The Pna21 polytype of 1 viewed down [010] with (a) molecules colored according to symmetry equivalence, (b) molecules represented by red (pointing toward the reader) and yellow (pointing away) arrows and (c) layer interfaces indicated by a black polygonal chain. In (b) symmetry elements of the space group (black) and non-space group symmetry elements (blue) are given by the common symbols. Additional translation along [010] is given to the right. Inter- and intramolecular hydrogen bonds are represented in (a) by black and red dashed lines, respectively. The geometric elements discussed in the text are marked by their printed symbol in (b). Atom colors and ellipsoids in (c) as in Fig. 2[link].
