Title: Be[B2(SO4)4] – A Borosulfate Exhibiting Ino‐ and Phyllosilicate Analogue Topology.
Authors: Sutorius, Stefan; Hanrath, Michael; Bruns, Jörn
Abstract: Borosulfates are a constantly expanding class of silicate analogue compounds. The anionic substructures are composed of vertex‐connected (BO4)‐ and (SO4)‐tetrahedra and feature topologies of monomeric, oligomeric, and polymeric anions. The latter resemble typical motifs of ino‐, phyllo‐ and tectosilicates but none of the hitherto known borosulfates exhibits two different anion topologies within one structure. However, this is very rare even for the homopolyanionic silicates. Be[B2(SO4)4] is the first borosulfate featuring anionic chains and layers within one structure and both substructures are interconnected by (BeO4)‐tetrahedra. DFT calculations complement the experimental studies and help to describe the bonding situation of the Be−O bonds.
