The linear, two-coordinate and isostructural heteroleptic [M(IPr){N(SiMe3)2}] (IPr = 1,3-bis(diisopropylphenyl)-imidazol-2-ylidene), formally MI complexes (M = Co, 3; Fe, 4) were obtained by the reduction of [M(IPr)Cl{N(SiMe3)2}] with KC8, or [Co(IPr){N(SiMe3)2}2] with mes*PH2, mes* = 2,4,6-tBu3C6H2. The magnetism of 3 and 4 implies CoII and FeII centres coupled to one ligand-delocalized electr...

The asymmetric unit of the title complex, [Co(NCS)2(C7H9N)2(CH3OH)2], comprises of one CoII cation located on a centre of inversion, one thio-cyanate ligand, one methanol ligand and one 3,5-di-methyl-pyridine ligand. The CoII cation is octa-hedrally coordinated by two terminal N-bonding thio-cyanate anions, two methanol mol-ecules and two 3,5-di-methyl-pyridine ligands into a discrete complex. ...

new hetero-binuclear hg-cu schiff base complexes were prepared by reaction of 2,2'-[1,1'-(2,2-‎dimethylpropane-1,3-diyldinitrilo)-diethyldyne]diphenolato}copper(ii) (cul1) and 6,6'-x-2,2'-[(2,2-‎dimethylpropane-1,3-diyl)bis(nitrilomethanylylidene)]diphenolato copper(ii) [(x = ethoxy (cul2) and ‎methoxy (cul3)], with hgcl2 to give [cu(l1)hgcl2] (1), [cu(l2)hgcl2] (2), and [cu...

Experimental work pertaining to the molecular cytogenetics of malaria vector species of mosquitoes by the application of PCR technique has been carried out. The main objectives of the study included the sequence characterization of nuclear rDNA internal transcribed spacers 1 and 2 (ITS1, ITS2) and mitochondrial DNA COII gene as potential molecular markers for studying genetic relatedness and ph...

The title compound, [Co(C11H8O5)(C8H7N3)] n , which is based on (E)-3-[3-(carb-oxy-meth-oxy)phen-yl]acrylic acid (H2L) and 3-(pyridin-4-yl)pyrazole (pp) ligands, has been synthesized under solvothermal conditions. The dihedral angle between pyrazole and pyridine rings in the pp ligands is 23.1 (2)°. In the crystal, helical chains formed by pp and L ligands connected to the CoII atom propagate p...

Four new NiII, CoII, ZnII, and CuII complexes with the promising anti-tuberculosis drug (E/Z)-N′-((5-Hydroxy-3,4-bis(hydroxymethyl)-6-methylpyridin-2-yl)methylene)-isonicotino-hydrazide (LH) were synthesized characterized by structural methods: single-crystal X-ray diffraction, vibrational spectroscopy, mass spectrometry. The ZnII metal ions form only amorphous phases various morphologies accor...
