Spectroscopic and redox studies of some copper(II) complexes with biomimetic donor atoms: implications for protein copper centres

Abstract
The redox chemistry and e.s.r. spectra of a number of copper(
II
) complexes with nitrogen- and sulphur-donor ligands have been examined, including complexes with 2,2′-bi-imidazole, histamine, and cyclic and acyclic saturated amine and thioether ligands. The tetrahedral Cu
II
S
4
centre generated by
γ
-irradiation of single crystals of a thioacetamide complex of Cu
I
has a low value of |
A
|. Tetrahedral distortion of otherwise tetragonal copper(
II
) centres increases
g
and decreases |
A
| for
N
-,
S
-, and
O
-donor ligands, and is a more effective source of reduction of |
A
| than charge effects. The quotient
g
/|
A
| appears to be a convenient empirical index of distortion of the donor set from planar toward tetrahedral, indicating that most type I copper in proteins is tetrahedrally, rather than tetragonally, co-ordinated.
