Mesostructured chalcogenide-based materials with long-range order and semiconducting properties can be prepared using suitable molecular building blocks, linkage metal ions and surfactant molecules. In this paper we present surfactant templated, open framework platinum tin selenide and telluride materials assembled using K4SnQ4 (Q = Se, Te) salts and K2PtCl4 as precursors and a study of pore an...

The melt-phase synthesis of dioctyltin (IV) and triphenyltin (IV) benzoates were carried outusing stoichiometric amounts of benzoic acids and the corresponding organotin (IV) compounds.The reagents were ground together in a mortar and fed into a boiling glass tube. A cannula tubewas inserted into the boiling tube to discharge accumulated gaseous products. A syringe ensureda continuous flow of d...

Seven organotin compounds and tin chloride were tested for their effects on the methanogenic bacteria Methanococcus thermolithotrophicus, Methanococcus deltae delta LH, and Methanosarcina barkeri 227. The methanogens were strongly inhibited by triethyltin, tripropyltin, and monophenyltin compounds, generally at concentrations below 0.05 mM. Less inhibition by tributyltin and diphenyltin was obs...

Cyclic voltammetric surface waves were found for monolayers of Ru(bpy)Z(bpyY+, where bpy’ is 4-methyl4’-(dodecyl-l-thiol)-2,2’-bipyridine, which spontaneously adsorbs onto conducting substrates (indium tin oxide, polycrystalline gold). On polycrystalline gold, the monolayer, probably attached via the thiol functional group, is oxidized in an aqueous oxalate medium to produce electrogenerated ch...

Reaction of three hexadentate ligands (L1eL3) derived from 1,4-benzoquinone bis(aminoalcohols) with diorganotin oxides (R2Sn-O)n (with R 1⁄4 Me, nBu, Ph) in 1:2 stoichiometric proportions lead to the formation of dinuclear tin compounds of the composition [(R2Sn)2(L)], wherein the five-coordinate metal centers are embedded in distorted trigonal-bipyramidal polyhedra. X-ray diffraction analysis ...

The solution-based synthesis of nanoscale earth-abundant semiconductors has the potential to unlock simple, scalable, and tunable material processes which currently constrain development of novel compounds for alternative energy devices. One such promising semiconductor is zinc tin phosphide (ZnSnP2). We report the synthesis of ZnSnP2 nanowires via a solution-liquid-solid mechanism utilizing me...

Flavonoids are plant secondary metabolites that insure the proper growth, development and protection of plants. Both in vivo and in vitro, they exhibit a broad biological activity that in many cases is connected with their antioxidative ability. The diversified ring structure of a flavonoid molecule with conjugated double bonds and numerous hydroxyl substituents ensures their antioxidative acti...

In the preceding paper we reported the discovery of a tin(1v) derivative obtained by intermolecular oxidative addition to an organotin(m) species.' In the present paper we give details of the synthesis of a tetra-alkenylchromium(1v) complex starting from a chromium(r1r) species, and of the analogous tin(1v) compound obtained from SnCI, by simple metathetical exchange. The X-ray data provide an ...

The biochemical transformation of mercury, tin, arsenic and bismuth through formation of volatile alkylated species performs a fundamental role in determining the environmental processing of these elements. While the toxicity of inorganic forms of most of these compounds are well documented (e.g., arsenic, mercury) and some of them are of relatively low toxicity (e.g., tin, bismuth), the more l...
