The crystal structures of 2-hy­droxy-5-[(E)-(4-nitro­phen­yl)diazen­yl]benzoic acid, C13H9N3O5, (I), ammonium 2-hy­droxy-5-[(E)-phenyl­diazen­yl]benzoate, NH4+·C13H9N2O3, (II), and sodium 2-hy­droxy-5-[(E)-(4-nitro­phen­yl)diazen­yl]benzoate trihydrate, Na+·C13H8N3O5·3H2O, (III), have been determined using single-crystal X-ray diffraction. In (I) and (III), the phenyl­diazenyl and carb­oxy­lic acid/carboxyl­ate groups are in an anti orientation with respect to each other, which is in accord with the results of density functional theory (DFT) calculations, whereas in (II), the anion adopts a syn conformation. In (I), mol­ecules form slanted stacks along the [100] direction. In (II), anions form bilayers parallel to (010), the inner part of the bilayers being formed by the benzene rings, with the –OH and –COO substituents on the bilayer surface. The NH4+ cations in (II) are located between the bilayers and are engaged in numerous N—H...O hydrogen bonds. In (III), anions form layers parallel to (001). Both Na+ cations have a distorted octa­hedral environment, with four octa­hedra edge-shared by bridging water O atoms, forming [Na4(H2O)12]4+ units.

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes.

Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger. The C-bound H atoms were placed in idealized positions, with constrained distances of 0.93 Å and with Uiso(H) = 1.2Ueq(C). Phenol and carboxylic H atoms were restrained so that to reproduce the C—O—H angle values observed in salicylic acid (neutron structure determination, Bacon et al., 1973): 107° for phenol and 109° for COOH group.

Special details top

Geometry. All s.u.'s (except the s.u. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell s.u.'s are taken into account individually in the estimation of s.u.'s in distances, angles and torsion angles; correlations between s.u.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell s.u.'s is used for estimating s.u.'s involving l.s. planes.

Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger. The C-bound H atoms were placed in idealized positions, with constrained distances of 0.93 Å and with Uiso(H) = 1.2Ueq(C). Phenol H atoms were restrained so that to reproduce the C—O—H angle value of 107° observed in salicylic acid (neutron structure determination, Bacon et al., 1973). For all water molecules, the O—H distances and H—O—H angles of 106° were restrained.
