Polydentate Ligands

A new series of octahedral cobalt(II) complexes are formed when CoX2(X = Cl, Br, I, SCN) reacts with Hg(SCN)2 in the presence of Lewis bases. These complexes of stoichiometry CoHg(SCN)4•2L (L = THF, dioxane, pyridine, aniline) are pink to violet solids which slowly decompose to the blue crystalline solid, CoHg(SCN)4, the stable magnetic susceptibility standard. On further reaction of CoHg(SCN)4•2THF with mono-, bi-, and polydentate ligands in dry ethanol, complexes of the following types are obtained: CoHg(SCN)4•2L (L = PΦ3), CoHg(SCN)4•2LL (LL = trien), CoHg(SCN)4•3LL (LL = en, bipy), and CoHg(SCN)4•4LL (LL = phen). The stoichiometry of these were determined by elemental analysis. Possible structures of these are discussed with the help of mid and far infrared, visible, and ultraviolet spectroscopy, magnetic susceptibility, and X-ray powder diffraction. Some new i.r. bands like Co—P, Co—N, and Hg—S are assigned in the low region.

Isolated Compound

Dithallium phthalocyanine ( Tl 2 Pc ) has been synthesized from pure Tl metal and o-phthalodinitrile. The isolated compound was characterized by elemental analysis, X-ray powder diffraction, electron diffraction and EDX spectroscopy. Based on these results, the compound synthesized by the present method was concluded to be Tl 2 Pc . The electrical conductivity of this powdery Tl 2 Pc was measured and it exhibited the semiconductive property, in contrast with a previous report.

An anionic cadmium tris-dicyanamide compound (Et4N)[Cd(N(CN)2)3]·3/4H2O 1 has been synthesized and characterized by elemental analysis, IR spectroscopy, thermogravimetric analysis, X-ray powder diffraction, and X-ray crystallography. The anions form extended sheets with retention of (4,4) connectivity in the absence of π···π interactions within the cation layers, and with octahedral geometry about individual CdII ions.

Krypton Difluoride

The fluorination of ruthenium tetroxide RuO4 was attempted by using either fluorine or krypton difluoride KrF2 in HF solution. Of the two fluorinating agents, only KrF2 was found to be powerful enough to react with RuO4 and to transform it into ruthenium oxide tetrafluoride RuOF4. This oxide fluoride of ruthenium VI was characterized by elemental analysis, X-ray powder diffraction, and infrared absorption spectroscopy. Keywords: ruthenium tetroxide, ruthenium oxide tetrafluoride, krypton difluoride, fluorination.

Tb-MA-Phen mononuclear rare earth complexes were prepared. The structure and properties of the complexes were characterized by elemental analysis, FT-IR and UV, TA, X-ray powder diffraction and SEM. Moreover, the rare earth ions were doped into the polymer matrix using the combinatorial method. High luminescence copolymer was synthesized by polymerizing α-methyl methyacrylate (MA) and Styrene (St) with terbium-methacrylate complex in solution with AIBN as initiator, respectively.

ABSTRACTA novel electroactive nanostructured silver molybdenum oxyfluoride (SMOF) perovskite was successfully synthesized via mechanochemistry through the use of AgFx and MoO3. The structure of the SMOF perovskite has been examined utilizing X-ray powder diffraction (XRD) combined with X-ray absorption spectroscopy (XAS) and elemental analysis. The SMOF perovskite exhibited a very good electrochemical activity. A detailed in-situ electrochemical study by XRD and XAS was carried out. Finally, preliminary work on fabrication of a metallic Ag2F phase and optimization of the rate capability of SMOF perovskite is presented.

The present paper is interested in the study of compounds from the apatite family with the general formula Ca10 (PO4)6A2. It particularly brings to light the exploitation of the distinctive stereochemistries of two Ca positions in apatite. In fact, Gd-Bearing oxyapatiteCa8 Gd2 (PO4)6O2 has been synthesized by solid state reaction and characterized by X-ray powder diffraction. The site occupancies of substituents is0.3333 in Gd and 0.3333 for Ca in the Ca(1) position and 0. 5 for Gd in the Ca (2) position.  Besides, the observed frequencies in the Raman and infrared spectra were explained and discussed on the basis of unit-cell group analyses.
