  Solid-state kinetics of thermal release of pyridine and morphological study of [Ni(ampy)2(NO3)2]; ampy=2-picolylamine

  摘要：

  The re-examined X-ray crystal structure of [Ni(ampy)(2)(NO3)(2)]; ampy=2-picolylamine belongs to monoclinic P2(1)/c space group having, a=8.73510(10)A, b=8.73690(10)A, c= 10.26480(10)A and beta=101.5610(10)degrees. The microscopic feature calcined at 600 C displays a thread type fiber of NiO. The thermogravimetric analysis shows that the thermal decomposition occurs in three steps where the removal of ligand occurs in an exothermic process. The activation energy was estimated with both iso-conversional and multivariate non-linear-regression methods. Friedman method agrees with a first-order kinetics having activation energy E and logarithmic pre-exponential factor A, 41 +/- 1 kJ mol(-1) and 2.54, respectively. Multivariate non-linear-regression methods show expanded Prout-Tompkins Bna model is the best fit model with highest correlation coefficient 0.999998 followed by Cn which corresponds to the nth order reaction with auto catalysis through the reactants. The calculated apparent activation energies are consistent with iso-conversional methods. The corresponding function f(a), activation energy E and logarithmic pre-exponential factor A of Bna model, are (1-alpha)(2.08)alpha(1.0236E-3), 42 kJ mol(-1) and 3.12, respectively, and those of Cn model are (1-alpha)(2.07)(1 + 0.0144 alpha), 42 kJ mol(-1) and 3.11, respectively. The calculated rate constant and half-life time from iso-concentration plot are 2.381 x 10(-3) s(-1) and 291 s, respectively. (c) 2006 Published by Elsevier B.V.

  Synthesis and characterization of a new molecular magnet, [Ni(ampy)2]3[Fe(CN)6]2·6H2O, and synthesis, crystal structure and magnetic properties of its mononuclear precursor, trans-[Ni(ampy)2(NO3)2] (ampy=2-aminomethylpyridine)

  摘要：

  The reaction of trans-[Ni(ampy)(2)(NO3)(2)] (1) (ampy = 2-aminomethylpyridine) with K-3[Fe(CN)(6)] affords a cyano-bridged bimetallic system, (Ni(ampy)(2)](3)[Fe(CN)(6)](2). 6H(2)O (2). The crystal structure of compound 1 has been solved. It crystallizes in the monoclinic space group P121/c1 and consists of neutral mononuclear entities with the nickel atom located on an inversion center. The nickel atom exhibits a (pseudo)octahedral stereochemistry with the two nitrate ligands coordinated in trans positions. The Ni-N bond distances vary from 2.0690(15) to 2.0811(15) Angstrom, while the trans-Ni-O distances are 2.1665(13) Angstrom. The cryomagnetic investigation of compound 1 reveals an intermolecular ferromagnetic coupling (theta = + 3.7 K), which is mediated by the pi-pi stacking interactions between the mononuclear entities. Compound 2 is a soft ferromagnet with T-c = 7.5 K and a coercive field of 330 G at 2 K. (C) 2000 Elsevier Science Ltd. All rights reserved.
