Abstract Recently we reported the synthesis and characterization of Bi(H 3 O)[B(SO 4 ) 2 ] 4 , at that time representing only the second tectosilicate analogous borosulfate. Inspired by this structure type, we herein present the first modular system within borosulfate chemistry. M III M I [B(SO 4 ) 2 ] 4 (M III =Bi 3+ , Sb 3+ , Lu 3+ ; M I =H 3 O + , NO 2 + , Li + , Na + , K + , Rb + , Cs + ) were synthesised under solvothermal conditions and show a large variability towards their mono‐ and trivalent cation while retaining the same three‐dimensional anionic network. Based on their combination, the titled compounds crystallize in the tetragonal space groups I (no. 82), P (no. 81) and the monoclinic space group C 2 (no. 5) all connected via group‐subgroup relations. Our initial characterization includes single‐crystal as well as powder X‐ray diffraction, vibrational spectroscopy and thermal analysis of the new compounds.
