Understanding halogen bonding and halogen…halogen interactions is important to employ these interactions as effective synthons in crystal engineering design strategies. A recent unusual phenomenon of modularity in crystal structures in 3,4,5-trichlorophenol example illustrates that synthons can be transferred in a modular way so that such modules are connected by halogen bonding. Halogen bonding is important from the crystal engineering perspective as it can be helpful in determin ing and predicting crystal structures.
