Hexaaqua-zinc(II) dipicrate.

ABSTRACT: In the title compound, [Zn(H(2)O)(6)](C(6)H(2)N(3)O(7))(2), the Zn(II) ion is located on an inversion center and is coordinated by six water mol-ecules in an octa-hedral geometry. The picrate anions have no coordination inter-actions with the Zn(II) atom. The three nitro groups are twisted away from the attached benzene ring by19.8?(3), 6.5?(4) and 28.6?(3)°. There are numerous O-H?O hydrogen bonds in the crystal structure.

Project description:In the crystal structure of the title compound, [Zn(H(2)O)(6)](C(6)H(5)O(4)S)(2)·2H(2)O, the Zn(II) atom lies on a center of inversion. The complex cation inter-acts with the anion and uncoord-inated water mol-ecules by O-H?O hydrogen bonds, generating a three-dimensional network. The anion is disordered over two equal positions along the hydr-oxy-sulfonate C-C axis.

Hexaaqua-zinc(II) dichloride bis-(hexa-methyl-enetetramine) tetra-hydrate.

Project description:The title compound, [Zn(H(2)O)(6)]Cl(2)·2C(6)H(12)N(4)·4H(2)O, has been prepared under mild hydro-thermal conditions. The Zn(II) atom, located on a centre of symmetry, is coordinated by six water mol-ecules in a distorted octa-hedral coordination geometry. The hexa-methyl-enetetra-mine mol-ecule is not coordinated to Zn(II) but links the Zn complexes via three O-H?N hydrogen bonds. The remaining N atom of the hexa-methyl-enetetra-mine mol-ecule is hydrogen-bonded to a solvent water mol-ecule. In the crystal structure, inter-molecular O-H?O, O-H?N and O-H?Cl hydrogen bonds link the components into a three-dimensional network.

Hexaaqua-zinc(II) bis-[4-(2-hydroxy-benzyl-ideneamino)benzene-sulfonate].

Project description:In the title compound, [Zn(H(2)O)(6)](C(13)H(10)NO(4)S)(2), a distorted ZnO(6) octa-hedron results from the coordination by the six water mol-ecules. Only three of the water molecules are crystallographically unique, as the Zn atom lies on an inversion center. The Zn-O bond lengths are in the range 2.054?(4)-2.073?(4)?Å. A network of hydrogen bonds helps to establish the crystal packing.

Hexaaqua-zinc(II) bis-[tris-(3-carb-oxy-pyridine-2-carboxyl-ato)zincate(II)].

Project description:The title compound, [Zn(H(2)O)(6)][Zn(C(7)H(4)NO(4))(3)](2), consists of two [Zn(py-2,3-dcH)(3)](-) anions (py-2,3-dcH is 3-carboxy-pyridine-2-carboxylate) and one [Zn(H(2)O)(6)](2+) cation. The anion is a six-coordinate complex located on a threefold rotation axis with a slightly distorted octa-hedral geometry around Zn(2+) ion. The cation is also six-coordinate with an octa-hedral geometry around the Zn atom, located at a axis. Non-covalent inter-actions such as ?-? stacking [centroid-centroid distance = 3.828?(4)Å] and O-H?O hydrogen bonds play important roles in stabilizing the supra-molecular structure.

Project description:The asymmetric unit of the title hydrated mol-ecular salt, [Zn(H(2)O)(6)](C(6)H(5)O(4)S)(2)·2H(2)O, contains two half-cations, two anions and two uncoordinated water mol-ecules. Both cations are completed by crystallographic inversion symmetry, generating almost regular ZnO(6) octa-hedra. In the crystal, the cations, anions and uncoordinated water mol-ecules are linked by O-H?O hydrogen bonds, forming a three-dimensional network.
