Abstract
The crystal structure of ferberite has been determined and refined by projections to R values of 7.2% for hk0 reflections and 5.4% for h0l reflections. The structure is based on W and Fe octahedra forming infinite zig-zag chains in the direction of the c axis. Each chain contains just one type of cation and each octahedron is joined to the next by a common edge. Each W-octahedral chain is attached by common corners to four Fe chains, and each Fe chain is also surrounded by four W chains. The atomic configuration is then different from the structure reported for MgWO4, which was believed to be isostructural with the members of the wolframite group, even though the cation positions are proved to be correct.
