Abstract
Abstract 1,2,4,5-Tetrakis(dimethylamino)benzene ( 1 ) forms diprotonated salts like the bis(tetrafluoroborate) 3 and the dibromide 4 . For 4 -dihydrate an -X-ray structure revealed the presence of ‘bifurcated hydrogen bonds’. 1 and the protonated species derived therefrom are discussed with regard to the sterical requirements of ‘proton sponges’.
