WebJul 26, 2024 · Iron(II) (3d 6)-based spin-crossover (SCO) materials are the most intensively studied [9,10,11,12,13,14], because magnetic and chromic changes would be drastic between the low-spin (LS) S = 0 diamagnetic and high-spin (HS) S = 2 paramagnetic states. Furthermore, much attention has been paid to SCO near room temperature required for … WebThe high spin complex is the compound with the greatest number of unpaired electrons. There are fewer unpaired electrons in the low spin complex. Low spin complexes have high crystal field splitting energy. In the Cr NH 3 6 3 + complex, the center metal atom chromium Cr is in + 3 oxidation state. Only three of the five 3 d orbitals are filled ...

WebJan 15, 1996 · A study of high- and low-spin cobalt (II) derivatives having hexadentate encapsulated ligands known as ‘sar’ is reported (sar = 3,6,10,13,16,19-hexaazabicyclo (6.6.6)icosane). The chemically prepared derivatives have well defined EPR spectra at 4 K especially in the g = 9 region, and were clearly high-spin Co (II). WebIron(III) porphyrazines containing peripheral 2,5-dimethyl-, 2-methyl-5-phenyl-, and 2,3,5-triphenyl-1H-pyrrol-1-yl substituents were synthesized and subjected to physicochemical characterization.
