title: Binding of ammonium hexafluorophosphate and cation-induced isolation of unusual conformers of a hexapodal receptor.
abstract: The pyrazole-based hexa-host receptor showed the preference of an unusual conformation via 1:1 hydrogen bonding with ammonium hexafluorophosphate over steric gearing. Two different unusual conformers of the receptor are also isolated upon complexation with Cu(2+) and Cd(2+) ions.
