐valence sums for the present results are closer to expected values than those obtained using the results of a previously reported analysis of this structure.
