In the title complex, [Cu(C(18)H(14)NO)(2)], the Cu(II) ion lies on a crystallographic inversion centre and is bonded to the O- and N-donor atoms of the two bidentate chelate 1-[(o-tol-yl)imino-meth-yl]-2-naphtho-late ligands in a trans arrangement. The distorted square-planar geometry about Cu(II) has normal dimensions, with Cu-O = 1.8881 (15) Å and Cu-N = 1.9804 (17) Å.

In the title complex, [Ni(C(6)H(7)N(2)S)(2)(CH(4)N(2)S)(2)], the central Ni atom (located on a centre of inversion) is six-coordinated by two monoanionic N,S-chelating 4,6-dimethyl-pyrimidine-2-thiol-ate ligands and two trans S-coordinating thio-urea groups. The trans-N(2)S(4) donor set defines a distorted octa-hedral geometry.

The title Schiff base complex, [V(C(13)H(7)BrClNO(2))(CH(3)O)O(CH(3)OH)], features a vanadyl group, a tridentate Schiff base ligand, and coordinated methanol and methano-late ligands. The NO(5) donor set is based on a distorted octa-hedron. Helical supra-molecular chains along [010] are found in the crystal structure mediated by O-H⋯O hydrogen bonds formed between the coordinating methanol mol-...

(N(nBu)4)[MIIIL(acac)2], M = Y, Gd, Tb and Dy, have been constructed by combination of two O donor ligands, bidentate acetylacetone tetradentate p-tert-butylcalix[4]arene.

Heme proteins can perform a variety of electrochemical functions. While natural heme proteins carry out particular functions selected by biological evolution, artificial heme proteins, in principle, can be tailored to suit specified technological applications. Here we describe initial characterization of the electrochemical properties of a de novo heme protein, S824C. Protein S824C is a four-he...

Supramolecular main group chemistry is a developing field which parallels the conventional domain of metallo-organic chemistry. Little explored building blocks in this area are metal-based ligands have appropriate donor symmetry to build desired molecular or extended arrangements. Tris(pyridyl) (E(py)3, E=main metal) potentially highly versatile since shifting N-donor arms from 2- 3-positions a...

We measured the kinetics of U(VI) reduction by Shewanella oneidensisMR-1 under anaerobic conditions in the presence of variable concentrations of either EDTA or dissolved Ca. We measured both total dissolved U and U(VI) concentrations in solution as a function of time. In separate experiments, we also measured the extent of U(VI) adsorption onto S. oneidensis in order to quantify the thermodyna...
