Figure 4
Part of the crystal structure of (II) , showing the formation of a centrosymmetric R22(14) dimer. The atom coordinates and atom labelling are those in the original publication (Cunico et al., 2007 ) and, for the sake of clarity, H atoms not involved in the motif shown have been omitted. The atoms marked with an asterisk (*) are at the symmetry position (2 − x, −y, −z). |
