Abstract

The reaction of 1:1 mixture of 1,3-bis(1-imidazolyl)propane and 1,4-bis(chloromethyl)durene gives a new tetracationic heterophane (2), which forms a 1:1 inclusion complex with halides and oxoanions in DMSO-d6 in the order of HSO4- > Br- > H2PO4- > Cl- > I- > ClO4- depending on the size of anions.
