H-1 NMR analysis and crystal structures of 1,1',3,3'-tetramethyl-2,2'-bi-1H-imidazolium bis(tetraphenylborate): Ion-associative interactions containing ketone, aldehyde, and nitrile
The title dication interacts with ion-associable tetrapheryl-borate (BPh4) anions in an acetone or acetonitrile solution, and crystals of the salt included some kinds of ketone, aldehyde, and nitrile as guest molecules to afford unique molecular aggregations.
