Besides the conventional diamagnetic redn. products, persistent radical complexes formed as escape products that could be fully characterized by ESR. The paramagnetic species obtained from the bridging systems I-IV are binuclear radical anion complexes [L(AlH3)2]-· (L = I=IV), whereas the chelating bpy radical anion coordinates with one AlH2+ ion from the Al hydride dissocn. equil. A hyperconjugative model (\textgreek{p}N/\textgreek{s}Al-H) is used to relate the Al hydride coupling consts. with the coordination geometry in the radical formation.
