The Ixodes ricinus complex is composed of 14 species distributed worldwide. Some members of this complex are involved in the transmission of a number of diseases to animals and humans, in particular Lyme borreliosis, tick-borne encephalitis, ehrlichiosis and babesiosis. While the phylogenetic relationships between species of the I. ricinus complex have been investigated in the past, still littl...

Presented herein is a study of the acid-induced demetalation of two sterically hindered copper corroles, Cu β-octabromo-meso-triphenylcorrole (Cu[Br8TPC]) and β-octakis(trifluoromethyl)-meso-tris(p-methoxyphenyl)corrole (Cu[(CF3)8TpOMePC]). Unlike reductive demetalation, which affords the free-base β-octabromocorrole, demetalation of Cu[Br8TPC] under non- reductive conditions (CHCl3/H2SO4) resu...

The formation of [{CoII(teta)2}{CoII2(tren)(teta)2}VIV15SbIII6O42(H2O)]·ca.9H2O [teta = triethylenetetraamine; tren = tris(2-aminoethyl)amine] illustrates a strategy toward reducing the molecular charge of polyoxovanadates, a key challenge in their use as components in single-molecule electronics. Here, a V-O-Co bond to a binuclear Co2+-centered complex and a Sb-N bond to the terminal N atom of...

The CoII-catalyzed [2+2+2] cycloaddition of functionalized diynes and phosphaalkynes resulting in the formation an array structurally interesting phosphinines is reported. A combination 1,2-bis(diphenylphosphino)benzene (dppbenz) CoI2 turned out to be most suitable active catalyst system under microwave reaction conditions. Chemoselective cyclizations presence nitriles have been observed, a num...

The conditions for achieving the maximal unquenched orbital angular momentum L = 3 and highest magnetic anisotropy in mononuclear 3d complexes with axial coordination symmetry are examined terms of ligand field theory. It is shown that, apart from known linear two-coordinate 3d7 complex CoII(C(SiMe2ONaph)3)2 characterized by record single-molecule magnet (SMM) performance (with largest spin-rev...

Die ersten oktaedrisch koordinierten CoII-Komplexe mit redoxaktivem Bisguanidin-Liganden und acac-Coliganden wurden synthetisiert hinsichtlich ihrer Redoxchemie analysiert. N-H-Funktionen in einem partiell alkylierten Guanidino-Gruppen bilden N-H⋅⋅⋅O-Brücken zu den beeinflussen dadurch stark die Redoxchemie. Bei allen Komplexen ist erste 1 e−-Oxidation metallzentriert führt CoIII-Komplexen neut...

In this work, a new cobalt(III) complex, [Co(HEAC)2]ClO4’”2.5H2O (1), with the HEAC, 2(2-(2-hydroxyethylamino)ethylamino)cyclohexanol, was prepared and identified by elemental analysis, FT-IR and UV-Vis spectroscopy, cyclic voltammetry and single-crystal X-Ray diffraction. The cobalt atom in the crystal structure of 1 has a distorted octahedral geometry by coordination of the four nitrogen and ...

DNA sequences of the complete cytochrome b gene are shown to contain robust phylogenetic signal for the strepsirrhine primates (i.e., lemurs and lorises). The phylogeny derived from these data conforms to other molecular studies of strepsirrhine relationships despite the fact that uncorrected nucleotide distances are high for nearly all intrastrepsirrhine comparisons, with most in the 15%-20% r...

The structure of the title compound, [N(C2H5)4]2[Co2(C2N3)5(H2O)4](C2N3), is a new example of a metal-dicyanamide coordination polymer which exhibits a unique three-dimensional framework of covalently linked CoII chains. All bridging dicyanamide ligands in the title structure are in the μ1,5-bridging mode. The anionic CoII-dicyanamide network is templated by tetra-ethyl-ammonium cations residin...
