Aj. Blake et al., CRYSTAL ENGINEERING - THE EFFECTS OF PI-PI INTERACTIONS IN COPPER(I) AND SILVER(I) COMPLEXES OF 2,7-DIAZAPYRENE, Chemical communications, (15), 1997, pp. 1339-1340
The ligand 2,7-diazapyrene (L) is used to construct three- and two-dim
ensional arrays with Cu-I and Ag-I ions: {[(CuL2)-L-I]PF6}(infinity) s
hows an adamantoid network with three interpenetrating networks, while
{[(AgL2)-L-I(MeCN)(2)]BF4}(infinity) forms linear chains of [AgL](inf
inity) units linked by apparent pi-pi stacking and Ag ... Ag interacti
ons between adjacent diazapyrene ligands to form two-dimensional sheet
