ABSTRACT
The coordination polymers [Ag4 (O2 CCF3 )4 (phen)3 ]â
phenâ
arene (1â
phenâ
arene) (phen=phenazine; arene=toluene, p-xylene or benzene) have been synthesised from the solution phase in a series of arene solvents and crystallographically characterised. By contrast, analogous syntheses from o-xylene and m-xylene as the solvent yield the solvent-free coordination polymer [Ag4 (O2 CCF3 )4 (phen)2 ] (2). Toluene, p-xylene and benzene have been successfully used in mixed-arene syntheses to template the formation of coordination polymers 1â
phenâ
arene, which incorporate o- or m-xylene. The selectivity of 1â
phenâ
arene for the arene guests was determined, through pairwise competition experiments, to be p-xylene>toluene≈benzene>o-xylene>m-xylene. The largest selectivity coefficient was determined as 14.2 for p-xylenem-xylene and the smallest was 1.0 for toluenebenzene.
