Bis3-(dihydroxy­boryl)anilinium sulfate

摘要

In the title compound, 2C6H9BNO2 ⁺·SO4 ²⁻, the dihydroxy­boryl group of one of the two independent boronic acid mol­ecules participates in (B)O—H⋯OB and N—H⋯OB hydrogen bonds, while the second is involved mainly in the formation of the charge-assisted heterodimeric synthon –B(OH)2⋯⁻O2SO2 ⁻. These aggregates are further connected through N—H⋯Osulfate inter­actions, forming a complex three-dimensional hydrogen-bonded network.
