Then, a two-fold rotation axis that related the two twins was drawn. Judging from the experimental procedure, this axis was assigned to the χ 2 axis.

Webrefinement. We also added the sentence ^The fractional volume contribution of the twin components, expressed by BASF parameter according to SHELXL-2014 [27], is reported in Table 1a,b and 2a,b.” in the experimental section 2.2. - Experimental section - XRPD: "Due to pseudo-orthorhombic symmetry associated with WebA typical definition of a twinned crystal is the following: “Twins are regular aggregates consisting of crystals of the same species joined together in some definite mutual orientation” (Giacovazzo, 1992). For this to happen two lattice repeats in the crystal must be of equal length to allow the array of unit cells to pack compactly.
WebQ77: Does SHELXL calculate estimated observed F-values for a single twin component ? George: For the purpose of calculating a difference electron density map and the final Fo/Fc tables (but not of course for refinement) SHELXL partitions the observed intensity in the ratio of the calculated contributions, i.e.
