In the title cobalt(II) compound, [Co(C(12)H(21)N(2)Si)Cl(C(6)H(16)N(2))], the ethane-1,2-diamine donor mol-ecule coordin-ates the metal atom in an N,N'-chelating mode, with Co-N distances of 2.136 (2) and 2.140 (3) Å. An anilide ligand connects to the Co(II) atom with a σ-bond, the Co-N(anilide) distance being 1.931 (2) Å. The four-coordinate Co(II) atom demonstrates a slightly distorted tetra...
A new diphosphine ligand assembled on the cyclotriphosphazene platform forms linear chelate and dimetallic bridged complexes with Au(I) and a cis-chelate complex with Pt(II).
The asymmetric unit of the title compound, C(16)H(12)Cl(4)N(2)O(2), comprises half of a potentially tetra-dentate Schiff base ligand, located about a twofold rotation axis which bis-ects the central C-C bond of the ethane-1,2-diamine group. In the solid state, the compound exists in the zwitterionic form. There are two intra-molecular N-H⋯O hydrogen bonds making S(6) ring motifs. In the crystal...
study of the nuclear magnetic resonance spectra of glyoxaldihydrazone in dimethylsulfoxide and deuterochlorofonn leads to the conclusion that this compound exists predominantly in non-chelate structure
Treating 1,5-difluoro-2,4-dinitrobenzene (1) with N1-phenyl-5-(trifluoromethyl)benzene-1,2diamine (4) and N,N-diisopropylethylamine in EtOH at ca. 0 ◦C for 4 h affords a mixture of N1-(5-ethoxy-2,4-dinitrophenyl)-N2-phenyl-4-(trifluoromethyl)benzene-1,2-diamine (5) (38%) and N1-(5-fluoro-2,4-dinitrophenyl)-N2-phenyl-4-(trifluoromethyl)benzene-1,2-diamine (6) (51%) that can be separated by chrom...
Biological and nano fertilizers are alternative supplements to chemical security for the sustainability of agricultural production. This study is present investigate effect biological on quantitative qualitative yield cow pea during two crop years (2018-2019 2019-2020) in research farm South Agricultural Research Education Center Kerman province, Iran. experiment was carried out factorial desig...
This study describes the effects of the substituents on electrochemical behavior and antioxidant activity of the three tetradentate Schiff bases, containing ethane-1,2- diamine, propane-1,3- diamine and butan-1,4- diamine as the amine part and salicylaldehyde, and corresponding Cd(II) complexes. Cyclic voltammograms of these compounds were recorded in dimethylsulfoxide and 0.1 M sodium perchlor...
in order to study the effect of iron chelate (fe-eddha) on some biochemical characteristic of safflower (carthamus tinctorius l.) under two irrigation regimes, a field experiment was set up a split-plot based on randomized block design with four replication in 2011 in a research field of the faculty of agriculture at shahed university. in this study the main plots consisted of two levels of irr...
INTRODUCTION Intolerance to various foods, excluding bona fide coeliac disease and lactose intolerance, represents a growing cause of patient visits to allergy clinics.Histamine intolerance is a long-known, multifaceted clinical condition triggered by histamine-rich foods and alcohol and/or by drugs that liberate histamine or block diamine oxidase (DAO), the main enzyme involved in the metaboli...
