tow new compound of type [(chelate)2cu-oh-cu(chelate)2] x3.nh2o, where chelate=1,10-phenanthroline; x=cl¯(n=3.5) and chelate=4,4'-dimethyl-2,2'-bipyridine; (n=5) have been synthesized and their properties investigated. the complexes show room temperature magnetic moment order of 1.0 b.m. per copper atom. the x-band esr spectrum of powdered samples at room temperature shows typical dm=1 transit...
Four copper(II) complexes with the ligands bearing two or three alkylpyridine pendant arms attached to an ethylene diamine framework were isolated in pure form (four-coordinate species as perchlorates, and five-coordinate species as hexafluorophosphates). Three complexes and one tosylated ligand were characterized by X-ray diffraction. In the absence of additional monoor bidentate ligands, line...
Recently, attentions have been taken on the investigations regarding the use of nano-sized compounds in different fields including agricultural sector. Due to the importance of evaluating the fate and operation of nano-particles in plant systems, in this survey, responses of 13 wheat genotypes to the effect of nano-iron chelate fertilizer in the Hoagland solution under the conditions of ordinar...

Mo The polymeric [PdCl(dithiocarbamate)]n complexes, in which the ligand ion is dimethyldithiocarbamate (DMDT), pyrrolidine dithiocarbamate (PyDT, (CH2)4NCS2 ) and sarcosine ethyl ester dithiocarbamate (ESDT, EtO2CCH2N(CH...
We have recently presented evidence that diamine oxidase is rcsponsiblc for a portion of the metabolism of histamine in several species (1, 2). This evidence is largely based on the alteration of histamine metabolism produced by compounds which are known to inhibit diamine oxidase in vitro. The inhibitors used were isonicotinylhydrazine (3) and aminoguanidine. The latter is reported to be the m...
chelating is the chemical process by which a mineral (iron, cobalt, copper, zinc, and manganese) is combined with a mixture of amino acids and peptides. the resulting substances are known as chelates. another descriptive term, proteinates, refers to the amino acid bond. these chelated minerals are thought to be more digestible than nonchelated forms. in other words, chelation makes the minerals...
Background: Since alkaloids are nitrogenous compounds, the availability of nitrogen (N) is expected to play an important role in the biosynthesis and accumulation of alkaloids in plants. Nitrogen has been found to increase the content of alkaloids in some of the medicinal plants. Objective: The aim of this study was to compare the effects of nitrogen bio-fertilizers, conventional nitrogen fe...
to evaluate the effect of foliar application of nano iron chelate and iron chelate fertilizers on morphological traits and essential oil content of holy basil, an experiment was conducted at research farm of department of horticultural, shahid chamran university of ahvaz based on randomized complete blocks design with six treatments and three replications. the treatments were including control,...
