“…The elimination of the multicomponent sub-bands ( Figure 5) at equal dichroic ratio indicates the origin of these sub-maxima as result of the crystal field effect. [23][24][25][26][27][28][29][30] This result is also in accordance with the crystallographic data, supporting the equal polarization of the B 1 sub-bands as well as those of the ν P O stretching vibration. The corresponding transition moments are co-linearly oriented in each of the molecules in the unit cell.…”

“…The oriented samples were obtained as a colloid suspension in a nematic liquid crystal ZLI 1695 following the approach given in refs. [23][24][25][26][27][28][29][30] UV-VIS-NIR spectra were recorded with an Evolution 300 spectrometer (Thermo Scientific) using methanol as solvent 13 C, and 31 P NMR measurements were performed at 298 K with a Bruker DRX-400 spectrometer using 5 mm tubes and CD 3 CN as solvent.…”

2-Oxo-2H-chromen-3-yl)phosphonic acid monoethyl ester trihydrate (1) was synthesized, isolated, and spectroscopically as well as structurally characterized by means of single crystal X-ray diffraction; conventional and linear-polarized IR spectroscopy; electronic (UV-VIS-NIR) spectroscopy; 1 H, 13 C, and 31 P NMR. Quantum chemical DFT calculations have been performed in order to obtain information on the electronic structure and vibrational properties of 1, thus supporting the experimental data. The correlation between the structure and spectroscopic characteristics is discussed.

“…The vibrations at 3258 cm −1 corresponds to the -NH 3 + group, the protonated primary amine -NH 2 , located in the range 3350-3100 cm −1 [15,29]. The band located at 3145 cm −1 in AMB is shifted to ≈3158 cm −1 in the AMB-GLU spectrum; it confirms the secondary amine protonation [17]. The band at ≈2930 cm −1 can be attributed to the -NH 2 + stretching vibration [29].…”

“…The secondary amine presents a band of medium intensity at 1616 cm −1 deformation vibration of the protonated secondary amine -NH 2 + . In the 1650-1475 cm −1 range, the IR bands at 1601 and 1569 cm −1 , 1558 and 1527 cm −1 can be assigned to the NH 3 + δ as and δ as bending vibrations [17]. Table 1 contains the frequencies' assignments for the AMB and AMB · Glu, respectively.…”

Abstract. Ambazone monohydrate C 8 H 11 N 7 S · H 2 O (AMB), a well-known antimicrobial compound, was used together with Glutamic Acid C 5 H 9 NO 4 (Glu) to obtain a new solid form using the solvent-drop grinding procedure. The screening of the new solid form was best achieved by the combined use of X-ray Powder Diffraction (XRPD) and several spectroscopic techniques (Fourier Transformed Infrared Spectroscopy (FTIR), X-ray Photoelectron Spectroscopy (XPS), Raman and 13 C-NMR spectroscopy) together with Differential Scanning Calorimetry (DSC), Differential thermal analysis and thermogravimetry (DTA-TGA). The combination of the mentioned analytical techniques allows the compound to be assigned to an ambazone-glutamate salt which crystallizes in monoclinic system having the following lattice parameters: a = 9.8352, b = 4.7014, c = 40.0987 Å and β = 94.505• . DSC, TGA data and the before mentioned spectroscopic techniques support the ambazone-glutamate salt formation.

Organic cations influence the crystal packing and, less commonly, the electronic structure of hybrid organic-inorganic materials. Two new hybrid compounds prepared from solution, (PEA)SbCl 6 and (PEA) 4 Sb 2 Cl 12 (PEA = phenylethylammonium), demonstrate how the aromatic PEA cation modifies the crystal and electronic structures relative to inorganic antimony chlorides. In (PEA)SbCl 6 the ethylammonium conformation results in a polar and chiral crystal structure, and the bandgap is characterized by organic-inorganic charge transfer. In the mixed-valence (PEA) 4 Sb III Sb V Cl 12 the structure is a uniaxial elongation of that of inorganic analogs and the optoelectronic properties combine features of intervalence charge transfer and organic-inorganic charge transfer.
