Halogen bonding-assisted formation of one-dimensional polybromide–bromotellurate (2-ClPyH)<inf>2</inf>{[TeBr<inf>6</inf>](Br<inf>2</inf>)}

In the structure, mononuclear [TeBr6]2− units are connected by {Br2} linkers into 1D zigzag-shaped infinite chains. Energies of halogen bonding were estimated by theoretical methods (1.3–3.3 kcal/mol)
