the structural and energetic characteristics of o3–h2o complexes have been investigated by means of b3lyp, mp2, mp4(sdtq), ccsd(t) and qcisd(t) methods in conjunction with the aug-cc-pvdz and aug-cc-pvtz basis sets. six conformers were found for the o3–h2o complex. two different intermolecular interactions were expected to participate in the formation of complexes, namely conventional o∙∙∙h hyd...

The structural and energetic characteristics of O3–H2O complexes have been investigated by means of B3LYP, MP2, MP4(SDTQ), CCSD(T) and QCISD(T) methods in conjunction with the AUG-cc-pVDZ and AUG-cc-pVTZ basis sets. Six conformers were found for the O3–H2O complex. Two different intermolecular interactions were expected to participate in the formation of complexes, namely conventional O∙∙∙H hyd...

Short Abstract 3-Formylsalicylic acid (Hfsal) covalently bound to chloromethylated polystyrene (PS) cross-linked with 5% divinylbenzene reacts with DL-alanine and L-isoleucine to give the Schiff-base tridentate ligands PS-H2fsal-DL-Ala and PS-H2fsal-L-isoleu, respectively. These anchored ligands on reaction with VOSO4 and Cu(CH3COO)2.H2O form complexes PS-[VO(fsal-DL-Ala)(H2O)], PS-[Cu(fsal-DLA...

A DFT study of U(VI) hydroxy complexes was performed with special attention paid to the [(UO2)3(OH)5(H2O)4-7]+ and [(UO2)4(OH)7(H2O)5-8]+ species. It was established that the ionicity of the U=O bond increased when moving from [(UO2)(H2O)5]2+, [(UO2)2(OH)(H2O)8]3+, [(UO2)2(OH)2(H2O)6]2+, [(UO2)3(OH)5(H2O)4-6]+ to [(UO2)4(OH)7(H2O)5-8]+ species. In both [(UO2)3(OH)5(H2O)4-6]+ and [(UO2)4(OH)7(H2...

Schiff base complexes of transition metals are of particular interest to inorganic chemists because of their structural, spectral and chemical properties, which are often strongly dependant on the nature of the ligand structure. Large number of metal (II) complexes with Schiff-base ligands has been extensively studied for their interesting structural specialties, applications and properties. Th...

The aim of this research is to develop new mordants and a wide range of colors for natural dyeing of silk. In this study, two new erbium(ΙΙΙ) complexes, [Er(AO)(H2O)7](OAc)3 and [Er(AMH)(H2O)6](OAc)3 (AO = acridine orange, AMH = azomethine-H, and OAc = acetate anion), were synthesized, characterized and used as a mordant for the natural dyeing of silk yarns with an aqueous extract of green waln...

The thermal decomposition processes for metal complexes of nalidixic acid (NAL) viz: Co (NAL) OH , VO(NAL)2(H2O)3 , UO2 (NAL) 2(H2O)2 , Ru(NAL)2Cl(H2O) has been accomplished on the basis of TG, DTG and DTA studies, and the mechanism conforms to the stoichiometry of the complexes based on elemental analysis.

β-diketonates are customary bidentate ligands in highly luminescent ternary europium complexes, such as Eu(β-diketonate)3(L)2, where L stands for a nonionic ligand. Usually, the syntheses of these complexes start by adding, to an europium salt such as EuCl3(H2O)6, three equivalents of β-diketonate ligands to form the complexes Eu(β-diketonate)3(H2O)2. The nonionic ligands are subsequently added...
