Self-assembly of a symmetric tetracopper box-grid with guest trapping in the solid state

Supramolecular Assemblies of a Bis(terpyridine) Ligand and of its [2×2] Grid-type ZnII and CoII Complexes on Highly Ordered Pyrolytic Graphite

“…Insertion of benzene solvent molecules between ligands in grid-type complexes has been observed. [17] The 27 ä period in the other direction must then be constituted by couples of two complexes. Based on this consideration we suggest the structural arrangement of 7 a on graphite shown in Figure 4.…”

Self‐Assembly and Characterization of Grid‐Type Copper(I), Silver(I), and Zinc(II) Complexes

“…These grids are thermodynamically most stable when metal ions of tetrahedral coordination geometry are combined with a planar ligand containing bidentate binding subunits. [17,18,[29][30][31][32][33][34][35][36][37][38][39][40] The first [2 × 2] grid type was obtained with copper() ions, [17] and copper() grid complexes have recently attracted much attention because of their well-defined supramolecular architectures and their interesting properties, such as special optical, [35] magnetic, [36] and electrochemical features or the atypical geometry of the grid structure. [37] Silver() has also been used as an assembling ion and, thanks to the flexibility of its coordination sphere, has yielded sophisticated coordination architectures such as [3 × 3] [ 29] and [(2 × 5) 2 ] [6] multinuclear grids.…”

Spacer Control of Directionality in Supramolecular Helicates Using an Inexpensive Approach

“…

The double-helical structure has provided an important forum for the evolution of metallo-supramolecular construction principles.[1] Their application in other systems has led to a plethora of supramolecular architectures such as boxes, [1±3] grids, [4] and cylinders. [5] While the basic features of the design necessary to assemble a double helix are now fairly well established, [1] challenges in defining the precise topology or conformation of the helical superstructure remain.
