Crystal engineering: the effects of π–π interactions in copper(i) and silver(i) complexes of 2,7-diazapyrene

Abstract

The ligand 2,7-diazapyrene (L) is used to construct three- and two-dimensional arrays with Cu^I and Ag^I ions: {[Cu^IL₂]PF₆}_∞ shows an adamantoid network with three interpenetrating networks, while {[Ag^IL₂(MeCN)₂]BF₄} _∞ forms linear chains of [AgL]_∞ units linked by apparent π–π stacking and Ag···Ag interactions between adjacent diazapyrene ligands to form two-dimensional sheets.
