Fig. 1: Synthetic strategy and crystal structure of 1Ag.

a Self-Assembly of 1Ag by the combination of BPND ligand, [Ag(CN)2]− and FeII ions. b and c Top and side view of the 2D layered structure for 1Ag. d, e Supramolecular π-π stacking and C-Cl···O XB interactions in 1Ag at 100 K. The red dashed lines represent supramolecular π-π stacking and C-Cl···O XB interactions. Hydrogen atoms and solvent molecules are omitted for clarity.
