Pyridyl-Substituted Thioaminyl Stable Free Radicals: Isolation, ESR Spectra, and Magnetic Characterization1
摘要:
N-[(4-Nitrophenyl)thio]- (1a) and N-[(2,4-dichlorophenyl)thio]-2,6-diphenenyl-4-(3-pyridyl)phenyl aminyl (1b), N-[(4-nitrophenyl)thio] - (2a) and N-[(2,4-dichlorophenyl)thio]-4-phenyl-2,6-di(3-pyridyl)-phenylaminyl (2b), and N-[(2,4-dichlorophenyl)thio]-2,6-diphenyl(4-pyridyl)aminyl (3) were generated by PbO2 oxidation of the corresponding precursors. Although 3 was not sufficiently stable to be isolated, both 1 and 2 persisted in solution without decomposition and could be isolated as radical crystals. X-ray crystallographic analysis of 1b revealed that the Ar-N-S-Ar' pi-framework is approximately planar and the 2- and B-phenyl groups are significantly twisted from this plane. The magnetic susceptibility measurements for the isolated radical crystals were carried out using a SQUID magnetometer in the temperature range 1.8-300 K. The susceptibilities of 1a and 2a were explained in terms of a one-dimensional (1D) antiferromagnetic (AFM) regular Heisenberg model with an exchange interaction of 2J/k(B) = -63.4 and -17.8 K, respectively, and that of 1b was interpreted in terms of a 1D AFM alternating Heisenberg model with 2J/k(B) = -12.8 K and a (alternation parameter) = 0.91. On the other hand, that of 2b was explained in terms of a 1D ferromagnetic regular Heisenberg model with 2J/k(B) = 22.4 K.
