Figure 5
A representation of the chain structure (shaded area) constructed by C5—H5A⋯O4iv hydrogen bonds (dashed green lines) between dimer entities. Green, purple and magenta symbols represent the positions of the centres of inversion within the R22(10), R44(12) and R22(12) motifs, respectively. Also shown is the two-dimensional sheet structure mediated by inversion-related pairs of nonclassical C15—H15A⋯O3v hydrogen bonds (dashed lines) between adjacent chains. (Symmetry codes have been omitted in the image.) |
