(−)-Sparteine copper(II) diacetate
Acta Crystallographica Section C Crystal Structure Communications, 2000The 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, 1959STABILITY 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 in photosystem II: association with LHC II
Photosynthesis Research, 1987Photosystem II particles from spinach and barley contained 2.5 and 4.2 Cu per 300 chlorophylls respectively. This Cu was resistant to removal by EDTA. A large percentage of the PSII Cu in both plants is associated with the light-harvesting chlorophyll a/b protein, LHCII; 46% in barley and 76% in spinach.

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 ...

The Journal of Physical Chemistry, 1989
Both the torsion-effusion technique and high-temperature mass spectrometry were used to study the thermal decomposition of the copper sulfate and oxysulfate phases CuSO{sub 4} and CuO {times}CuSO{sub 4} at about 700-780 K. The decomposition processes are retarded kinetically; SO{sub 3} is the primary gaseous product, rather than the dominant ...

Heterobinuclear copper(II)-zinc(II) complexes and their homobinuclear dicopper(II) counterparts (1-4) of two asymmetric ligands (H2L1 and H2L2), based on 2-aminocyclopent-1-ene-1-dithiocarboxylate, are reported. The ligands are capable of providing both donor set and coordination number asymmetry in tandem.

Abstract This article presents the results of laser-assisted metallization of polyurethane coatings containing 5 wt.% of Cu(acac) 2 and 15 wt.% of copper(II) oxide (CuO) or copper(II) hydroxide (Cu(OH) 2 ). Thus, two different coating compositions were compared with regard to becoming active after laser irradiation for direct electroless ...
