Figure 5
The structure of (III), showing the atom-labeling scheme. Displacement ellipsoids are drawn at the 40% probability level, H atoms are shown as small spheres of arbitrary radii and N atoms are shaded gray. Coordination bonds are shown with open lines and the trifurcated hydrogen bonding is indicated by dashed lines. [Symmetry codes: (i) −x + 1, −y + 1, −z + 1; (ii) −x − 1, −y, −z.] |
