1lambda(4),4lambda(4),8lambda(4),11lambda(4)-Tetrathiacyclotetradecane-1,4,7,10-tetraylidenetetraaminium tetrakis(2,4,6-trimethylbenzenesulfonate).

Investigations of the reactivity of the thio-crown [14]aneS(4) (1,4,8,11-tetrathiacyclotetradecane) towards the aminating agent o-mesitylsulfonylhydroxylamine have lead to the crystallization of 1lambda(4),4lambda(4),8lambda(4),11lambda(4)-tetrathiacyclotetradecane-1,4,7,10-tetraylidenetetraaminium tetrakis(2,4,6-trimethylbenzenesulfonate), C10H28N4S(4)4+.4C9H11O3S-. The compound crystallizes in a centrosymmetric space group, with half a formula unit in the asymmetric unit. All S atoms within the cationic component are aminated, with the four NH(2) substituents arranged in pairs on neighbouring S atoms on opposite faces of the crown. The macrocyclic cation in the compound forms hydrogen bonds with the 2,4,6-trimethylbenzenesulfonate anions to create chains, which are further linked into thick two-dimensional sheets.
