In the crystal structure of the title compound, C16H10N2O8·2H2O, the organic mol­ecule is located on a centre of symmetry. The two benzene rings are parallel, but not coplanar, as indicated by N=N—C—C torsion angles involving the azo group of 12.1 (5) and −168.2 (3)°. The organic mol­ecule and the water mol­ecule are linked by O—H⋯O hydrogen bonds, forming a three-dimensional network.

Comment top

In an attempt to prepare a Cd-containing coordination polmyer (Carlucci et al., 2000), the title compound was obtained as an unexpected product.

The complete organic molecule (Fig. 1) is generated by inversion at the midpoint of the central N—N bond and a water molecule of crystallization completes the crystal structure. The components interact through O—H···O hydrogen bonds (Table 1) to generate a three-dimensional architecture.

Experimental top

CdSO4 (0.033 g, 0.012 mmol), 2,2',3,3'-diazenediyldiphthalic acid (0.026 g, 0.014 mmol) and NaOH (0.048 mmol, 0.12 mmol), were added in a mixed solvent of acetonitrile and the mixture was heated for ten hours under reflux. During the process stirring and influx were required. The resultant was then filtered to give a pure solution which was infiltrated by diethyl ether freely in a closed vessel. Single crystals suitable for X-ray diffraction were obtained for a week.

Refinement top

C-bound H atoms were placed at calculated positions (C—H = 0.93 Å) and were treated as riding, with Uiso(H) = 1.2Ueq(C). Carboxy H atoms were constrained with O—H = 0.82 Å and Uiso(H) = 1.2Ueq(O), but each O—H group was allowed to rotate freely about its C—O bond. Water H atoms were tentatively located in a difference Fourier map and were refined, with distance restraints of O–H = 0.85 (1) Å and H···H = 1.39 (1) Å, and with Uiso(H) = 1.2Ueq(O). The maximum residual peak is located 1.34 Å from Br1.

Special details top

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.
