Angewandte Chemie, EarlyView.New aza‐diphosphinanes have been prepared and a model has been developed to explain their cis/trans isomerization. Two‐fold oxidation leads to new aza‐diphosphazenanes as robust inorganic connectors with selectable stereochemistry. Polycondensation reactions results in the first inorganic cyclo‐linear polyphosphazenes which have high‐molecular weights ...
