Molar-ratio-dependent supramolecular isomerism: Ag(I) coordination polymers with bis(cyanobenzyl)sulfides.

The ratio is the key: On varying the molar ratio of the reactants, AgNO3 and tridentate m-L ligand, supramolecular isomers 1 and 2 comprising a 2D polymeric network were obtained. Conformational differences of m-L play a crucial role in the 2D network structures adopted for isomers 1 and 2.
