Dipotassium zinc tetra-iodate(V) dihydrate.

ABSTRACT: The title compound, K(2)Zn(IO(3))(4)·2H(2)O, contains two symmetry-independent K and I atoms. These atoms, as well as the Zn atom, are coordinated by shared O atoms and, moreover, the Zn atom is coordinated by two water mol-ecules in trans positions. The K, Zn and water O atoms atoms are situated in special positions on twofold symmetry axes. The hydrogen atoms are involved in strong O-H?O hydrogen bonds and O-H?I inter-actions also occur. The crystals of the title compound are, in general, twinned, but the sample used for this experiment was free of twinning.

The triclinic form of dipotassium cobalt(II) bis-(dihydrogendiphosphate) dihydrate.

Project description:In the title compound, K(2)Co(H(2)P(2)O(7))(2)·2H(2)O, the octa-hedrally coordinated Co(2+) ion lies on an inversion centre. Two bidentate dihydrogendiphosphate anions form the equatorial plane of the [CoO(6)] octa-hedron which is completed by two water mol-ecules in axial positions. This results in isolated {Co(H(2)O)(2)[H(2)P(2)O(7)](2)}(4-) entities linked into a three-dimensional network through K-O bonds and O-H?O hydrogen-bonding inter-actions involving the dihydrogendiphosphate anions and water mol-ecules. The dihydrogendiphosphate anion, (H(2)P(2)O(7))(2-), is bent and shows an almost eclipsed conformation.

Project description:In the title compound, [Zn(C(6)H(3)FNO(2))(2)(H(2)O)(4)]·2H(2)O, the Zn(II) atom is octa-hedrally coordinated in a ZnO(4)N(2) environment by two 3-fluoro-pyridine-4-carboxyl-ate (3-fpy4-cbx) ligands and four water mol-ecules.

trans-Diaqua-bis-[5-(pyridine-3-carboxamido)-tetra-zolido-?(2)O,N(1)]zinc dihydrate.

Project description:The title compound, [Zn(C(7)H(5)N(6)O)(2)(H(2)O)(2)]·2H(2)O, consists of one Zn(II) ion located on the crystallographic inversion centre, two 5-(pyridine-3-carboxamido)-tetra-zolide ligands, two coordinated water mol-ecules and two free water mol-ecules. The Zn(II) ion adopts a slightly distorted octa-hedral coordination geometry formed by the N,O-chelating ligands and two O water atoms. The pyridine N atoms are not coordinated. In the crystal, complex mol-ecules are connected by N-H?O, O-H?N and O-H?O hydrogen bonds, forming a three-dimensional network.

Poly[diaqua-tetra-μ-seleno-cyanato-cadmium(II)dipotassium(I)].

Project description:In the title compound, [CdK(2)(NCSe)(4)(H(2)O)(2)](n), the cadmium(II) cation is situated on a twofold rotation axis and is coordinated in a slightly distorted tetra-hedral geometry by two symmetry-related μ-1,1,1,3 and two-symmetry related μ-1,1,3,3 bridging seleno-cyanate anions, all of which are Se bonded. These bridging seleno-cyanate anions are further coordinated to two symmetry-related potassium ions. Each of the potassium ions is coordinated by one terminally bonded water mol-ecule and six seleno-cyanate anions, two of which are crystallographically independent. The asymmetric unit consists of one cadmium and one potassium cation, two bridging seleno-cyanate anions and one water mol-ecule. The polymeric subunits are further connected via the seleno-cyanate anions into a three-dimensional coordination network. In this coordination network, intramolecular hydrogen bonds between neighbouring water molecules can be found.

Tetra-aqua-{1-[(1H-1,2,3-benzotriazol-1-yl)meth-yl]-1H-1,2,4-triazole}sulfato-zinc(II) dihydrate.

Project description:In the title complex, [Zn(SO(4))(C(9)H(8)N(6))(H(2)O)(4)]·2H(2)O, the Zn(II) ion is six-coordinated by one N atom from a 1-[(1H-1,2,3-benzotriazol-1-yl)meth-yl]-1H-1,2,4-triazole ligand and five O atoms from one monodentate sulfate anion and four water mol-ecules in a distorted octa-hedral geometry. The sulfate tetra-hedron is rotationally disordered over two positions in a 0.618 (19):0.382 (19) ratio. In the crystal, adjacent mol-ecules are linked through O-H⋯O and O-H⋯N hydrogen bonds involving the cation, the anion, and the coordinated and uncoordinated water mol-ecules into a three-dimensional network.

Tetra-methyl-ammonium hemi(terephthalate) dihydrate.

Project description:In the title compound, (CH(3))(4)N(+)·0.5C(8)H(4)O(4) (2-)·2H(2)O, the complete terephthalate dianion is completed by twofold symmetry and has a dihedral angle of 23.5 (2)° between the carboxyl-ate group and its parent ring. Two independent water mol-ecules serve as both donors and acceptor in the construction of undulating hydrogen-bonded host layers with various O-H⋯O contacts ocurring between the anion and two water mol-ecules. At the same time, the tetra-methyl-ammonium cations, as the sphere-like guest species, are arranged in two rows between neighboring host layers, with an approximate inter-layer distance of 7.36 Å, forming a sandwich-like crystal structure.
