Figure 3
(a) Stereodrawing showing the coordination of hydrogen-bond donors around a Cl− anion (see Table 2 for symmetry operators). (b) Tape motif along the b axis generated from Cα—H⋯O hydrogen bonds. O1* is at (x, y + 1, z), O1′ at (−x + , y + , −z + 1). Side chains have been truncated beyond Cβ. |
