Abstract
Abstract The compound [3,5-dibromo-2-amino-4,6-dimethylpyridinium] 2 CuCl 4 , (1) , was prepared from acidic hydrochloric acetonitrilic medium containing CuCl 2 and 3,5-dibromo-2-amino-4,6-dimethylpyridinium bromide while [3,5-dibromo-2-amino-4,6-dimethylpyridinium] 2 CuBr 4 , (2) , from acidic HBr/Br 2 ethanolic medium containing 4,6-dimethylpyridine and CuBr 2 . The ring got dibrominated at 3 and 5 positions in situ. Single-crystal X-ray diffraction proved the compounds to be isomorphous in P − 1. A systematic study of the crystallographic parameters in dibrominated and nonbrominated 2-amino-4,6-dimethylpyridine salts will explain the role of nonclassical noncovalent interaction between aryl bromine and ionic metal bromide in the control of structure.
