Etude par spectroscopie (IR et Raman) de l'éthylène diammonium bis dihydrogénomonophosphate NH3(CH2)2NH3(H2PO4)2

Abstract Infrared and Raman Spectra of single crystal and polycrystalline samples of NH 3 (CH 2 ) 2 NH 3 (H 2 PO 4 ) 2 and of its deuterated polycrystalline derivative have been recorded at 298 K. All the observed bands have been assigned using group theory. The IR and Raman spectra are consistent with the presence of strong OH⋯O hydrogen bonds.

Crystal structure of NH3(CH2)2NH3BiCl5·2H2O

AbstractThe ethylenediammonium pentachlorobismuthate(III) dihydrate salt is monoclinic with the following unit cell dimensions: a = 10.902(8)Å, b = 7.926(6)Å, c = 15.199(6)Å, β = 96.40(1)°, space group P21/n with Z = 4. The structure shows a layer arrangement parallel to the
