Full NMR and ESI-MS spectra, and differential scanning calorimeter data are presented for 15 substitutedphenylarsonicacids, including two new fluoro-substituted examples. X-ray crystal structure determinations of five examples (phenylarsonicacid 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
Barriers to pseudorotation in AsV species, in which a five-membered ring is constrained to span the equatorial positions in the trigonal bipyramidal intermediates, are in the range of 20–23 kcal mol–1, and thus are comparable with the corresponding barriers in PV systems with similar structures.
As V物种伪旋转的障碍(其中一个五元环被约束跨越三角双锥体中间体中的赤道位置)的范围在20-23 kcal mol –1范围内,因此可与P V系统的相似的结构。
