“…The band near 1575 cm\ can be assigned to the (NH )> bending vibration. This band is indicative of the presence of the ethylenediamine molecule in its protonated form (35,43), in good agreement with the structural results. The bending modes of the }CH } groups in the ethylenediammonium appear in the 1400}1200 cm\ range.…”

“…The O}P}O angles are in the range from 103.0(1)3 to 113.2(1)3. In the ethylenediammonium cation, the C}C and C}N bond distances are in the range usually found for this molecule (35) and the angles deviate slightly from the ideal value expected for an sp hybridation. The three-dimensional framework of this compound is formed by a complicated scheme of hydrogen bonds established between the water molecules of the NiO octahedra, the hydrogen phosphate anions, and the ethylenediammonium cations.…”

“…According to several spectroscopic studies on diphosphates and metallic complexes [9][10][11][12][13] the IR spectrum of the title compound ( fig. 4) can be decomposed into three regions: 40-300 cm -1 for the external modes of the anion and the cation, 300-1200 cm -1 for the internal modes of the anion and 400-3400 cm -1 for the internal modes of the cation.…”

Physicochemical properties of (C 6 H 18 N 2 )H 2 P 2 O 7 .2H 2 O denoted DHDP are discussed on the basis of X-ray crystal structure investigation. The compound crystallises in the triclinic system with P1 space group. Its unit cell dimensions are a=13.719(1)Å, b=14.188(3)Å, c=9.177(1)Å, α=108.50(1)°, β=91.11(1)°, γ=115.47(1)°, V=1503.8(4)Å 3 and Z=4. The structure has been solved using direct methods and refined to a reliability R factor 0.0401 for 4778 reflections. The main feature of the atomic arrangement of DHDP is the existence of infinite rows, parallel to the c direction of the unit cell, composed of H 2 P 2 O 7 groups. These phosphoric rows are organised to create, with the help of the organic cation, large rectangular channels in which the unstable water molecule are located since they have high thermal parameters. Phosphoric anions and organic cations have no internal symmetry. DSC and TG-DTA show that dehydration occurs in one step. Such dehydration process may be related to the similar environments on the water molecules residing in the channel.

“…Most characteristic features in these compounds are the tendency of organic moieties to assemble networks via intricate hydrogen bonding systems (Gharbi et al, 1994;Shan & Huang, 1999;Capitelli et al, 2006). The frequent cases of isostructurality found are typical of the lanthanide compounds (Ni et al, 1995, Tahiri et al, 2006, due to their large ionic radii, which decrease as the atomic number increase, the so called "Lanthanide contraction".…”

Diphosphate / Lanthanide / Ethylenediamine / Hydrogen bond / Single crystal structure analysis / Powder diffraction structure analysis / X-ray diffraction Abstract. Crystals of lanthanide ethylenediamine diphosphates Ln 2 (NH 2 (CH 2 ) 2 NH 2 )(HP 2 O 7 ) 2 Á 4 H 2 O (Ln ¼ Eu (1), Tb (2), Er (2)) have been synthesized and investigated by single crystal X-ray diffractometry (Eu and Tb phases) and by powder X-ray diffractometry (Er phase). The three structures resulted to be isostructural within triclinic space group P 1 1, with unit cell parameters of a ¼ 6.5050(6) A; b ¼ 6.9990(2) A; c ¼ 9.8450(9) A; a ¼ 81.548(5) ; b ¼ 80.631(19) ; g ¼ 88.369(9) ; V ¼ 437.44(6) A 3 (1), a ¼ 6.4360(7) A; b ¼ 6.9480(12) A; c ¼ 9.816(4) A; a ¼ 81.987(19) ; b ¼ 80.595(16) ; g ¼ 88.591(13) ; V ¼ 428.82(19) A 3 (2), a ¼ 6.39658(2) A; b ¼ 6.86682(2) A; c ¼ 9.78849(3) A; a ¼ 81.6811(4) ; b ¼ 80.2304(3) ; g ¼ 88.3812(3) ; V ¼ 419.255(3) A 3 (3). The three-dimensional network is built up by the repetition of ab-parallel layers of LnO 8 polyhedra corner-sharing with (HP 2 O 7 ) groups; ethylenediamine molecules lie between such layers, acting both as receptors and donors in strong hydrogen bonds which assure the stabilizing of the entire framework.
