The reaction of Ag(NO₃) with H₃BO₃ in oleum (20 % SO₃) yielded single crystals of Ag[B(SO₄)₂] [tetragonal, P4/ncc, Z = 4, a = 8.6679(5) Å, c = 7.2897(5) Å, V = 547.69(7) ų]. In Ag[B(SO₄)₂], infinite anionic chains, according to the Niggli formula _∞¹[B(SO₄)_4/2]^–, are found in tetragonal-rod packing with charge compensation by Ag^I cations. The chains are built by central boron atoms coordinated through oxygen atoms to four bidentate bridging SO₄ tetrahedra. Terminal oxygen atoms of the SO₄ tetrahedra coordinate to the silver cations in the form of slightly distorted square prisms. Magnetochemical investigations reveal the expected closed-shell behavior of d¹⁰ cations. DFT investigations of the solid-state structure corroborate the experimental findings and permit the assignment of vibrational spectroscopic data.
