Using density functional theory calculations of periodic slabs, within the generalised gradient approximation, this study provides optimised structures for all plausible terminations of copper(II) chloride surfaces along the three low-index orientations. The ab initio atomistic thermodynamic approach serves to construct a thermodynamic stability diagram for CuCl2 configurations as a function of...

The tumor-inhibitory jxitency of combinations of the cupric chelate of kethoxal bis(thiosemicarbazone) [Cu(II)KTS] with several compounds that cause inhibition of the synthesis of DNA by different biochemical mechanisms was assessed in Sarcoma 180 ascites cells. Cu(II)KTS prolonged the survival time of tumor-bearing mice, whereas neither cupric chloride, copper stéarate,nor kethoxal bis(thiose...

In the mol-ecular structure of the title compound, [CuCl(C(6)H(5)NO)(4)]Cl, the Cu(II) atom is coordinated by four N atoms of four pyridine-4-carboxaldehyde ligands and one chloride anion in a slightly distorted square-pyramidal coordination geometry. There is also a non-coordinating Cl(-) anion in the crystal structure. The Cu(II) atom and both Cl atoms are situated on fourfold rotation axes. ...

The title complex, [CuCl(C(15)H(11)N(3))(H(2)O)]Cl·H(2)O, is composed of a monocation that possesses mirror symmetry. The Cu(II) atom has a distorted square-pyramidal geometry, being coordinated by the three N atoms of the terpyridine ligand and a Cl atom in the equatorial plane, and by a water mol-ecule O atom in the axial position. The charges are balanced by a chloride anion positionally dis...

The title tetra-nuclear complex, [Cu(4)Cl(6)O(C(13)H(11)N(3))(4)], features a tetra-hedral arrangement of copper(II) ions bonded to the central O atom (site symmetry [Formula: see text]). Each of the six edges of the Cu(4) tetra-hedron is bridged by a chloride ion (one of which has site symmetry 2), so that each copper ion is linked to the other three metal ions through the central O atom and t...

BMJ 1991;302:88-9 Oral rehydration solutions are highly effective for treating most patients with dehydration due to diarrhoea. Early formulations contained glucose and three salts: sodium chloride, sodium bicarbonate, and potassium chloride. Subsequently, a formulation containing trisodium citrate dihydrate instead of sodium bicarbonate was shown to be more stable under high humidity and tempe...

Copper effects on human health represent a relevant issue in modern nutrition. One of the difficulties in assessing the early, acute effects of copper ingested via drinking water is that the taste of copper may influence the response and the capacity to taste copper in different waters is unknown. The purpose of the study was to determine the taste threshold of copper in different types of wate...

The synthesis of different tetrahydroisoquinolines using choline chloride : ethylene glycol as a deep eutectic solvent (DES) and copper(II) oxide impregnated on magnetite as a catalyst has been accomplished successfully. The copper catalyst amount is the lowest loading ever reported. The presence of DES showed to be essential since the reaction in the absence of this medium did not proceed. A d...
