	abstract = {A comparison of various group IV-VIII bulk metal nitride catalysts identified Co4N and Fe3N as having higher pyridine hydrodenitrogenation activity per unit area than Mo2N. Formation of the metal nitrides was confirmed by X-ray diffraction and X-ray photoelectron spectroscopy, and all the nitrides were prepared from metal oxide precursors using the same temperature-programmed reaction technique. In general, the specific activity of the metal nitrides decreased with increased hear of formation of the metal nitride.},

	abstract = {Several nickel(II) complexes containing pyridine (py), pyrazine (pyz) or methylpyrazine (mepyz) have been synthesized and characterized by vibrational and electronic spectroscopy, differential scanning calorimetry, and magnetic susceptibility studies to cryogenic temperatures. A comparison of the magnetic properties of the polymeric diazine-bridged complexes, Ni(pyz)(2)X(2) (X = Cl or NO3), Ni(pyz)(p-CH3C6H4SO3)(2), Ni(mepyz)(NO3)(2), and Ni(pyz)(3)(CH3SO3)(2).CH3OH with those of the related monometallic systems, Ni(py)(4)X(2) (X = Cl, p-CH3C6H4SO3 or CH3SO3) and Ni(mepyz)(4)(NO3)(2).H2O provides evidence for weak antiferromagnetic coupling between metal centers mediated by bridging diazine ligands in the former group of compounds. The magnetic properties were analyzed employing a model for S = 1 which takes into account zero-field splitting and employs a molecular field term to account for weak magnetic exchange. The compounds Ni(pyz)Cl-2 and Ni(py)Cl-2, show metamagnetic behaviour with critical fields of 13 and 2 kOe, respectively, at 2 K. In these compounds nickel ions, linked in chains by bridging chlorides, exhibit intrachain ferromagnetic and interchain antiferromagnetic exchange. In Ni(pyz)Cl-2, bridging pyrazine ligands are considered to provide the pathway for the antiferromagnetic coupling resulting in a high critical field.},
