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

ABSTRACT: 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.

1,1'-[(5-Hy-droxy-methyl-1,3-phenyl-ene)bis-(methyl-ene)]dipyridin-4(1H)-one monohydrate.

Project description:The asymmetric unit of the title compound, C(19)H(18)N(2)O(3), comprises a whole organic dipyridinone mol-ecule plus a water mol-ecule of crystallization. The planes of the pyridinone rings are approximately perpendicular with the plane of the central aromatic ring [dihedral angles = 80.68?(8) and 83.65?(8)°]. The C-O bond of the hy-droxy group subtends an angle of 31.71?(10)° with the plane through the central aromatic ring. The crystal packing is mediated by the presence of several O-H?O hydrogen-bonding inter-actions and while the water mol-ecules form a C(2) (1)(4) chain parallel to the c axis of the unit cell, the pendant hy-droxy groups are engaged in O-H?O=C hydrogen bonds described by a C(1) (1)(12) graph-set motif which runs parallel to the a axis.

N,N'-(2-Hy-droxy-propane-1,3-di-yl)bis-(2-hy-droxy-benzamide) monohydrate.

Project description:In the title hydrate, C17H18N2O5·H2O, the complete organic mol-ecule is generated by a crystallographic mirror plane with one C and one O atom lying on the mirror plane. The O atom of the water mol-ecule has m site symmetry. Two symmetry-related intra-molecular O-H?O hydrogen bonds complete S(6) rings in the organic mol-ecule. In the crystal, the components are linked into (010) sheets by O-H?O and N-H?O hydrogen bonds.

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

Project description: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.

Project description:In the title molecular salt, 2C(3)H(10)NO(+)·C(10)H(6)O(6)S(2) (2-), the cations and anions are associated via N-H?O and O-H?O hydrogen-bonding inter-actions, giving rise to a three-dimensional structure with zigzag rows of cations lying between rows of anions. The asymmetric unit contains one cation and one half-anion, which is related to the remainder of the mol-ecule by an inversion center.

Poly[[nona-aqua-bis-(?-5-hy-droxy-benzene-1,3-di-carboxyl-ato)(5-hy-droxy-benzene-1,3-di-carboxyl-ato)dicerium(III)] hexa-hydrate].

Project description:In the title coordination polymer, {[Ce2(C8H4O5)3(H2O)9]·6H2O} n , the asymmetric unit is formed by two Ce(III) atoms, three 5-hy-droxy-benzene-1,3-di-carboxyl-ate ligands, nine coordinating water mol-ecules and six water mol-ecules of crystallization. The two Ce(III) atoms are bridged by 5-hy-droxy-benzene-1,3-di-carboxyl-ate ligands acting in a bis-bidentate coordination mode, generating infinite chains along [101]. Both independent metal atoms are nine-coordinated, one by four O atoms from the carboxyl-ate groups of two bridging 5-hy-droxy-benzene-1,3-di-carboxyl-ate ligands and five O atoms from water mol-ecules, generating a tricapped trigonal-prismatic geometry. The coordination around the second Ce(III) atom is similar, except that one of the water mol-ecules is replaced by an O atom from an additional 5-hy-droxy-benzene-1,3-di-carboxyl-ate ligand acting in a monodentate coordination mode and forming a capped square-anti-prismatic geometry.

trans-Tetra-aqua-bis-[1,3-bis-(4-pyrid-yl)propane-κN]cobalt(II) biphenyl-4,4'-disulfonate monohydrate.

Project description:In the title compound, [Co(C(13)H(14)N(2))(2)(H(2)O)(4)](C(12)H(8)O(6)S(2))·H(2)O, the cation, anion and uncoordinated water mol-ecule have crystallographically imposed twofold symmetry. The cobalt(II) atom exhibits a slightly distorted octa-hedral coordination geometry provided by two N atoms from two 1,3-bis-(4-pyrid-yl)propane ligands and the O atoms from four water mol-ecules. The dihedral angle between the pyridine rings in the ligand is 86.14 (11)°, whereas the dihedral angle formed by the symmetry-related benzene rings in the anion is 35.81 (12)°. In the crystal, cations, anions and water mol-ecules are linked into layers parallel to the ac plane by O-H⋯O and O-H⋯N hydrogen-bond inter-actions. The layers are further connected into a three-dimensional network by C-H⋯O hydrogen bonds.

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.

Project description:The title complex, [Nd(2)(C(8)H(7)O(3))(6)(C(10)H(8)N(2))(2)(H(2)O)(2)]·H(2)O, contains two Nd atoms, six 4-hy-droxy-phenyl-acetate (hpaa) anions, two 4,4'-bipyridine mol-ecules (bipy) and two water mol-ecules; an additional water mol-ecule of solvation is also present in the crystal structure. Each of the Nd(III) ions is nine-coordinated by seven O atoms from four hpaa ligands, an N atom from a bipy ligand and an O atom from a water mol-ecule in a distorted tricapped trigonal-prismatic geometry. The hpaa ligands are coordinated to the Nd(III) ions in the bridging and bridging tridentate modes. Extensive O-H?O, O-H?N and C-H?O hydrogen bonding stabilizes the crystal structure.

Crystal structure of 1,3-bis-(3-<i>tert</i>-butyl-2-hy-droxy-5-methyl-benz-yl)-1,3-diazinan-5-ol monohydrate.

Project description:In the title hydrate, C28H42N2O3·H2O, the central 1,3-diazinan-5-ol ring adopts a chair conformation with the two benzyl substituents equatorial and the lone pairs of the N atoms axial. The dihedral angle between the aromatic rings is 19.68?(38)°. There are two intra-molecular O-H?N hydrogen bonds, each generating an S(6) ring motif. In the crystal, classical O-H?O hydrogen bonds connect the 1,3-diazinane and water mol-ecules into columns extending along the b axis. The crystal structure was refined as a two-component twin with a fractional contribution to the minor domain of 0.0922?(18).
