CRYSTAL STRUCTURES OF POLYBROMIDE SALTS OF BIS(PYRIDYL)ALKANE DICATIONS
Reactions of solutions of 1,1′-(alkane-1, х -diyl)-bis(pyridinium) dibromides ((PyC x )Br 2 ) with 1M Br 2 in HBr result in the formation of tribromides (PyC x )(Br 3 ) 2 ( x = 3 ( 1 ), 4 ( 2 ), 5 ( 3 )) and pentabromide (PyC 6 )(Br 5 ) 2 ( 4 ). Their structures are investigated by X-ray crystallog...
