Mössbauer spectroscopy finds nowadays a number of applications in various research fields including biology, physics, planetology, materials science, metallurgy, mineralogy but also chemistry. Indeed, Mössbauer spectroscopy can deliver useful information on electronic properties of matter, structural insights, dynamics and solid-state effects of chemical systems. Most of the time, the new generation of inorganic chemists is not aware of the potentiality of the technique, due to its fast disappearance from chemistry school programs, which is very surprising at the time of artificial intelligence and computer search softwares. It is even considered as a complex physical technique without any meaning for chemists in general. Recently, Garcia, Wang and Zhang took up the challenge to write a book on Mössbauer spectroscopy for chemists, which is proposed to conference participants.1 The book offers a wide range of chemical applications and concepts as well as numerous examples. It will be beneficial to to readers working in different areas of chemistry and material science covered by Mössbauer spectroscopy such as energy (batteries), environment, life sciences, molecular electronics, optoelectronic and thermoelectric applications, catalysis, etc. It is intended to researchers in academia and industry, but also occasional readers and newcomers to the field. In this lecture, I will review several examples of transition metal complexes studied by 57Fe and 119Sn Mössbauer spectroscopy and focus in particular on complexes displaying the spin crossover phenomenon.
Garcia et al. (Wed,) studied this question.
