Abstract

The crystal structure of bonshtedtite, Na3Fe(PO4)(CO3) (monoclinic, P21/m, a = 5.137(4), b = 6.644(4), c = 8.908(6) Å, β = 90.554(14)°, V = 304.0(4) Å3, Z = 2) has been refined to R 1 = 0.041 on the basis of 1314 unique reflections. The structure is similar to that of other minerals of the bradleyite group. It is based on the [Fe(PO4)(CO3)]3− layers oriented parallel to (001). The layers are formed by corner-sharing PO4 tetrahedra and FeO4(CO3) complexes, where FeO6 tetrahedra and CO3 triangles are edge-shared. The topology of the octa-tetrahedral layer in bonshtedtite is similar to that of the autunite-group minerals, but it differs from the latter in terms of local topological properties.
