    The nuclear magnetic resonance spectra of a series of methyltin halides containing 13 C, Sn, and Sn in natural abundance have been measured. In all cases the reduced coupling constant K( Sn– 13 C) is positive, and K( Sn– 1 H) is negative. There is an approximately linear correlation between J( Sn– 13 C) and J( Sn– 1 H) but the form of the relationship indicates that. ORGANOTIN (Methyl and Butyl) TOXICITY Occurrence Tin (Sn) is a silver metal (atomic number 50) that occurs in the earth's crust mainly as cassiterite or tinstone (SnO2) which is the main source of tin production (1). The toxicity of inorganic tin after inhalation and ingestion is low. Absorbed tin is mostly stored in bone and excreted via urine (1).File Size: 28KB.

    Tin(IV) chloride, also known as tin tetrachloride or stannic chloride, is an inorganic compound with the formula Sn Cl is a colorless hygroscopic liquid, which fumes on contact with is used as a precursor to other tin compounds.

    C. Esser, in Comprehensive Medicinal Chemistry II, Organotin compounds. Organotin compounds are chemicals with at least one covalent Sn–C bond. They are widely used as polyvinyl chloride (PVC) stabilizers, biocides, or antifouling paints and have given rise to ubiquitous environmental contamination. 87 They are known to be immunotoxic, to induce thymus atrophy in. 11 Organotin Halides 12 Organotin Hydroxides and Oxides 13 Organotin Carboxylates and Other Oxyesters 14 Organotin Alkoxides, Phenoxides, and Peroxides 15 Organotin Hydrides 16 Compounds with Sn-N Bonds 17 Compounds with Sn-S Bonds 18 Compounds with Sn-Sn Bonds 19 Compounds with Tin-metal Bonds 20 Organotin Radicals and Radical Ions.

The halide derivatives, R 3 SnX, often contain Sn Organotin Compounds book bridges and form chain structures.

The presence of bulky R groups may affect the shape. For example, in (SnFMe 3) n, the Sn-F-Sn backbone is in a zigzag arrangement, in Ph 3 SnF the chain has straightened, and (Me 3 SiC)Ph 2 SnF is a monomer. The haloalkyls are more reactive than the tetraalkyls and are useful in the synthesis of.

organotin (IV) compounds are simple, tetrahedral molecules containing 4-coordinate tin atoms., however, the w ell-established techniques of proton NMR and infrared spectroscop y have beenAuthor: Emad Yousif.

After the organotin compounds (OTCs) are prepared, they are usually characterized by using IR, NMR (1 H NMR, 13 C NMR, Sn NMR) and Mossbauer spectroscopies. Sn NMR spectroscopy:File Size: KB. The four principal classes of organotin(IV) compounds are mono- di- tri- and tetraorganotins, which are represented by RnSnX4-n (n=), where R is any organic group and X is anionic residue.
