Summary
The dependence of the logarithm of the area under the tin-119 Mössbauer resonance (A at different temperatures are normalized toA 77) vs. temperature is measured for tetrachloro[1,4-di(p-methoxyphenyl)-2,3-dimethyl-1,4-diazabutadiene] tin(IV). The slope of the plot of lnA vs.T is −2.46·10−2K−1, suggesting a monomeric structure. In the vibrational spectra the significant stretching vibrations agree with acis octahedral configuration of C2v symmetry.
Zusammenfassung
Die Abhängigkeit des Logarithmus der Fläche unter der Zinn-119-Mössbauer-Resonanz (A in verschiedenen Temperaturen werden zuA 77 normalisiert) von der Temperatur wurde für Tetrachlor[1,4-di(p-methoxyphenyl)-2,3-dimethyl-1,4-diazabutadien]zinn(IV) gemessen. Der Anstieg lnA gegenT von −2.46·10−2K−1 spricht für eine monomere Struktur. In den Vibrations-Spektren stimmen die wichtigsten Dehnungsschwingungen mit einercis-oktaedrischen Konfiguration von C2v-Symmetrie überein.
