Clearing metallation

The enzymes that utilize molybdenum can be grouped into two broad categories (1) the nitrogenases, where Mo is part of a multinu-clear metal center, or (2) the mononuclear molybdenum enzymes, such as xanthine oxidase (XO), dimethyl sulfoxide (DMSO) reductase, formate dehydrogenase (FDH), and sulfite oxidase (SO). The last... 

Typically, various sized LDH particles are synthesized under hydrothermal conditions by altering the aging time and reaction temperature. A clear metal solution was prepared with concentration 0.1 M, and the ratio of Mg A1 fixed at 2 1. The clear solution was titrated up to pH 9.5 with 0.5 M of NaOH solution containing Na2C03, and samples were then aged in an autoclave at various temperatures for various... 

The octahedral complexes, pale green [VmL], purple VlvL]PF6, and blue-black [VvL](C104)2, where L represents a l,4,7-tris(2-hydroxybenzyl)-l,4,7-triazacyclononane derivative, serve as an example where all one-electron redox processes are clearly metal centered as depicted in Eq. (6). Table III lists the complexes prepared (148b, 152, 153). 

EH-SCCC-MO calculations on the diamagnetic polythiometalates M3XSg (X = O, S) also show that these can be described as coordination compounds of MIVX2+ with MS4- ligands. For instance, an occupied MO is about 50% localized on the central W atom, but owing to the appreciable (ca. 20%) participation of the outer orbitals of W atoms there is a clear metal-metal interaction comparable to the M -TM interaction in heteronuclear systems (TM = thiometalate).]... 

P, As, Sb) and P -Et2Me2Z (Z = P, As, Sb) salts of Pd(dmit)2 with the formal charge of 1/2-, the conduction band is considered the HOMO band [42]. All these salts show no clear metallic behavior at ambient pressure. Susceptibility, ESR,... 

Clearly, metal-containing polymers represent an important emerging field. We look forward to further rapid progress in the next decade. 

Reduction of the tris-diimin complex Rh(bpy) + takes place in a completely irreversible two-electron step, whereas all Rh(CAN)2(NAN)+ and the corresponding Ir complexes show one or more reversible one-electron reductions. In the former case, the reduction is clearly metal centered,... 

Section III.B illustrated the complex and unusual structures that can be generated from the different binding modes of metal-alkyne constructs. Clearly, metal-alkyne Jt-complex chemistry is rich and in some ways has a distinct... 

The ultimate choice of the application method itself will further be determined by an analysis of many factors. Whether the material to be applied is solid, liquid, or powdered thick or thin clear, metallic, or wrinkled or waterborne or oil based are all... 

Aluminum and its congeners, Ga, In and Tl, are considerably larger than boron and hence they are much more metallic and ionic in their character. Elemental aluminum itself is clearly metallic, but it is nevertheless still on the borderline (like beryllium) between ionic and covalent character in its compounds. So also are Ga, In and Tl. 

A range of heteronu clear metal-metal bonded dimeric porphyrin complexes have also been prepared. ... 

Controlled-potential coulometry may be applied to the analysis of a wide variety of substances. Clearly, metals like copper could be deposited and determined without the necessity of weighing the electrode. More importantly, mercury electrodes can be used and thus most of the metals more difficult to reduce can be determined. Also, it is possible to apply coulometry to systems in which both oxidized and reduced forms are soluble, such as determining iron by reducing iron(III) to iron(II). Anions such as chloride or bromide may be converted to AgCl or AgBr by deposition on a silver anode.
