3,3′-(Dodecane-1,12-diyl)bis(1-methylimidazolium) 5,5′-azotetrazolate heptahydrate

Abstract

The title compound, C20H36N4·C2N10·7H2O, was obtained by reaction of 1-methylimidazole with 1,12-dibromododecane, followed by repeated ion metathesis (bromide → sulfate → azotetrazolate). An intricate network of hydrogen bonds is formed between anions and water molecules, leading to a layered arrangement parallel to (101).
