In the title compound, 2C(8)H(9)BrO(2)·H(2)O, the O-C-C-C torsion angles for the hy-droxy-ethyl group and the Br-C-C-O torsion angles involving bromo and phenol groups are 61.7 (11) and 0.7 (12)°, respectively, in one independent mol-ecule and 61.5 (11) and 0.2 (11)°, respectively, in the other. In the crystal, mol-ecules are linked through O-H⋯O and O-H⋯Br hydrogen bonds, forming a polymeric c...

In the crystal structure of the title salt, [Ag(NH(3))(2)](4)(C(7)H(6)O(7)S(2))(2)·H(2)O, the four independent Ag(I) complex cations all lie on special positions of m site symmetry, as do the two independent 2-hy-droxy-5-methyl-benzene-1,3-disulfonate anions. The Ag(I) cations exist in an almost linear coordination geometry [N-Ag-N = 175.2 (2), 178.08 (16), 175.8 (2) and 178.20 (19)°]. The wate...

The title compound, (C(11)H(14)N(4)O(4))[SbCl(4)]·H(2)O, comprises a protonated doxofyllinium cation [7-(1,3-dioxolan-2-ylmeth-yl)-1,3-dimethyl-2,6-dioxo-3,7-dihydro-1H-purin-9-ium], an [SbCl(4)](-) anion and a water mol-ecule linked by N-H⋯O and O-H⋯Cl hydrogen bonds: the [SbCl(4)](-) anions form centrosymmetric dimers via weak Sb⋯Cl inter-actions [Sb⋯Cl = 3.1159 (9) Å]. The geometrical arrang...

The title compound, C(10)H(8)N(4)O(4)·H(2)O, was obtained by the reaction of 5-hy-droxy-2-nitro-benzaldehyde with cyano-acetohydrazide in methanol. The non-H atoms of the hydrazone molecule are approximately coplanar, with a mean deviation from the least-squares plane of 0.056 Å. In the crystal, mol-ecules are linked by N-H⋯O, O-H⋯N and O-H⋯O hydrogen bonds, generating a three-dimensional network.
