Temperature dependency of the magnetic properties was investigated by measuring T vs. T in the temperature range of 300 -2 K. The measured T value at 300 K was 3.9 cm 3 mol -1 K (S = 2, g  2.28) confirming the HS state of Fe(II) in 5. Upon cooling down, the T value decreases gradually to attain a plateau of 0.45 cm 3 mol -1 K below ca. 70 K, suggesting a gradual SCO with a T1/2 value of 114 K. The photomagnetic studies under green laser (532 nm) irradiation for ca.
