Figure 2
A packing diagram illustrating hydrogen bonds in (I). Unique contacts are labelled as follow: 1 = N1⋯O2Ai; 2 = N2⋯O4i; 3 = N3⋯O5; 4 = N3⋯O2Aii; 5 = N1A⋯O5Aiii; 6 = N2Ai⋯N3A(x, −2 + y, z); 7 = N3A—H7N⋯O5iv; 8 = N3A—H8N⋯O5Aiv (see Table 1 for symmetry codes and geometry). Contacts calculated and illustrated using PLATON (Spek, 2003; program version 280604). Contact 6 is shown outwith the asymmetric unit for clarity. |
