摘要

The structures of two hydrated salts of 4-amino-phenyl-arsonic acid (p-arsanilic acid), namely ammonium 4-amino-phenyl-arsonate monohydrate, NH4 +·C6H7AsNO3 -·H2O, (I), and the one-dimensional coordination polymer catena-poly[[(4-amino-phenyl-arsonato- κO)di-aqua-sodium]-μ-aqua], [Na(C6H7AsNO3)(H2O)3] n , (II), have been determined. In the structure of the ammonium salt, (I), the ammonium cations, arsonate anions and water mol-ecules inter-act through inter-species N - H?O and arsonate and water O - H?O hydrogen bonds, giving the common two-dimensional layers lying parallel to (010). These layers are extended into three dimensions through bridging hydrogen-bonding inter-actions involving the para-amine group acting both as a donor and an acceptor. In the structure of the sodium salt, (II), the Na+ cation is coordinated by five O-atom donors, one from a single monodentate arsonate ligand, two from monodentate water mol-ecules and two from bridging water mol-ecules, giving a very distorted square-pyramidal coordination environment. The water bridges generate one-dimensional chains extending along c and extensive interchain O - H?O and N - H?O hydrogen-bonding inter-actions link these chains, giving an overall three-dimensional structure. The two structures reported here are the first reported examples of salts of p-arsanilic acid.
