Abstract

The structure of an antimony-rich pinakiolite from the Långban mine in Sweden has been investigated by single crystal X-ray diffraction techniques. The space group symmetry used to describe the structure is C2/m, Z = 8, with the unit cell dimensions a = 21.773(4), b = 6.153(2), c = 5.327(2) and β = 94.38(2)°. The derived structural model has been refined versus the 553 most significant reflections with I > 3 · σ(I) and sin(θ)/λ ≤ 0.8 Å−1 to an R-value of 0.047. The results yield the composition Mg1.90(1)Mn0.91(1)Sb0.19(1)O2BO3 in reasonable agreement with the composition Mg1.83Mn0.91Sb0.26O2BO3 found by EDS analysis on the same crystal as was used for the X-ray data collection.

The X-ray diffraction studies indicate some disorder in the crystals. The present study, which is based on the non-diffuse X-ray diffraction intensities, only gives a slightly idealized structural model. The results indicate metal ion distributions largely in agreement with those found in other members of the pinakiolite family. The presence of infinite rows of heavily distorted edgesharing coordination octahedra around the Mn3+ ions is a relevant factor for the occurrence of extended metal position disorder in adjacent rows of octahedra.
