Copper dithiocarbamates

In many complexes, mixed oxidation states for the transition metals are found. Complex (41) is a diamagnetic compound with the actual composition (42).68 Copper dithiocarbamates are synthesized not only with copper in the oxidation states I, II or III but also with the metal in mixed oxidation states III and I (43, 44, 45), II and I (46, 47) and even III and I [48, 49).56 Complex (50), which has two isomeric structures a and / , has Ru either in a trapped oxidation state II,in or in a delocalized oxidation state of 2.5. The /J-isomer is the most stable.69 Slow, controlled potential electrochemical oxidation of (51) yields (52), in which the metal has a trapped oxidation state II,HI.70... 

They can react with metal-containing enzymes (e.g., polyphenoloxidase and ascorbic acid oxidase) to form a copper-dithiocarbamate complex with high fungicidal activity (thiram and ziram probably owe their fungicidal activity to this type of reaction). 

Alkylindium thiolate complexes readily react with copper dithiocarbamate compounds to yield binuclear complexes, according to Scheme No structural data is available for these mixed metal complexes however, they have been... 

The solubilities of chelates with palladium, rhodium, lead and copper have been measured with static and dynamic spectroscopic methods at different temperatures and different pressures. The influence of different ligands, ligand modifications and of the metal ions coordination sphere on the solubility were studied and compared to the influence of pressure and temperature of the supercritical carbon dioxide (scCOa). In a series of C2, C4, Ce, Cg copper dithiocarbamates a maximum solubility was measured with the butyl substituents.

Structurally related compounds, dithiocaibamates (XIV), have fungicidal activity. Reversed-phase chromatography of copper dithiocarbamates was studied, and the Revalues were found to be linearly dependent on the chain length of the chelate, the water content of the mobile phase, and the number of carbon atoms of the chemically bonded stationary phase (93). 

In other work, vibrational shifts for nickel and copper dithiocarbamate complexes have been correlated with those observed for atomic core levels in the X-ray photoelectron spectra (523), and an experimental procedure is detailed for the collection of high-quality IR spectra from metal dithiocarbamate singlecrystal surfaces using polarized radiation and attenuated total reflectance (524).
