文摘

The compounds [quinolinium]₄[Bi₂Cl₁₀] (1), [isoquinolinium]₄[Bi₂Cl₁₀]^.2H₂O (2) and [8-hydroxyquinolinium]₄[BiCl₆]·Cl·2H₂O (3) 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 [Bi₂Cl₁₀]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 [BiCl₆]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.
