The hydrogen-bonding networks within a sheet of hydrophilic groups in (I), viewed along the c axis. Darker dashed lines (blue in the electronic version of the paper) indicate hydrogen bonds and lighter dashed lines indicate C—H⋯O interactions. Side-chain atoms of the leucyl residues have been omitted for clarity. [Symmetry codes: (i) x + 1, y, z; (vi) x + 1, y + 1, z; (vii) x − 1, y, z; (viii) x, y − 1, z; (ix) x + 1, y − 1, z.] |
