title: Beyond classical coordination: silver-pi interactions in metal dipyrrin complexes.
abstract: Homo- and hetero-leptic Zn and Cu complexes of dipyrrin type ligands bearing mono- and di-cyanophenyl groups when combined with silver cations lead to the formation of Ag(I)-C=C double bond interactions unprecedented in the crystalline phase.
