Abstract

original image

Vergleich mit dem Radikal: Das neutrale Tris(N-phenothiazinyl)boran 1 und sein Radikalkation 1.+ wurden synthetisiert und bezüglich ihrer Molekülstrukturen und spektroskopischen Eigenschaften untersucht. Der Radikalkation-Charakter von 1.+ ist demnach auf einem der Phenothiazin(PTZ)-Ringe lokalisiert. Kristallstrukturanalysen von 1.+ zeigen eine Aufweitung der B-N-Bindung zum PTZ.+-Ring (B-N1: 1.53 Å).
