Important applications of the NiII, PdII and PtII complexes [M(Hdmg)2] (H2dmg = dimethylglyoxime) stem from their metal...metal stacked virtually insoluble aggregates. Given virtual insolubility materials, we postulated that rare reports on dissolved species in solution do not represent monomolecular but oligomers. We thus studied structural spectral properties entities these compounds using de...

A new binuclear paddle-wheel palladium(II) complex of [Pd2(μ-mtzt)4]dmgH2 (1) has been prepared by the treatment of PdCl2 in acetonitrile with mixture of 1-methyl-1H-1,2,3,4-tetrazole-5-thiol (Hmtzt) and dimethylglyoxime (dmgH2) in methanol. Resulted complex was characterized by elemental analysis (CHNS), IR, UV–Vis absorption, 1H NMR spectroscopy and its structure was determined with single-cr...

BACKGROUND AND AIMS Nickel (Ni) hyperaccumulation is a rare form of physiological specialization shared by a small number of angiosperms growing on ultramafic soils. The evolutionary patterns of this feature among European members of tribe Alysseae (Brassicaceae) are investigated using a phylogenetic approach to assess relationships among Ni hyperaccumulators at the genus, species and below-spe...

Release of nickel from nickel or nickel-plated metals, is often responsible for allergic contact dermatitis. However, the effect of nickel-bearing stainless steels is not weil known. ln this paper AISI 304, 316 and 430 type stainless steels, as weil as nickel and nickel-plated materials, are investigated. Three tests were carried out: electrochemical tests and leaching experiments in sodium chl...
