摘要：

Two examples of structures of obverse/reverse twins are presented. Example (1) is the structure of 2,2,4,4,6,6-hexa-tertbutylcyclotrisiloxane. It crystallizes in R (3) over barc. Example (2) is the structure of [{Li(Me3Si)(3)CAlF3 (thf)}(3)LiF(thf)], tris[lithiuim tetrahydrofuran (trimethylsilyl)methyltrifluoroaluminate]lithium fluoride tetrahydrofuran. It crystallizes in R3. Additional to the obverse/reverse twinning this structure shows merohedral twinning. It will be shown how these two structures can be refined with the SHELXL program.
