最近报道的两种锡配合物，在其结构中同时包含Sn(I)和Sn（III）位点，已经通过温度依赖119Sn Mössbauer效应（ME）光谱进行了研究。两个位置的不同的超精细参数使得根据从ME光谱中提取的无反冲分数数据可以分配两个位置（在90k时）的相对占位率。由ME谱分析得到的无反冲组分的温度依赖性表明，在90℃范围内，两个位置的金属原子动力学非常相似
Two recently reported tin complexes, which incorporate both Sn(I) and Sn(III) sites in their structure, have been examined by temperature-dependent 119Sn Mössbauer effect (ME) spectroscopy. The distinct hyperfine parameters of the two sites make it possible to assign relative occupancies of the two sites (at 90 K) on the basis of the recoil-free fraction data extracted from the ME spectra. The temperature dependencies of the recoil-free fractions, elucidated from the ME spectra, show that the metal-atom dynamics are very similar for the two sites in the temperature range 90
