SYNTHESIS AND CRYSTAL STRUCTURES OF DICOBALT BEXACARBONYL COMPLEXES OF DICATIONIC ALKYNE-BRIDGED IMIDAZOLIUM AND TRIAZOLIUM DERIVATES

摘要

Dicationic alkyne-bridged imidazolium and triazolium chlorides were subjected to counter-ion replacement reaction with weakly coordinating anions, such as hexafluoridophosphate and bis(trifluoromethanesulfonyl)amide. The resulting low-melting salts were further functionalized to dicobalt hexacarbonyl adducts. Seven crystal structures were determined by X-ray diffraction. Interionic C-H center dot center dot center dot F and C-H center dot center dot center dot O contacts were observed.
