Magnetically bistable Co(II) and Fe(II) complexes featuring pentyl-decorated pyridyl-benzimidazole ligands: role of isomerism and chirality Three variants of 2-(pyridine-2-yl)-1H-benzimidazole bidentate ligands, with distinct pentyl substituents (n-pentyl (L1), (2S)-2-methylbutyl (L2S), and (2R)-2-methylbutyl (L2R)), were synthesized and ...

I am glad that we could contribute to this interesting project led by prof. Ivan Salitros on magnetically bistable Co(ii) and Fe(ii) complexes published in Inorganic Chemistry Frontiers

I played the Leningrad variation of the Dutch defense.

I always love returning to Switzerland. This time to attend #EuCOMC2025 in Bern and speak about mechanochemical cross-couplings.

Cordial congratulations to our PhD student Zuzana Mravíková for receiving Dean´s award for the best publication of PhD students for her work published in ChemSusChem 2025, 18, e202402599 (lnkd.in/eWDu5ppB)

I cordially welcome our new postdoc, Dr. Suman Yadav, have a good time in research group.

Yes, arrows are a fascinating topic 😃
