We fabricated an electrode chip with a structure coated by an insulation layer that contains dispersed SiO(2) adsorbent particles modified by an amino-group on a source-drain electrode. Voltage changes caused by chelate molecule adsorption onto electrode surfaces and by specific cation interactions were investigated. The detection of specific cations without the presence of chelate molecules on...

In the square-pyramidal title complex, [CuCl(C(17)H(24)N(4)O)]Cl, the Cu(II) atom is coordinated by three N atoms [Cu-N 1.946 (2), 2.010 (2), 2.085 (3) Å], one O atom [Cu-O 1.910 (2) Å] and one apical Cl atom [Cu-Cl 2.6437 (9) Å]. The three coordinated N and one O atom are almost coplanar, with a maximum deviation of 0.0268 Å. The tetra-dentate ligand forms two five-membered (N-Cu-N) and one si...

In the centrosymmetric mononuclear title complex, [Cu(C₁₈H₂₀N₂O₂)₂], the Cu(II) atom is four-coordinated in a trans-CuN₂O₂ square-planar geometry with the N-Cu-O chelate angle being 89.97 (11)°. The dihedral angles made by the planes defined by the aromatic ring carbons of the 4-methyl-benzene and 2,4-dimethyl-benzene fragments with the plane defined by the chelate ring are 13.43 (15) and 82.69...

The crystal structure of title compound, [Eu(NO(3))(3)(C(15)H(15)NO(2))(2)], contains two Schiff base 6-meth-oxy-2-[(4-methyl-phen-yl)imino-meth-yl]phenolate (L) ligands and three independent nitrate ions that chelate to the europium(III) ion via the O atoms. The coordination number of the Eu(III) ion is ten. The L ligands chelate with a strong Eu-O(deprotonated phenolate) bond and a weak Eu-O(...
