Photocatalytic Syngas Production In article number 2200085, Mingxiong Lin, Zanyong Zhuang, Yan Yu, and co-workers report the construction of an ordered CoIII[email protected]II-MOF heterostructure based on a spontaneous oriented attachment mechanism. CoIII-PBA exerts stronger affinity for CO2 molecules than CoII-PBA, thus serves as active sites, built-in electric field in protected]II-PBA heter...

The present study explored the intraspecific genetic diversity, dispersal patterns and phylogeographic relationships of Culex quinquefasciatus Say (Diptera: Culicidae) in Malaysia using reference data available in GenBank in order to reveal this species' phylogenetic relationships. A statistical parsimony network of 70 taxa aligned as 624 characters of the cytochrome c oxidase subunit I (COI) g...

The asymmetric unit of the title compound, [Co(NO3)2L] n , L = N-(pyridine-2-ylmeth-yl)pyridine-3-amine (C11H11N3), contains one CoII centre, two nitrate anions and one L ligand in which the Cpy-C-N-Cpy moiety adopts a trans conformation with a torsion angle of -173.1 (3) Å. The coordination geometry of the CoII atom is a distorted penta-gonal bipyramid. One amine N atom from the L ligand and f...

Mechanically chelating ligands have untapped potential for the engineering of metal ion properties. Here we demonstrate this principle in context CoII-based single-ion magnets. Using multi-frequency EPR, susceptibility and magnetization measurements found that these complexes show some highest zero field splittings reported five-coordinate CoII to date. The predictable coordination behaviour in...

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. ...

first row transition metal complexes of phthalocyanine are employed as catalysts for the oxidation of cyclohexene and cyclooctene using iodosylbenzene and pentafluoroiodosyl benzene. the catalysis was performed in dichloromethane: methanol:water (80:18:2) solvent mixture.  the products of the catalysis for cyclohexene are epoxycyclohexane, 2-cyclohexene-1-ol and 2-cyclohexene-1-one whereas for ...

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...

Reaction of bis-(pyridin-3-ylmeth-yl)sulfane (L) with cobalt(II) chloride in methanol led to the formation of the title coordination polymer, [CoCl2(C12H12N2S)(CH3OH)2] n , in which the CoII cation lies on a crystallographic inversion centre and the S atom of the L ligand lies on a twofold rotation axis. Each CoII ion is coordinated by two pyridine N atoms from two bridging L ligands, two O ato...
