Wells–Dawson anions covalently suspended up and down this chain. The steric hindrance of –CH3 groups in H2bdpm leads to the formation of mono-nuclear AgI subunits in 2–4. The influence of –CH3 steric hindrance in bis(pyrazolyl) ligands on the structures of 1–4 is discussed. The electrochemical and photocatalytic properties of the title compounds have been studied.
