Organotin biocides. Part 2. Variable-temperature 119Sn Mössbauer study of phenyl- and cyclohexyl-tin compounds

摘要: The temperature dependence of the recoil-free fraction (a=–d In f/dT) for 13 phenyl- and 11 cyclohexyl-tin compounds has been investigated, results interpreted in terms lattice structures compounds. This interpretation is aided by a classification organotin polymers based upon stereochemical disposition tin bridging groups. Lattices non-interacting units, or which are helical (Class 4) ‘S’-shaped 3), show highest values. value this parameter generally reduced zigzag 2) polymers, while most rigid lattices (lowest a) rod-like 1) architecture.
