Our calculations correctly reproduce the experimentally reported data and allow us to gain further and systematic insight on how to tune up or down the T1/2 value. The axial thiocyanate ligand can be replaced by similar groups (NCO−, NCSe− and NCBH3−) that allows for a large change in the T1/2 value, while a much finer degree of tuning can be achieved by functionalizing the para position of the pyridine groups. Altogether, [Fe(OEt-L1-pH)(NCS)3]− offers a unique platform to explore how ligand design can be realized to prepare new anionic SCO materials with tailored properties.9 p.application/pdfeng(c) Royal Society of Chemistry, 2022LligandsComplexos metàl·licsEstructura electrònicaLigandsMetal complexesElectronic structureinfo:eu-repo/semantics/article7304102023-05-05info:eu-repo/semantics/openAccess
