Arylation of TeCl 4 with arylboroxine–pyridine complexes [(RBO) 3 ·C 5 H 5 N, where R = m ‐O 2 NC 6 H 4 ( 1 ), p ‐O 2 NC 6 H 4 ( 2 ), m ‐NCC 6 H 4 ( 3 ), p ‐NCC 6 H 4 ( 4 )] and advantageous moisture provided good yields of the pyridinium aryltetrachlorotellurates [C 5 H 6 N][RTeCl 4 ] [R = m ‐O 2 NC 6 H 4 ( 5 ), p ‐O 2 NC 6 H 4 ( 6 ), m ‐NCC 6 H 4 ( 7 ), p ‐NCC 6 H 4 ( 8 )]. Compounds 5 and 8 have been investigated by X‐ray crystallography. Key features of both crystal structures are intermolecular secondary TeċċċCl interactions between the aryltetrachlorotellurate anions and weak association of the cations and anions. Electrospray mass spectra of compound 5 reveal that the associative interactions also play a role in solution. Copyright © 2005 John Wiley & Sons, Ltd.
