A synthesis to control the amount of reacting SO 3 and the cation to boron ratio during solvothermal syntheses with oleum is crucial to explore the structural diversity of borosulfates. The novel borosulfate Sr[B 3 O(SO 4 ) 4 (HSO 4 )] was synthesized in phase‐pure form, and the anionic substructure features a triple‐vertex connection of three (BO 4 ) tetrahedra via one oxygen atom. The motif was previously unknown for borosulfates, but is not uncommon for borates. This outperformance of silicate‐untypical behavior of a borosulfate was further investigated by means of DFT calculations, as reported by Jörn Bruns and co‐workers in their Communication on page 19740.
