文摘

N′,N″,N′′′-Tris(pyrid-4-ylmethyl)-1,3,5-benzenetricarboxamide (TPMBA-4) reacts with Cu(BF₄)₂·6H₂O to form a zero-dimensional cagelike complex [Cu^II₆(OH)₆(TPMBA-4)₈](BF₄)₃(OH)₃·85H₂O (1). Interestingly, X-ray crystallographic analysis revealed that large (H₂O)₇₆(OH)₆ clusters with outer-shell (H₂O)₅₆(OH)₆ and inner-hosted (H₂O)₂₀ ones are encapsulated in the cavity of 1. It presents a new mode of association of water molecules for research on water or ice.
