Dicaesium magnesium bis-(dihydrogen phosphate(V)) dihydrate.

ABSTRACT: The title compound, Cs(2)Mg(H(2)P(2)O(7))(2)·2H(2)O, is isostructural with the related known isoformular phosphates. The crystal framework consists of corner-sharing MgO(6) and H(2)P(2)O(7) polyhedra, leading to tunnels parallel to the b-axis direction in which Cs(+) ions are located. The H(2)P(2)O(7) unit shows a bent eclipsed conformation. The Mg(2+) ion lies on an inversion center. The water molecules form hydrogen bonds to O atoms of two different dihydrogenphosphate ions, which are further hydrogen bonded to symmetry-equivalent dihydrogenphosphate ions.

Project description:In the title salt, C(8)H(16)N(2)O(4) (2+)·2H(2)PO(4) (-)·2H(2)O, the piperazine ring is located around an inversion center and adopts a chair conformation. The dihydrogen phosphate anions and free water mol-ecules are linked via O-H⋯O hydrogen bonds into two-dimensional hydrogen-bonding layers, which are further connected through O-H⋯O and N-H⋯O hydrogen bonds involving the protonated piperazine into a three-dimensional supra-molecular network.

Bis(dihydrogen norfloxacinium) tri-μ(2)-chlorido-bis-[trichloridobismuthate(III)] chloride dihydrate.

Project description:The title compound, {systematic name: (3-carb-oxy-1-ethyl-6-fluoro-7-piperazin-4-ium-1-yl-1H-quinolin-4-yl-idene)oxonium tri-μ(2)-chlorido-bis-[trichloridobismuthate(III)] chloride dihydrate], (C(16)H(20)FN(3)O(3))(2)[Bi(2)Cl(9)]Cl·2H(2)O, is composed of [Bi(2)Cl(9)](3-) anions lying on crystallographic twofold rotation axes, Cl(-) anions also on twofold axes, C(16)H(20)FN(3)O(3) (2+) cations, and water mol-ecules. The Bi(III) coordination polyhedron is a distorted octa-hedron and two such octa-hedra share a triangular face to form the complex anion. There are three short terminal Bi-Cl bonds [2.5471 (6)-2.5781(5 Å] and three longer bridging bonds [2.8599 (5)-2.9984 (6) Å] in each octa-hedron. Anions, cations and water mol-ecules are linked by hydrogen bonds to form a three-dimensional network. There are also π-π stacking inter-actions between quinoline ring systems, with an inter-planar distance of 3.27 (1) Å.

Poly[[hexa-μ-aqua-diaqua-bis-(μ₄-dihydrogen benzene-1,2,4,5-tetra-carboxyl-ato)magnesiumdisodium] dihydrate].

Project description:The asymmetric unit of the title compound, {[MgNa₂(C₁₀H₄O₈)₂(H₂O)₈]·2H₂O}(n), contains one octa-hedrally coordin-ated Mg(II) atom (site symmetry 2/m), one octahedrally coordinated Na(I) atom (site symmetry 2) and one half of the dihydrogen benzene-1,2,4,5-tetra-carboxyl-ate (btec) ligand, the second half of the ligand being generated by a twofold rotation axis. The basic framework of the title compound features infinite (-Na-Na-Mg-)(n) chains along [10-1] with the metal cations bridged by the coordinating water molecules. The chains are isolated from each other by μ₄-bridging btec ligands, which form inter-molecular O-H⋯O hydrogen bonds to uncoordinated water mol-ecules and the coordinated water mol-ecules of a neighbouring chain. In each btec ligand, there are also intramolecular O-H⋯O hydrogen bonds.

Dihydrogen phosphate mediated supramolecular frameworks in 2- and 4-chloroanilinium dihydrogen phosphate salts.

Project description:The title compounds, 2-chloroanilinium dihydrogen phosphate (2CADHP) and 4-chloroanilinium dihydrogen phosphate (4CADHP), both C(6)H(7)NCl(+) x H(2)PO(4)(-), form two-dimensional supramolecular organic-inorganic hybrid frameworks. In 2CADHP, the dihydrogen phosphate anions form a double-stranded anionic chain generated parallel to the [010] direction through O-H...O hydrogen bonds, whereas in 4CADHP they form a two-dimensional supramolecular net extending parallel to the crystallographic (001) plane into which the cations are linked through strong N-H...O hydrogen bonds.
