Hitherto, the structural diversity of transition metal borosulfates has been limited to B−O−S and B−O−B bridges. Ag[B(S 2 O 7 ) 2 ] represents the very first transition metal borosulfate featuring S−O−S bridges. The compound was synthesized solvothermally in oleum (65 % SO 3 ) and crystallizes in a new structure type in P 2 1 / c (no. 14) with Z =4, a =950.7(4) pm, b =960.1(4) pm, c =1173.0(4) pm and β =98.350(11)°. The crystal structure comprises complex anions [B(S 2 O 7 ) 2 ] − – consisting of a central boron atom and two chelating disulfate groups – and charge balancing Ag + ions. Vibrational spectroscopy confirms the presence of S−O−S bridges. A thermal decomposition from Ag[B(S 2 O 7 ) 2 ] towards Ag[B(SO 4 ) 2 ] was monitored by means of thermogravimetric analysis (TGA) and temperature programmed X‐ray diffraction (TPXRD).
