TL;DR: In this article, a stuffed tridymite structure of CaAl 2 O 4 was re-examined by single crystal X-ray data and the orientation of the tetrahedrals in this tridyclic structure was discussed in comparison with other known compounds.

TL;DR: In this article, the reactionivity of cis dichloro Pt(II) amine antitumor complexes is reduced by Cl−, OH− and dihydroxy bridged dimer substituents, the formation of which is time dependent.

TL;DR: In this paper, the rate of oxygenation of ferrous ion was measured in neutral and slightly acidic solutions containing various anions and the role of the respective anions in the oxygenation was explained by assuming that the complex of the anion with ferrous ions constitutes the reacting species.

TL;DR: In this article, the initial rate of dissolution of several crystalline forms of goethite (α-FeOOH) has been measured as a function of solution conditions, including hydrogen ion concentration, anion concentration (chloride or perchlorate), and temperature.

TL;DR: In this paper, a liquid-liquid chemical exchange system utilizing this reaction was considered technically feasible for separation of calcium isotopes, and the single stage separation factor for isotopes differing by one mass unit was 1·0010 ± 0·0002 (95% C.I.).

TL;DR: In this paper, a general discussion of the electrochemical behavior of metatungstate ion and other polyanions with Keggin structure is presented, especially the products with 12, 18, 24 and 32 electrons per mole.

TL;DR: The exchange of Mn(II, Co(II), Ni(II) and Zn(II)-on crystalline zirconium phosphate has been examined in this article, where the exchange does not represent a true equilibrium since the site binding traps the ions within the crystal lattice.

TL;DR: In this paper, the ion exchange equilibrium of caesium ions on potassium-zinc-hexacyanoferrate(II) was studied in batch and in column experiments, and the equilibrium data indicate high selectivity for caesIUM relative to other mono- and divalent ions.

TL;DR: In this article, the ion exchange properties of ϑ-ZP for alkali, alkaline earth and some divalent transition metal ions have been investigated in detail and a comparison with Zr(HPO4)2 · H2O is made.

TL;DR: In this paper, the CsU ǫO system was investigated by means of X-ray analysis, thermal analysis and phase studies, and eight cesium uranate phases, in which uranium is hexavalent, were found.

TL;DR: In this paper, the reaction of the ligands with the Pt(II) complexes proceed slowly because of the sluggishness of Pt-II substitutions and the small fractions of ligands having p K a from 9.3 to 9.8 in anionic basic form.

TL;DR: In this article, a hexagonal version of the LuMnO3 structure was obtained at atmospheric pressure of 0.34 kbar, 1000°C, where the In3+ ions are located in fivefold-coordinated trigonal-bipyramidal sites, and the Ln3+ ion are sevenfold coordinated.

TL;DR: In this paper, the substituted isopolyanions (SIsP) family has been defined and four new compounds belonging to the SIsP family have been prepared from aqueous solutions, which have been separated as Na, K, C s, or tetramethylammonium salts.

TL;DR: Kinetic data, obtained by the stopped-flow technique, showed that the reactions progress through an SN 1 mechanism according to: FeOH2 + H2cat⇄krkƒFecat+ + H+ +H2O, and kf values are independent of substituent groups present on the ligand, which affect only the reverse reaction rates.

TL;DR: In this paper, the rate constants in quenching reaction of uranyl luminescence by halide ions were determined from luminecence lifetime measurement, showing that an electron transfer process plays an important role in the quench of halide ion.

TL;DR: A systematic study of the K U O and Rb U O systems is presented in this paper, where four distinct uranates-VI with metal/uranium ratio's 2.0, 1.5, 0.5 and 0.286 exist.

TL;DR: In this article, a detailed investigation of the ion exchange mechanism of alkaline earth ions with ZrHNa(PO 4 ) 2 ·5H 2 O has been carried out.

TL;DR: A series of nickel(II) and copper (II) chelates with polydentate ligands derived from the condensation of salicylaldehyde with some dicarboxylic acid dihydrazides have been prepared.

TL;DR: In this paper, two mechanisms of the complex formation of crystalline α-zirconium phosphates with these amines are proposed as follows: (1) Exchange reaction of interlayer cations of the calcined organic bases into the interlayer spaces.

TL;DR: In this article, the long chain compounds form bilayers between the niobate sheets and are arranged in gauche-block structures, which can change their dimensions by intercalation of small polar organic molecules.

TL;DR: In this paper, the authors investigated the thermal decomposition of barium titanyl oxalate tetrahydrate (BTO) using TGA, DTG and DTA techniques and gas and chemical analysis.

TL;DR: In this paper, the synthesis and characterization of trans-TcX4L2 and mer-tcX3L3 (X = Cl and Br, and L = PMe2Ph, PEt2Ph and PPh3) are reported.

TL;DR: In this article, the ability of di(2-ethylhexyl) phosphoric acid (HDEHP) complexes to react with free HDEHP was studied by viscosity measurements.

TL;DR: In this paper, the magnetic moments of the perchlorate complexes show metal-metal interaction whereas all other complexes show normal magnetic behaviour, and the electronic spectra of the chloride and the bromide complexes indicate a tetrahedral structure for them, while the other complexes are in favour of a square or distorted octahedral structure.

TL;DR: In this article, the stoichiometries of the extraction of Y 3+ +2.5(HY) 2 o ⇌MY(HY 2 ) 2 o +3H A + where the subscripts A and O refer, respectively, to mutually equilibrated aqueous and organic phases.
