Popis:	Bis(trifluoromethyl)arsinous azide (CF3)2AsN3 undergoes a Staudinger reaction with PPh3 to give the arsinophosphazene (CF3)2As–NPPh3 which reacts with [Os3(CO)11(MeCN)] and [Os3(µ-H)2(CO)10] to give [Os3(CO)11{(CF3)2AsNPPh3}]1 and [Os3(µ-H)2(CO)9{(CF3)2AsNPPh3}]2 respectively. Single-crystal X-ray structural studies show that upon complexation (CF3)2As–NPPh3 assumes a highly delocalized electronic structure over the unsymmetrical As–NP segment with the As–N bond distance assuming that of an AsN double bond. These two complexes represent the first examples of neutral compounds containing a highly delocalized AsNP non-linear structure.
