A Double-Decker Silver(I) Coordination Polymer of 1-Methylpyrene with Columnar Aromatic Stacks. Effect of Substituting Groups on Structure of Silver(I) Complexes with Polycyclic Aromatic Hydrocarbons

Abstract

A novel silver(I) coordination polymer of 1-methylpyrene (mpyr) with double-decker motifs, {[Ag2(mpyr)2(ClO4)2]0.5benzene}n (1), was synthesized and characterized. Polymer 1 consists of 1-D double-decker chains, which are formed by dimeric double-decker units ([Ag(mpyr)(ClO4)]2) through the linkage of the perchlorate groups. In addition, the dimeric moieties between the adjacent chains are stacked to lead to column π−π stacks. Therefore, complex 1 can also be regarded as a 2-D stacking polymer. The effects of substituting groups, and other factors, on the structure of silver(I) complexes with polycyclic aromatic hydrocarbons are also discussed.
