(MesTe) 2 and bromine or chlorine react with pyridinium bromide and pyridinium chloride to give (PyH)[mesTeBr 2 ] ( 1 ), (PyH)[mesTeClBr] ( 2 ) and (PyH)[mesTeCl 2 ] ( 3 ), respectively. The Te II atoms in 1 , 2 and 3 adopt a three‐coordinate, T‐shaped configuration and the trans tellurium‐halogen bonds present different distances, since the X(1)‐halogens {Br ( 1 ), Cl ( 2 , 3 )} attain hydrogen bondings toward the N–H group of the pyridinium cations. The title compounds do not reproduce the dimeric assembling of some newly reported parent tellurium dihalides.
