A bis(radical) derivative based on a triphenylphosphane core substituted by two nitronyl nitroxide units is reported. This compound was isolated in two forms. One consists of an H2O adduct where H2O is hydrogen-bonded to the radical units, whereas the second lacks this bridging unit. Magnetic studies revealed that the presence of the H2O bridge induces ferromagnetic exchange interaction between the
报道了基于被两个硝酰基氮氧化合物单元取代的三苯基膦核的双(自由基)衍生物。该化合物以两种形式分离。一种由 H2O 加合物组成,其中 H2O 与自由基单元形成氢键,而第二种则没有这种桥接单元。磁性研究表明,H2O 桥的存在会引起自旋载流子之间的铁磁交换相互作用。(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2003)
