Ambient-Temperature Spin-State Switching Achieved by Protonation of the Amino Group in [Fe(H2Bpz2)2(bipy-NH2)]

Ambient-Temperature Spin-State Switching Achieved by Protonation of the Amino Group in [Fe(H2Bpz2)2(bipy-NH2)]

Magnetism of a complex [Fe­(H2Bpz2)2(bipy-NH2)] (H2Bpz2 = dihydrobis­(1-pyrazolyl)­borate, bipy-NH2 = 4,4′-diamino-2,2′-bipyridine) has been altered from paramagnetic to spin-crossover (SCO) behavior, through protonation of one amino group of bipy-NH2 with CF3SO3H. Complete SCO transition, both in s...

Zusammenfassung:Magnetism of a complex [Fe­(H2Bpz2)2(bipy-NH2)] (H2Bpz2 = dihydrobis­(1-pyrazolyl)­borate, bipy-NH2 = 4,4′-diamino-2,2′-bipyridine) has been altered from paramagnetic to spin-crossover (SCO) behavior, through protonation of one amino group of bipy-NH2 with CF3SO3H. Complete SCO transition, both in solid state and in solution, occurs at ambient temperature.
