We synthesized melemium hydrogensulfate H 3 C 6 N 7 (NH 2 ) 3 (HSO 4 ) 3 by reaction of melem with 70 % sulfuric acid. The crystal structure was elucidated by single‐crystal XRD ( P 2 1 / n (no. 14), Z = 4, a = 10.277(2), b = 14.921(3), c = 11.771(2) Å, β = 99.24(3)°, V = 1781.5(6) Å 3 ). H 3 C 6 N 7 (NH 2 ) 3 (HSO 4 ) 3 is the first compound displaying a triple protonation of melem., In this contribution an overview of accessible melemium sulfates depending on the concentration of sulfuric acid is given. Two additional melemium sulfates were identified this way.
