Figure 3 Ball-and-stick drawings of F⋯H binded layers (layer group p21/b11) in (Ia; left; a view along a-axis; N1=[D22(4)]H1′D22(4), N2=[(8)]H2,H1′) and in (I) [right; a view along (1, 0, 1) direction; N1=[D22(4)]H4D22(4), N2=[(8)]H2,H4]. The F⋯H contacts are depicted as dotted lines. Symmetry diagrams for layer group p21/b11 are also provided in pink colour [a′ = 11.988, b′ = 11.258 Å for (Ia) and a′ = 9.7901 (9), 12.0377 (9) Å for (I); the inversion centres are omitted for clarity]. For description of the graph set notation, see: Etter et al. (1990), Bernstein et al. (1995), Grell et al. (1999). |
