Figure 10From: Design of co-crystals/salts of some Nitrogenous bases and some derivatives of thiophene carboxylic acids through a combination of hydrogen and halogen bonds(a) Formation of ladder through O–H…N and Cl…O bonds in (8b) where 4-4bipy acts as rungs and 5-tpc as uprights. (b) The three molecule aggregates in 8b are further linked to similar neighboring aggregates through strong Cl…O interactions.Back to article page
