The lamellar architecture of 1,6-hexamethylenediammonium tetrachlorocobaltate(II)

In the title compound, (C6H18N2)[CoCl4], organic dications and inorganic dianions interact with each other through N-H...Cl hydrogen bonds, forming infinite two-dimensional sheets of anions parallel to the ac plane. Alkyl chains act as spacers between these sheets. Only three Cl atoms are involved in hydrogen bonding with ammonium groups. The asymmetric unit consists of one anion together with half of each of two cations on inversion centres

Self-Assemblies of Extended Hydrogen-Bonded Arrays Using 1,4-Butanebisphosphonic Acid as a Versatile Building Block

Two organic salts of 1,4-butanebisphosphonic acid, bis(ethylenediammonium) butanebisphosphonate hydrate (1) and bis(hexamethylenediammonium) butanebisphosphonate hydrate (2), have been structurally characterized using single-crystal x-ray diffraction analyses. Compound 1 exhibits a H-bonded pillared bilayered structure, in which etheylenediammonium cation acts as a spacer between the anions resulting in the formation of two types of cavities. The larger cavity is filled by four water molecules though having hydrophobic character. Thus, the material behaves as a nanoporous organic solid. Compound 2 shows a multidimensional hydrogen bonding networks: one-dimensional arrays parallel to the b axis and two-dimensional sheets parallel to the ab plane. The N--H···O--P hydrogen bonds, forming H-bonded supramolecular networks, are regarded to be strong and directional hydrogen bonds

Radical Additions of Bis(trimethylsilyl)phosphite to Vinyltrimethylsilane and Vinyltriethoxysilane: Crystal Structure of 2-Trimethylsilylethylphosphonic Acid

Organosilicon-phosphonate compounds with the general formula (R)n(RO)3mnSi(CH2)mP(O)(OSiR\u273)2 are designed for application as novel materials for surface treatments and modifications. A solvothermal method based on the reaction of bis(trimethylsilyl)phosphite with vinyltrimethylsilane and vinyltriethoxysilane in the presence of a peroxide in benzene solvent was used to synthesize the silyl-substituted esters of organosilicon-phosphonate compounds. 2-Trimethylsilylethanephosphonic acid was prepared from its bis(trimethylsilyl) ester by alcoholysis. The crystal structure of the acid consists of two-dimensional arrays built up from the (P--)O--H\ub7\ub7\ub7O--P hydrogen bonds
