Anion Control of the Self-Assembly of 2,3-Diarylpyrazines with Silver(I) Salts
The synthesis and characterization of three one-dimensional coordination polymers formed on self-assembly of 2,3-diarylpyrazines with silver(I) salts are presented. A linear double-stranded coordination polymer was formed on self-assembly of 2,3-bis(3‘5‘-dimethylphenyl)pyrazine with silver(I) tetrafluoroborate. An essentially linear double-strand coordination polymer was formed on self-assembly of 2,3-bis(3‘5‘-dimethylphenyl)pyrazine with silver(I) trifluoromethanesulfonate. In contrast a helical silver-pyrazine coordination polymer with extensive intrastrand π-stacking was formed on self-assembly of 2,3-diphenylpyrazine with silver(I) trifluoroacetate.
