Effect of the nature of alcohols on the enthalpy of complexing of cobalt halides with pyridine and its analogs: Effect of the nature of alcohols on the enthalpy of complexing of cobalt halides with pyridine and its analogs. Logachev, V. A.; Dulova, V. I. (Dnepropetr. Khim.-Tekhnol. Inst., Dnepropetrovsk, USSR). Koord. Khim., 2(12), 1625-8 (Russian) 1976. CODEN: KOKHDC. DOCUMENT TYPE: Journal CA Section: 69 (Thermodynamics, Thermochemistry, and Thermal Properties) Section cross-reference(s): 68 Complexing of CoCl2 [7646-79-9] and CoBr2 [7789-43-7] with pyridine and its derivs. in PhCH2OH (I) and cyclohexanol was studied spectrophotometrically (500-700 m.mu.) and calorimetrically. Equil.There are some commonly used reagents with their cas registry numbers 110-86-1 and 260-94-6 in this article. consts. and enthalpies, entropies, and free energies of complex formation of CoCl2L are tabulated for L = pyridine, quinoline, and acridine (II). CoCl2 does not form a complex with II in I because II forms with I a stable compd. which does not break up on reaction with CoCl2. The results are discussed by considering solvation of CoX2 and L. .

Trivalent Cation Substitution Effect into Layered Double Hydroxides Co2Fey Al1-y(OH)6Cl×nH2O: Study of the Local Order: Trivalent Cation Substitution Effect into Layered Double Hydroxides Co2Fey Al1-y(OH)6Cl×nH2O: Study of the Local Order. Intissar, Mourad; Segni, Rachid; Payen, Christophe; Besse, Jean-Pierre; Leroux, Fabrice (Laboratoire des Materiaux Inorganiques, Universite Blaise Pascal, Aubiere 63177, Fr.). Journal of Solid State Chemistry, 167(2), 508-516 (English) 2002 Elsevier Science. CODEN: JSSCBI.Chemicals with cas numbers 7646-79-9 and 487002-74-4 also play role. ISSN: 0022-4596. DOCUMENT TYPE: Journal CA Section: 78 (Inorganic Chemicals and Reactions) Section cross-reference(s): 77 Layered double hydroxide materials Co2FeyAl1-y(OH)6Cl×nH2O (0￡y￡1) were prepd. via chimie douce. The cryst. parameter related to the cation to cation distance obeys the expected variation, showing that the substitution is effective over the entire range. Local order around Co and Fe cations was studied by x-ray absorption spectroscopy. Moduli of the Fourier transform at the Fe K-edge are superimposable, in agreement with an ordered model, although present in small domains since no superlattice is depicted. The ionic resistivity of the samples is highly dependent on the H2O mol. content. The cond. is thermally assisted, and the variation of the slope in the Arrhenius diagram is explained by a Vogel-Tamman-Fulcher-type behavior. Magnetic susceptibility measurements support the proposed cation compn. and indicate the onset of local magnetic order at low temp. (<10 K). The inter-sheet distance influences the magnetic response at low temp., showing the presence of weak interactions between lamellae. .
