✦ Synopsis
The compounds [quinolinium] 4 [Bi 2 Cl 10 ] (1), [isoquinolinium]
have been obtained by reacting bismuthate oxide and the appropriate base in HCl acid medium. The crystal structures of 1 and 2 consist of quinolinium and isoquinolinium cations, respectively, interacting through hydrogen bonding with [Bi 2 Cl 10 ] 4 -dimers. The different degree of interactions in the two derivatives causes significant differences in the bond distances of the anions. The crystal structure of 3 is made of [BiCl 6 ] 3 -and Cl -anions and 8-hydroxyquinolinium cations. Hydrogen bond interactions including the N-bonded and O-bonded H atoms together with an interstitial chlorine atom stabilize the entire crystal structure.
