Acknowledgements

Many has supported for finishing my thesis, and I feel this is the right occasion to heartfully thank them.

Wesley, thanks a lot for your great support and motivation throughout my PhD. We had critical discussions not only on science, but also on philosophy. I had lot of fun during the practise talks for the presentations. I mostly enjoyed the dedication and enthusiasm you have shown towards science, and you also have shown me how to think more as a spectroscopist. Still the phrase you repeat again and again absence of evidence is not evidence for absence is highly useful and thought provoking.

I thank my reading committee members Prof. Edwin Otten, Prof. Gerard Roelfes, Prof. Bert Klein Gebbink for your nice words and comments on my thesis.

I thank Edwin for his support to solve the X-ray crystal structures and for discussions in the MOLAN meetings. I thank Gerard for the discussions we had on the iron projects, and also to start his work on the wonderful iron MeN3Py complex; I hope that you will find that the complex was put to good use in this thesis.

I thank Prof. Marcel Swart for the training, advice and help on DFT calculations, and also the many discussions we had during conferences and COST action meetings; Prof. John McGarvey for the discussions on Raman spectroscopy and iron complexes, and to be present on my PhD opposition panel; Prof. Miquel Costas for the many discussions we had and also your hosting me in Girona; Prof. Christine McKenzie for our collaboration on the manganese project, and taking part in my PhD opposition panel and finally Dr Anna Company for the many skype meetings on various projects and for your hospitality in Girona.

I thank Dr. Hans de Boer, and Dr. Ronald Hage (CATEXEL) for the discussions on all

chapters in my thesis and much more, I had really great time to learn from both of you; always our meetings generated with tons of suggestions, and thanks also for the TMTACN, and DTNE ligand.

Dear Sai and Tjalling, thank you for accepting the task to be my paranymphs. Tjalling, I am very happy to share our office with you and the fun moments and the discussions we had both in office and coffee breaks, and especially for your constant motivation to go for coffee and lunch breaks at normal times.

I thank all the Brownie group members who have helped me lot during my PhD. Duenpen, thank you for the help you have provided through out PhD, especially your discussions and the synthesis of many of the ligands I used. Juan, thank you for your help

and discussions on iron projects, and also the enthusiasm you have shown to become a real chemist. Gloria, it was great having you here in Groningen, thank you for help on the nickel project and for the social life outside the lab. Luuk, I really enjoyed our discussions, the board games and especially thank you for the minions you have given me, they are of great inspiration to me.
