Abstract (C12H30N2)2BiCl6.Cl·2H2O compound crystallizes at 296 K in triclinic system with P-1 space group [Z = 2; a = 10.532(3) A, b = 12.143(4) A, c = 16.295(5) A; α = 97.543(13)°, β = 101.451(14)°, δ = 97.484(13)°]. DSC analysis showed three anomalies (338 K, 347 K, and 367 K) in heating, not reproducible in cooling, which are due to dehydratation process, above which a stable anhydrous compound undergoes a second order phase transition at 483/470 K (heating/cooling). TG-DTG analyses showed th...

Abstract Submolecular-level variation of polypropylene (PP) caused by aging treatment is studied by two-dimensional (2D) small-angle X-ray scattering (SAXS) in conjunction with 2D correlation spectroscopy. PP samples were prepared by a T-die extrusion method and then probed by 2D SAXS. Direction-depending SAXS profile data were obtained by extrusion the SAXS intensities along the direction from 90° (i.e. direction of extrusion) to 120° on the 2D SAXS image. 2D correlation spectra derived from th...

Abstract It is proved by the 1H and 13C data that the thiosemicarbazone with the furyl substituent is synthesized as the E isomer. However, this thiosemicarbazone undergoes the solvent-induced E/Z isomerization when standing in chloroform, despite the fact that the other thiosemicarbazones with a heteroaryl or aryl substituent do not exhibit such phenomenon. It is established that the N–H⋅⋅⋅O intramolecular hydrogen bond in the Z isomer of furyl thiosemicarbazone promotes the E/Z isomerization. ...

Abstract The novel complex, (2-amino-5-picolinium) tetrachlorocobaltate(II), (2A5PCoCl4) have been synthesized and crystallized to the monoclinic system with space group P21/c and the lattice parameters obtained are a = 8.0734 (6) A, b = 14.6297 (11) A, c = 15.6913 (11) A, β = 103.034 (4) °, V = 1805.6 (2) A3 and Z = 4. His atomic arrangement can be described as an alternation of inorganic and organic layers, [CoCl4]2- tetrahedral anions and 2-amino-5-picolinium cations are connected by bifurcat...
Abstract This research aims to develop new hydrophobically modified derivatives of xanthan gum with amphiphilic character by the grafting of octyl chains onto xanthan gum (XG) backbone using a Williamson synthesis. The etherification reaction between 1-Octyl chloride and the hydroxyl groups of XG at a reagent/monomer ratio (R=1) was carried out in two different reaction media: Ethanol and Dimethylsulfoxyde (DMSO). The two derivatives HMXG1 and HMXG2, obtained respectively in ethanol and DMSO wer...

Abstract The crystal of nonlinear optical (NLO) interest, organic compound Toluidine Tartrate (TT) with molecular formula C11 H15 N O6 has been crystallized from solvent ethanol at room temperature using slow evaporation solution growth technique. Single crystal XRD analysis was performed and reveals that the crystal is grown with triclinic system with non centrosymmetric space group P1. Various functional groups of the compound were analysed using FTIR and FTRaman spectral analysis. The molecul...

Abstract Vanadium lactate, malate and citrate [Ni(phen)3]2[VV2O4(lact)2]Cl2·20H2O·2EtOH (1), [Ni(phen)3][VIVO(mal)(phen)]Cl·14H2O (2) and [Ni(phen)3]2[VIV2O2(Hcit)(cit)]Cl·17H2O (3) (H2lact = lactic acid, H3mal = malic acid, H4cit = citric acid, and phen = 1,10-phenanthroline) have been obtained with large counter cation [Ni(phen)3]2+. In mononuclear complex 2, vanadium atom exists in a distorted octahedral environment. The distance of V–O bond (α-alkoxy) in 2 is significantly shorter than V–O b...
Abstract Graph theory is the most powerful tools in the mathematics and computer science, also study of descriptors in quantitative structure property relationship (QSPR) and quantitative structure activity relationship (QSAR) studies in the chemistry science. Let G = ( V ( G ) , E ( G ) ) be a simple molecular graph without directed and multiple edges and without loops. A topological index is a numerical descriptor of the molecular structure derived from the corresponding molecular graph. There...

Abstract Novel task dicationic ionic liquids (Ts-DiILs) 6–29 were designed and synthesized, under both conventional and microwave conditions; through molecular hybridization of the appropriate bispyridines having a hydrazone linkage as spacer with some alkyl functionalized esters forming the counter cations. Beside the synthesized halogenated DiILs 6–11, fluorinated metal anions were introduced via metathesis reaction in order to create new dipyridinium ionic liquid-hydrazone hybrids 12–29. All ...

Abstract Structures of solid copper complexes with aroylhydrazones obtained from nicotinic acid hydrazide and salicylaldehyde derivatives differing in substituents on the benzene ring were analysed by means of infrared (IR) and Raman spectroscopy. Studied aromatic hydrazones acted as neutral, monoanionic or dianionic tridentate ligands, depending on the tautomer form adopted during the complexation process. Various additional substituents on the salicylaldehyde originated ring were not involved ...
