N2 - Iron(III) Schiff base compound [Fe(pap)2]ClO4·H2O (1, and Hpap = (2-(2-pyridylmethyleneamino)phenol)) shows abrupt spin crossover (SCO) with a hysteresis (T1/2↓ = 165 K, T1/2↑ = 180 K) and anomalous light induced excited spin state trapping. In the complex 1, the existence of the interaction between molecules by π electrons is suggested from single crystal structure. An anomalous LS → HS conversion, aberrant increase of HS molar fraction, was observed at low-temperature (50 K) in 1 after rapid cooling, and interpreted in terms of bistability resulted from strong cooperative interactions.
