Physico-chemical study of new supramolecular-architectured hybrid organic-inorganic sulfates incorporating diammoniumdiphenylsulfone cations.

Two new hybrid organic-inorganic compounds, which incorporate 3,3'-diammoniumdiphenylsulfone or 4,4'-diammoniumdiphenylsulfone cations and sulfate anions, were synthesized and analyzed in detail. The crystal structures of both systems were established using single-crystal X-ray diffraction analysis. Crystallographic study revealed that the crystals of both investigated compounds were constructed of repeatedly occurring organic and inorganic layers and allowed the description of their structural features.

Crystal structure, spectroscopic measurement, optical properties, thermal studies and biological activities of a new hybrid material containing iodide anions of bismuth(iii).

As part of our interest in halogenobismuthate(iii) organic-inorganic hybrid materials, a novel compound named bis(4,4'-diammoniumdiphenylsulfone) hexadecaiodotetrabismuthate(III) tetrahydrate with the chemical formula (CHNOS)[BiI]·4HO, abbreviated as (HDDS)[BiI], has been prepared by a slow evaporation method at room temperature. This compound was characterized by single crystal X-ray diffraction (SCXRD), spectroscopic measurements, thermal study and antimicrobial activity. The examination of the molecular arrangement shows that the crystal packing can be described as made of layers of organic [CHNOS] entities and HO molecules, between which tetranuclear [BiI] units, isolated from each other, are inserted.

3-Amino-4-(1,3-benzoxazol-2-yl)-5-(cyclo-hexyl-amino)-thio-phene-2-carbo-nitrile.

In the title compound, C18H18N4OS, the cyclo-hexyl ring adopts a chair conformation. The other rings of this compound lie almost in the same plane, with a mean deviation of 0.03 (2) Å from the least-squares plane defined by the 14 constituent atoms.
