Reaction/complex formation between copper and sulfur molecules (thiol, polysulfide, etc...)

[n2mp]

Hello everyone,

I'm looking for information about how copper ions (either CuII or Cu I) can
bond with sulfur containing organic molecules (like thiols or polysulfides)
in aqueous medium. Chemical Abstracts gave me either too much references or
totally out of subject answers...
I've seen on the web some self assembled complexes between copper and big
organic molecules, but I wonder if the corresponding molecules were in an
anionic form or if their sulfur atom was bonding copper with its 3p
electron pair while the molecule remain neutral (dative bond). What about
small molecules ?
I also heard about some relationship between electronic structure of
transition metal and their catalytic activities on organic molecule, due to
related respective adsorption properties. What about this for copper/sulfur
containing molecule bonding ?
Any related reference would help.
Thanks by advance.

Best regards.

yes

no difference. CuSO4 6H2O actually has 6 water molecules coordinated
to the Cu atom via a pair of electrons on the water's O atom.

look up coordination chemistry in any inorganic textbook for a
complete rundown.

this is somewhat more advanced inorganic chemistry, along with
physical transport processes. catalysis is a science unto itself.

what? to form CuS? that would be a very favored reaction. if you
are talking about coordination bonding of, say, methionine to Cu, that
would fall under different reaction kinetics.

hit the textbooks.
