Abstract
Amino acid-functionalized Ni4(OH)3Cl tetrahedral clusters containing peptide linkages are linked into hexagonal planes connected pairwise into layers by neutral linkers. These layers stack to afford an open-framework structure, with large cavities occupied by non-ice-geometry (H2O)16 clusters. The layer stacking motif and the guest cluster geometry are both determined by an intricate hierarchy of hydrogen-bonding interactions defined by the array of peptides supported by the tetrahedral units. The (H2O)16 cluster adopts a non-ice-like structure due to the resulting highly symmetrical arrangement of the amide groups around the water molecules and the participation of two hydroxide anions per cluster.
