Dipotassium hydrogencarbonate fluoride monohydrate.

ABSTRACT: Single crystals of the title compound, K2(HCO3)F·H2O, were obtained as a secondary product after performing flux synthesis experiments aimed at the preparation of potassium rare earth silicates. The basic building unit of the structure is an [(HCO3)(H2O)F](2-) zigzag chain running parallel to [001]. Both types of anions as well as the water mol-ecules reside on mirror planes perpendicular to [010] at y = 0.25 and y = 0.75, respectively. Linkage between the different constituents of the chains is provided by O-H?O and O-H?F hydrogen bonding. The K(+) cations are located between the chains and are coordinated by two F and five O atoms in form of a distorted monocapped trigonal prism.

Redetermination of dipotassium trichlorido-stannate(II) chloride monohydrate.

Project description:The title compound, K(2)[SnCl(3)]Cl·H(2)O, is the prototype of some isostructural compounds of composition M(2)[SnX(3)]X·H(2)O (M = large monovalent cation; X = halogen). In comparison with a previous study based on photographic data [Kamenar & Grdenić (1962 ▶). J. Inorg. Nucl. Chem.24, 1039-1045], its crystal structure has now been redetermined using CCD-based data in order to gain more accurate values for bond lengths and angles within the [SnCl(3)](-) anion and to locate the H atoms. The [SnCl(3)](-) anion has a trigonal-pyramidal shape and exhibits crystallographic mirror symmetry. With the exception of the K(+) ion which is located on a general position, all other atoms are situated on crystallographic mirror planes. The coordination polyhedron of the cation may be described by means of nine atoms in the form of a monocapped square anti-prism with seven typical K-Cl/O distances and two additional atoms at considerably longer distances. The positions of the H atoms of the water mol-ecule (also lying on a crystallographic mirror plane) could be determined and confirm the existence of a bifurcated O-H⋯Cl hydrogen bond to neighbouring Cl atoms.

l-Leucinium fluoride monohydrate.

Project description:The asymmetric unit of the title hydrated salt, C(6)H(14)NO(2) (+)·F(-)·H(2)O, contains a discrete cation with a protonated amino group, a halide anion and one water mol-ecule. The crystal structure is composed of double layers parallel to (010) held together by N-H?O, N-H?F, O-H?F and C-H?F hydrogen bonds, forming a two-dimensional network, and stacked along the c axis, viz. hydro-philic layers at z = 0 and 1/2 and hydro-phobic layers at z = 1/3 and 2/3.

Dipotassium disulfanilamidate trihydrate.

Project description:The asymmetric unit of the title compound, 2K(+)·2C(6)H(7)N(2)O(2)S(-)·3H(2)O, consists of two potassium cations located on mirror planes, one sulfanilamidate anion in a general position and one and a half mol-ecules of water, one of which is also located on a mirror plane. One potassium cation is seven-coordinated by six sulfonyl O atoms and one water mol-ecule, whereas the other is surrounded by six water O atoms and two sulfonyl O atoms. In the crystal structure, the components are connected into polymeric sheets in the bc plane. The two-dimensional structure is consolidated by N-H?O, O-H?O, O-H?N and C-H?? inter-actions. The layers are further linked into a three-dimensional network via N-H?O, N-H?N and O-H?N hydrogen bonds.

Sodium dipotassium citrate, NaK2C6H5O7.

Project description:The crystal structure of sodium dipotassium citrate, Na(+)·2K(+)·C6H5O7 (3-), has been solved and refined using laboratory X-ray powder diffraction data, and optimized using density functional techniques. The Na(+) and one of the K(+) cations are six-coordinate, with bond-valence sums of 1.13 and 0.92 valence units, respectively, while another crystallographically independent K(+) cation is seven-coordinate with a bond-valence sum of 1.20. The [KO6] and [KO7] polyhedra share edges and corners to form layers perpendicular to the b axis. The distorted [NaO6] octa-hedra share edges to form chains along the a axis. The result is a three-dimensional network. The only O-H⋯O hydrogen bond is an intra-molecular one between the hy-droxy group and a terminal carboxyl-ate group.

Dipotassium dialuminium cyclo-octa-phosphate.

Project description:Single crystals of the title compound, K(2)Al(2)P(8)O(24), were obtained by solid-state reaction. The monoclinic structure is isotypic with that of the Ga(III) analogue and is built of eight-membered phosphate ring anions P(8)O(24) (8-) (2/m symmetry) isolated from each other and further linked by isolated AlO(6) octa-hedra ( symmetry) by sharing corners. Each AlO(6) octa-hedron is linked to four P(8)O(24) (8-) rings in such a way that two rings are linked through bidentate diphosphate groups attached in the cis positions on two opposite parallel edges of the octa-hedron. The two other rings are linked via corner-sharing to the two remaining corners in the trans positions of the AlO(6) octa-hedron. Each P(8)O(24) (8-) ring anion is linked to eight AlO(6) octa-hedra. More accurately, each ring anion is linked to four AlO(6) octa-hedra through bidentate diphosphate groups attached in the cis positions to the AlO(6) octa-hedron and to the four remaining octa-hedra by sharing corners. This three-dimensional linkage delimits channels running parallel to [001] in which the ten-coordinated K(+) cations (2 symmetry) are distributed over two columns. These columns alternate with empty octa-gonally-shaped channels expanding through the P(8)O(24) (8-) ring anions.

Lithium dipotassium citrate monohydrate, LiK2C6H5O7(H2O).

Project description:The crystal structure of dilithium potassium citrate monohydrate, Li+·2K+·C6H5O7 3-·H2O or LiK2C6H5O7·H2O, has been solved by direct methods and refined against laboratory X-ray powder diffraction data, and optimized using density functional techniques. The complete citrate trianion is generated by a crystallographic mirror plane, with two C and three O atoms lying on the reflecting plane, and chelates to three different K cations. The KO8 and LiO4 coordination polyhedra share edges and corners to form layers lying parallel to the ac plane. An intra-molecular O-H⋯O hydrogen bond occurs between the hydroxyl group and the central carboxyl-ate group of the citrate anion as well as a charge-assisted inter-molecular O-H⋯O link between the water mol-ecule and the terminal carboxyl-ate group. There is also a weak C-H⋯O hydrogen bond.

Dipotassium zinc tetra-iodate(V) dihydrate.

Project description: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.

Synthesis and crystal structures of 3,6-di-hydroxy-picolinic acid and its labile inter-mediate dipotassium 3-hy-droxy-6-(sulfonato-oxy)pyridine-2-carboxyl-ate monohydrate.

Project description:A simplified two-step synthesis of 3,6-di-hydroxy-picolinic acid (3-hy-droxy-6-oxo-1,6-di-hydro-pyridine-2-carb-oxy-lic acid), C6H5NO4 (II), an inter-mediate in the metabolism of picolinic acid, is described. The crystal structure of II, along with that of a labile inter-mediate, dipotassium 3-hy-droxy-6-(sulfonato-oxy)pyridine-2-carboxyl-ate monohydrate, 2K+·C6H3NO7S2-·H2O (I), is also described. Compound I comprises a pyridine ring with carboxyl-ate, hydroxyl (connected by an intra-molecular O-H⋯O hydrogen bond), and sulfate groups at the 2-, 3-, and 6-positions, respectively, along with two potassium cations for charge balance and one water mol-ecule of crystallization. These components are connected into a three-dimensional network by O-H⋯O hydrogen bonds arising from the water mol-ecule, C-H⋯O inter-actions and π-π stacking of pyridine rings. In II, the ring nitro-gen atom is protonated, with charge balance provided by the carboxyl-ate group (i.e., a zwitterion). The intra-molecular O-H⋯O hydrogen bond observed in I is preserved in II. Crystals of II have unusual space-group symmetry of type Abm2 in which extended planar networks of O-H⋯O and N-H⋯O hydrogen-bonded mol-ecules form sheets lying parallel to the ac plane, constrained to b = 0.25 (and 0.75). The structure was refined as a 50:50 inversion twin. A minor disorder component was modeled by reflection of the major component across a mirror plane perpendicular to c.
