American Mineralogist (2008) 93 (11-12): 1787–1798.
.... Relations between layer match and the modulation vector, divergence of layer stackings of the two components, and reasons for the modulation and for the pronounced disorder of the Q component, as well as the differences and similarities with levyclaudite, franckeite, and synthetic layer-misfit compounds...

American Mineralogist (2011) 96 (11-12): 1686–1702.
..., the standing problem of structure-based chemical formulas of the members of the cylindrite-franckeite family has been the distribution of iron and antimony between the Q and H layers and the valence of iron in these compounds. Since the description of the structure of levyclaudite ( Evain et al. 2006...

... alternation of two types of layers (pseudotetragonal Q, and pseudo-hexagonal H), with an asymmetric interface (like a unit-cell syntactic intergrowth), as exemplified by the crystal structures of cylindrite ( Makovicky et al , 2008 ) and its Cu derivative, lévyclaudite ( Evain et al , 2006 ). In natural...

... substitution in these sites. The eccentricity of Bi can be explained by the stereo chemical activity of its lone electron pair, whereas the eccentric position of Sn is a result of its small size in comparison with the size of the octahedral void. The average octahedral Sn IV -S distance (2.577) in levyclaudite...

... of the cylindrite-levyclaudite solid solution ( Evain et al ., 2006 ). While Sn is present in the H layer exclusively as Sn 4+ , some Sn 2+ may be incorporated in the Q layer substituting for Pb 2+ ( Bernhardt, 1984 ; Amthauer, 1986 ) ( Table 5 b ; Fig. 13 ). On the basis of a total of 3.69 Me...

... of 0.7022, i.e., a very small change in the resulting valence distribution in this variable-fit series ( Makovicky and Hyde 1992 ). Levyclaudite is a Pb rich, Cu-Bi containing analog of cylindrite. Franckeite (Table 13 ) is closely related to cylindrite and displays all the above variations...
