(a) Transformation of the hydrogen-bonding network in 1 to the network found in 2 by incorporation of crystal water. (b) The two-dimensional hydrogen-bonding network in 2. Rows of alternating R42(8) motifs (hydrogen bonds highlighted in blue and magenta, respectively) are connected via discrete N—H⋯O hydrogen bonds (highlighted in yellow). Phenyl rings and CH2 H atoms are omitted for clarity. |
