Crystal Structure of a Methanesulfonate Salt of 4-(N-Methyl)pyridinium Boronic Acid

Abstract

The structure of a methanesulfonate salt of 4-(N-methyl)pyridinium boronic acid, [4-(N-Me)PyB(OH)₂]CH₃SO₃·H₂O, was determined by X-ray crystallography, and was characterized as: P1, a = 5.6937(16), b = 7.805(2), c = 13.522(3)Å, α = 99.46(3), β = 91.45(3), γ = 108.014(17)°, Z = 2, V = 561.8(2)ų. In the crystals, the cation and the anion are linked by BOH…O(anion), BOH…O(water), and (water)OH…O(anion) hydrogen bonds to stabilize the 1:1:1-cation:anion:water salt unit.
