Both biologically active and autoclaved sediments convert trimethyltin hydroxide to the volatile tetramethyltin. Larger amounts of tetramethyltin were formed in the bioactive sediments than in the sterile sediments. No volatile tin compounds were detected in the absence of trimethyltin hydroxide or from trimethyltin hydroxide in seawater or in seawater containing bentonite. The formation of tet...

Ab s t r a c t . The effect of organic-metallic compounds including lead, (C6H5)3PbCl, and tin, (C6H5)3SnCl, on cucumber leaves and green algae Scenedesmus quadricauda were studied. Both compounds, in concentration of 2 μmol dm, caused increased emission of ultra weak chemiluminescence (UCL) of cucumber leaf discs after 20 hours of treatment, and activity of tin triphenyl chloride was stronger ...

The series of 14 complex organotin(IV) compounds containing many tin atoms and noncovalent bonds in the structure was characterized by electrospray ionization multistage tandem mass spectrometry (ESI-MS(n)). The mass spectra were measured in both polarity modes to obtain complementary structural information. The characteristic pattern of ten natural tin isotopes allowed the determination of the...

The title compounds were prepared by direct reactions of the corresponding elements at high temperature. They are isostructural with each other (monoclinic, P2(1)/m, Z = 2; Na(8)BaPb(6), a = 13.116(4), b = 5.351(1), and c = 16.166(5) A, beta = 108.07(2) degrees; Na(8)BaSn(6), a = 12.897(4), b = 5.362(1), and c = 16.826(5) A, beta = 108.19(2) degrees; Na(8)EuSn(6), a = 12.912(2), b = 5.220(1), a...

The industrial production of alkyl tin derivatives has increased rapidly in recent years, but little is known about the hazards to man which may exist in the handling of these substances. Interest in the matter has been sharpened by the catastrophic results of a therapeutic trial of one of the group, diethyl tin di-iodide, in the treatment of furunculosis. The compound was given orally and caus...

Organometallic compounds are widely used in almost all sectors of industry. as a result of emissions from natural and anthropogenic sources they are released to the environment, where they undergo a variety of conversions and interactions. some organometallic compounds exhibit high toxicity. organometallic compounds of mercury, tin, lead, selenium and arsenic are among the most common and hazar...
