Substituted phenylarsonic acids; structures and spectroscopy

Full NMR and ESI-MS spectra, and differential scanning calorimeter data are presented for 15 substituted phenylarsonic acids, including two new fluoro-substituted examples. X-ray crystal structure determinations of five examples (phenylarsonic acid and the 4-fluoro-, 4-fluoro-3-nitro-, 3-amino-4-hydroxy- and 3-amino-4-methoxy-substituted derivatives) were determined and the H-bonding crystal-packing patterns analysed.

Graphical abstractSpectroscopic data for 15 substituted phenylarsonic acids are reported, together with the X-ray structures of five examples which form extensive H-bonded networks in the crystals.Figure optionsDownload full-size imageDownload as PowerPoint slide
