A hexaicosametallic copper(ii) phosphonate

Dalton Transactions, 2013
Structure and characterization of [Cu26{2,3,5,6-(Me)4C6H-CH2-PO3}18(μ2-OH)4(μ3-OH)6(μ4-Cl)6(μ-OH2)2(OH2)2(MeCN)4]·6MeCN·15H2O (1) is reported. Complex 1 is the largest discrete molecular homometallic transition metal phosphonate assembly. Remarkably, this gigantic molecular phosphonate has been prepared at room temperature using a normal solution ...

A hexadecameric copper(II) phosphonate

Dalton Transactions, 2009
The first example of a hexadecanuclear copper(II) phosphonate containing pyrazole, hydroxide and acetate ancillary ligands has been assembled in a reaction involving copper(II) nitrate, pyrazole, t-butylphosphonic acid and triethylamine.

Antilupus activity of copper (II)

Experimental pathology, 1985
Collagen-like syndrome was induced in rats by oral hydralazine administration during 5 months. After 4 months, a subgroup of rats was shifted from the standard diet to the diet supplemented with copper (II) (60 micrograms of copper per g of pellet) as copper sulphate. A decreased serum copper concentration was noted, LE cells were observed in the blood

Thermal studies of copper(II) fumarate and copper(II) terephthalate

Thermochimica Acta, 2005
Abstract Copper(II) fumarate (Cu(OOCC2H2COO)) and copper(II) terephthalate (Cu(OOCC6H4COO)) have been synthesized. Their heat capacity has been measured by adiabatic calorimetry between 13 and 300 K and their magnetic susceptibility determined with a SQUID magnetometer between 5 and 300 K.

(−)-Sparteine copper(II) diacetate

Acta Crystallographica Section C Crystal Structure Communications, 2000
The chiral nitrogen-chelating alkaloid (−)-sparteine acts as a bidentate ligand, reacting with copper(II) acetate in ethanol to form the title complex, [Cu(CH3COO)2(C15H26N2)], with the two acetate groups occupying the remaining coordination sites in a monodentate fashion to produce a distorted four-coordinate tetrahedral structure.

Histidine-Copper (II) Complexes

Nature, 1959
STABILITY constants are known for copper complexes of most of the naturally occurring α-amino-acids. However, although it is of considerable biochemical interest, the copper–histidine system has not been interpreted in detail. The system is anomalous, probably because, although the metal can co-ordinate to the amino, imidazole or carboxyl groups in ...

Copper(II) PMDTA and copper(II) TMEDA complexes: precursors for the synthesis of dinuclear dicationic copper(II) complexes

Inorganica Chimica Acta, 2005
Abstract Copper(II) cations coordinated with PMDTA (pentamethyldiethylenetriamine) and TMEDA (tetramethylethylenediamine) possess a high synthetic potential. The synthesis of these cations was carried out by metathesis reactions with silver salts. The cationic copper(II) complexes, [Cu(PMDTA)(Me2CO)Cl]+, [Cu(PMDTA)(H2O)Cl]+, [Cu(PMDTA)(DMF)]+, [Cu ...
