Packing diagram illustrating intermolecular contacts (dashed lines) in the structure of (I). Unique contacts are labelled as follows: 1: N2⋯O3 = 2.905 (4) Å, O3 in the molecule at (−x, 1 − y, −z); 2: N1⋯O1 = 2.920 (3) Å, O1 in the molecule at (x,1/2 − y,- + z); 3: N3⋯O1 = 3.121 (3) Å, O1 in the molecule at (1 − x, + y, − z); 4: N3⋯N2 = 3.214 (2) Å, N2 in the molecule at (1 + x, − y, + z); 5: C3⋯O2 = 3.416 (3) Å, O2 in the molecule at (−x, + y, − − z). Contacts calculated and illustrated using PLATON (Spek, 2003; program version 280604). |
