Synthesis, structure, and spectroscopic properties of copper(II) compounds containing nitrogen–sulphur donor ligands; the crystal and molecular structure of…
The linear quadridentate N2S2 donor ligand 1,7-bis(N-methylbenzimidazol-2′-yl)-2,6-dithiaheptane (bmdhp) forms mono- and di-hydrate 1 : 1 copper(II) complexes which are significantly more stable…
Conversion constants for redox potentials measured versus different reference electrodes in acetonitrile solutions at 25°C
Abstract Caution should be exercised when one is comparing the redox potentials of complexes measured in CH 3 CN solutions versus different reference electrodes. A critical review of conversion…
Nitrosyliron(III) hemoglobin: autoreduction and spectroscopy.
Nitrosyl complexes of the iron( III) forms of myoglobin, human hemoglobin, Glycera dibranchiata hemoglobins, and model iron(II) and iron(III) synthetic porphyrins including octaethylporphyrin (OEP) have been prepared and kinetic and spectroscopic evidence shows involvement of trans-heme-(NO)2 in the reaction.

Spectroscopic and redox studies of some copper(II) complexes with biomimetic donor atoms: implications for protein copper centres
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…
Copper complexes of the "tripod" ligand tris(2-benzimidazolylmethyl)amine: five- and six-coordinate copper(II) derivatives and some copper(I) derivatives
Structure of trimeric haemerythrin
The pattern of intersubunit helix–helix interactions differs from the most common mode of association of other helix-bundle proteins, and a novel approach to structure analysis at low resolution is reported.
A Triple‐Decker Heptadecanuclear (CuII)15(CrIII)2 Complex Assembled from Pentanuclear Metallacrowns
Reaction of the pentanuclear Cu II metallacrown [Cu 5 (ahpha) 4 ]-(ClO 4 )·4H 2 O (ahpha 2- is the dianion of 3-amino-3-(hydroximino)propanehydroxamic acid), with Cr(C 2 O 4 ) 3 3- led to the…

Ruthenium myoglobins have been prepared by the reconstitution of horse heart apomyoglobin with either rUThenium(II) or ruthenia(III) mesoporphyrin IX (MpIX) derivatives, which are readily interconverted using dithionite for reduction and bromine for oxidation.
