The title compound, [Cu(C(16)H(32)N(4))](C(14)H(14)O(2)PS(2))(2) or [Cu(trans[14]dien)][S(2)P(OC(6)H(4)Me-4)(2)](2), where trans[14]dien is meso-5,7,7,12,14,14-hexa-methyl-1,4,8,11-tetra-azacyclo-tetra-deca-4,11-diene, was obtained by the reaction of [Cu(trans[14]dien)](ClO(4))(2) and [(C(2)H(5))(2)NH](2) [S(2)P(OC(6)H(4)Me-4)(2)](2). The Cu(II) atom lies on a centre of inversion and possesses ...

Cisplatin (cDDP) is known to bind to the CXXC motif of proteins containing a ferrodoxin-like fold but little is known about its ability to interact with other Cu-binding proteins. MEK1/2 has recently been identified as a Cu-dependent enzyme that does not contain a CXXC motif. We found that cDDP bound to and inhibited the activity of recombinant MEK1 with an IC50 of 0.28 μM and MEK1/2 in whole c...

A new, highly selective and sensitive colorimetric chemosensor 1 for detection of Cu(2+) ions in aqueous solution was developed. Receptor 1 detected Cu(2+) ions by changing its color from colorless to yellow. Moreover, the Cu(2+)-sensitive compound was used as a colorimetric pH detector based on a color change due to 1-Cu(2+) complex formation identifiable by the naked eye.

The title compound, (C(21)H(22)P)(2)[Cu(2)I(4)], prepared from reaction between copper powder, iodine and isopropyl triphenyl-phospho-nium iodide in hydroxy-acetone (acetol), shows an already known Cu(2)I(4) (2-) anion with a planar conformation [Cu-I range = 2.5108 (3)-2.5844 (3) Å and I-Cu-I range = 110.821 (10)-125.401 (10)°].

In the title compound, {[Cu(II)Cu(I) (2)(C(5)H(3)N(2)O(2))(2)(CN)(2)(H(2)O)(2)]·2H(2)O}(n), the Cu(II) atom lies on an inversion centre and is octa-hedrally coordinated by two N atoms and two O atoms from opposing pyrazine-2-carboxyl-ate (2-pac) ligands and two water O atoms. The Cu(I) atom has a triangular geometry, coordinated by one N atom and one C atom from two bridging cyanide ligands, an...

An environmentally benign antisolvent method has been developed to prepare Cu(2+)-doped ZnO nanocrystals with controllable dopant concentrations. A room temperature ionic liquid, known as a deep eutectic solvent (DES), was used as the solvent to dissolve ZnO powders. Upon the introduction of the ZnO-containing DES into a bad solvent which shows no solvation to ZnO, ZnO was precipitated and grow...

In the title compound, [Cu(2)(C(7)H(5)O(2))(4)(C(10)H(9)N)(2)], the paddle-wheel-type dinuclear complex mol-ecule contains four bridging benzoate groups and two terminal 3-methyl-quinoline ligands. The asymmetric unit contains one and a half mol-ecules with a total of three independent Cu atoms; there is an inversion center at the mid-point of the Cu⋯Cu bond in one molecule. The octa-hedral coo...

2-(methylamino) pyridine (hmap) reacts with meli in thf and generates the lithium salt (limap). further reaction of [cu(tmeds)2][cucl2] (tmeda=tetramethylethylenediamine) with one equivalent of this ligand in thf leads to the formation of a yellow dimeric cu(i) complex, [cu(map)]2. analytical data, molecular weight, and magnetic susceptibility measurements, confirm the formula [cu(map)]2 .

An environmentally benign Cu-Ce-Ti oxide catalyst exhibited excellent NH3-SCR activity, high N2 selectivity and strong resistance against H2O and SO2 with a broad operation temperature window. The dual redox cycles (Cu(2+) + Ce(3+) ↔ Cu(+) + Ce(4+), Cu(2+) + Ti(3+) ↔ Cu(+) + Ti(4+)) play key roles for the superior catalytic deNOx performance.
