Controlling the ratio of 2,2'-bpy to benzene-1,3,5-tricarboxylic acid produces two interesting complexes, namely [Co(2,2'-bpy)₃]·(SO₄)·8.5H₂O (1) and [Cu₂(BTCA) (2,2'-bpy)₄] (OH)·(2,2'-bpy)₀.₅·14H₂O (2) (H₃BTCA = benzene-1,3,5-tricarboxylic acid, 2,2'-bpy = 2,2'-bipyridine). We report the structural evidence in the solid state of discrete lamellar water cluster conformations. These units are found to act as supramolecular glue in the aggregation of cobalt (II) or copper (II) complexes to give three dimensional cage-like networks through hydrogen-bonding. It is interesting that the structure of complex 1 contains a 3D negatively charged cage.
控制 2,2'-联吡啶和均苯三甲酸的比例可以得到两个有趣的配合物，分别为[Co(2,2'-bpy)₃]·(SO₄)·8.5H₂O（1）和[Cu₂(BTCA) (2,2'-bpy)₄] (OH)·(2,2'-bpy)₀.₅·14H₂O（2）（H₃BTCA=均苯三甲酸，2,2'-bpy=2,2'-联吡啶）。我们在固态下报告了这些离散层状水簇构象的结构证据。这些单元被发现作为超分子胶，通过氢键将钴（II）或铜（II）配合物聚集在一起，形成三维笼状网络。有趣的是，配合物 1 的结构包含一个 3D 带负电荷的笼。
