B₂S₂O₉ – ein Borsulfat mit Phyllosilicat‐Topologie

Abstract

So viele Tetraeder: Die Kondensation von [BO4]‐ (orange) und [SO4]‐Tetraedern (gelb) in dem ersten binären Borsulfat B2S2O9 führt zu einer Struktur mit einer typischen Phyllosilicat‐Topologie. Die Verbindung wurde durch Hydrolyse von HSO3Cl mit B(OH)3 erhalten.

Synthesis and Characterization of the First Lead(II) Borosulfate Pb[B2(SO4)4]

“…The dimensionalities of the anionic substructures range from separated complex anions over chains and layers to extended 3D networks and, hitherto, the properties of the borosulfates are mostly discussed in this context. For example, layer‐like borosulfates might act as material for intercalation of neutral or ionic species, depending on the charge of the anionic substructure , . Recently, we contributed for the first time DFT calculations to predict p K a values for protonated borosulfates …”

Further New Borosulfates: Synthesis, Crystal Structure, and Vibrational Spectra of A[B(SO4)2] (A = Na, K, NH4) and the Crystal Structures of Li5[B(SO4)4] and NH4[B(S2O7)2]

“…To obtain B–O–B bridges, i.e. the connection of BO 4 tetrahedra, it seems to be necessary to reduce the B:S ratio below 1:2 as done for B 2 S 2 O 9 5 that adopts a layer structure with phyllosilicate topology. Independent from the B:S ratio there are two aspects which enable different topologies.…”
