Abstract

The reaction of Zn(NO ₃) ₂ ·6H ₂O with multifunctional ligand 4-(2-pyridyl)-6-(4-pyridyl)-2-aminopyrimidine (H ₂L) leads to a circular hexanuclear zinc complex [Zn ₆(HL) ₆(H ₂L) ₆·(NO ₃) ₆·26H ₂O (1), confirmed by single-crystal X-ray diffraction. In the [Zn ₆(HL) ₆(H ₂L) ₆] ⁶⁺ cation, six zinc centers are arranged in a chairlike conformation and 12 ligands fulfill bridging and terminal functions, respectively. The particular interest of complex 1 is the formation of a unique water cluster (H ₆O) ₂₆ composed of a clathrate (H ₂O) ₂₀ core and six dangling water molecules, and the clathrate (H ₂O) ₂₀ core is structurally similar to the famous "Bucky water" (H ₂O) ₂₀. Furthermore, the water molecules and the nitrate ions are assembled into an interesting negative three-dimensional (3D) framework through hydrogen bonds, and the [Zn ₆(HL) ₆(H ₂L) ₆] ⁶⁺ cations just locate in the cavities of the anionic 3D network. To gain insight into the stability of (H ₂O) ₂₀ observed in complex 1, we isolate the water cluster from its environments and compare its stability with "Bucky water" (H ₂O) ₂₀ by a theoretical calculation method. Complex 1 displays room temperature photoluminescence.
