Diverse Ag(i) complexes constructed from asymmetric pyridyl and pyrimidyl amide ligands: roles of Ag⋯Ag and π–π interactions
All nine complexes adopt discrete structures with 1 being tetranuclear and 2–9 being mononuclear. Moreover, Ag⋯Ag short contacts, π⋯π stacking interactions and/or Ag⋯O interactions are found in these complexes which extend the dimensionalities of the structures. The changes of the donor atom positions and counteranions significantly affect the supramolecular structures of these complexes and the L1–L4
