Disodium 4,5,6-trihy-droxy-benzene-1,3-disulfonate dihydrate.

ABSTRACT: In the title compound, 2Na(+)·C(6)H(4)O(9)S(2) (2-)·2H(2)O, the benzene rings of the 4,5,6-trihy-droxy-benzene-1,3-disulfonate ions, which are stacked parallel to each other forming rods parallel to the a axis, are slightly deformed (planarity, symmetry) mainly because of the high degree of substitution. The two sodium ions, located within pockets of the anion rods, are coordinated by six and seven O atoms, resulting in octa-hedral and penta-gonal-bipyramidal coordinations, respectively. In addition to these coordinative bonds towards sodium, an extended network of intra- and inter-molecular hydrogen bonds occurs.

Tetra-kis[diamminesilver(I)] bis-(2-hy-droxy-5-methyl-benzene-1,3-disulfonate) monohydrate.

Project description: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 water mol-ecule is disordered about a mirror plane. Two independent complex cations are linked by an Ag?Ag inter-action of 3.3151?(1)?Å, furnishing a linear [Ag(NH(3))(2)](n) polycationic chain running along b. The free complex cations, polycationic chain and 2-hy-droxy-5-methyl-benzene-1,3-disulfonate anions inter-act via N-H?O and O-H?O hydrogen bonds, forming a three-dimensional network.

(E)-N'-(2,3,4-Trihy-droxy-benzyl-idene)-isonicotinohydrazide dihydrate.

Project description:In the title isoniazid derivative, C(13)H(11)N(3)O(4)·2H(2)O, the Schiff base mol-ecule exists in an E configuration with respect to the acyclic C=N bond. An intra-molecular O-H?N hydrogen bond forms a six-membered ring, producing an S(6) ring motif. The essentially planar pyridine ring [maximum deviation = 0.0119?(8)?Å] is inclined at a dihedral angle of 7.30?(4)° with respect to the benzene ring. In the crystal, inter-molecular O-H?N, O-H?O, N-H?O and C-H?O hydrogen bonds link the mol-ecules into two-dimensional arrays lying parallel to the (10) plane. These arrays are further inter-connected into a three-dimensional extended network via O-H?O and C-H?O hydrogen bonds. A weak inter-molecular ?-? inter-action [centroid-to-centroid distance = 3.5627?(5)?Å] is also observed.

Bis(dimethyl-ammonium) 2,5-dihy-droxy-benzene-1,4-disulfonate.

Project description:In the crystal of the title salt, 2C(2)H(8)N(+)·C(6)H(4)O(8)S(2) (2-), the anion lies on a center of inversion. The dimethyl-ammonium cation forms one N-H?O hydrogen bond and another bifurcated N-H?O hydrogen bond. The hy-droxy group links with the sulfonyl group via an inter-molecular O-H?O hydrogen bond. These N-H?O and O-H?O hydrogen bonds generate a three-dimensional network.

(E)-1-(2,4,6-Trihy-droxy-benzyl-idene)-4-ethyl-thio-semicarbazide dihydrate.

Project description:In the title mol-ecule, C(10)H(13)N(3)O(3)S·2H(2)O, the thio-semi-carbazide =N-NH-C(=S)-NH- fragment [torsion angle = 0.2 (1)°] is nearly coplanar with the benzene ring [dihedral angle = 2.4 (1)°]. The benzene ring and semicarbazide moiety are located on opposite sites of the C=N bond, showing an E configuration. The hy-droxy, imino and water H atoms are engaged in extensive hydrogen bonding, forming a three-dimensional network.

Project description:The crystal studied of the title compound, C(7)H(9)N(2)O(4) (+)·ClO(4) (-)·C(7)H(8)N(2)O(4)·H(2)O, was found to be a racemic twin with a 0.72 (18):0.28 (18) domain ratio.
