Figure 1
The molecular components of compound (I), showing the atom-labelling scheme. Displacement ellipsoids are drawn at the 30% probability level and the alternative sites N1A and N1B each have 50% occupancy [symmetry code: (iv) 1 − x, 1 − y, 1 − z]. The 50% occupancy sites C2A/C2B and C3A/C3B are almost coincident and the H atoms bonded to these disordered C atoms have been omitted for the sake of clarity. |
