摘要：

A value of 2.71 μB for the effective magnetic moment between 100 and 300 K is determined for 1. This magnetic moment supports the assumption of a triplet ground state for 1. The bis(nitroxyl) diradical, which melts only at 180 °C with decomposition, could be characterized by X‐ray crystallography. It has a distinctly more planar conformation than the analogous monoradicals. (Figure Presented.) Copyright © 1995 by VCH Verlagsgesellschaft mbH, Germany
