In contrast to the well‐studied templating properties of cationic and neutral species there are relatively few examples of anion‐templated syntheses. This is attributed to some of the intrinsic properties of anions such as their diffuse nature, pH sensitivity, and their relative high solvation free energies. However, the increasing number of anion‐templated assemblies reported over the past few years demonstrates that these limitations are not as critical as first thought. This review summarizes the most important results on the use of anions as directing agents for the syntheses of a wide range of inorganic and organic assemblies (such as macrocycles, cages, helicates, rotaxanes, and extended structures). It is hoped that this will stimulate a closer look into this emerging area of supramolecular chemistry.

“…Anionic templation is a powerful approach to obtain various interesting products and supramolecular structures,2 especially in the assembly of intriguing huge metal cluster compounds 3. 4 Vilar, Mingos and co‐workers pioneered the assembly of novel halide‐templated rhombohedral silver alkynyl cage compounds [Ag 14 (C≡C t Bu) 12 X] + (X=F, Cl, Br) 5. Subsequently, other groups systematically reported the assembly of silver clusters using various anionic templates such as halide, carbonate, chromate, and polyoxometalates (POMs) 6–8.…”

A novel discrete open high-nuclearity nest-like silver thiolate cluster complex, [Ag33 S3 (StBu)16 (CF3 COO)9 (NO3 )(CH3 CN)2 ](NO3 ) (1), has been isolated with nitrate and S(2-) anions acting as structure-directing templates. Its similar nest-like structure has been assembled into an extended layer [Ag31 S3 (StBu)16 (NO3 )9 ]n (2) by adjustment of auxiliary ligand. More interestingly, both complexes exhibit temperature-dependent luminescence of high sensitivity with a large fluorescence enhancement (12-fold for 1, 21-fold for 2), which can be easily recognized by the naked-eye (dramatic red-shift Δ=104 nm for 1, larger Δ=113 nm for 2 at 77 K compared to those at 298 K). The correlation between luminescent thermochromism and temperature-dependent variation of the coordination modes of template NO3 (-) anion, Ag⋅⋅⋅S and Ag⋅⋅⋅Ag distances are also elucidated through variable-temperature single-crystal X-ray crystal structure (VT-SCXRD) analyses.

“…Metal alkynyl complexes can be used as versatile precursors for the synthesis of high‐nuclearity silver clusters 8. 9 An elegant example is the novel halide‐templated rhombohedral silver–alkynyl cage compounds [Ag 14 (CC t Bu) 12 X] + (X=F, Cl, Br) reported by Vilar, Mingos and co‐workers 10. It is believed that halide ions are important for the formation of these types of silver clusters.…”
