Phosphorus mononitride (PN) and arsenic mononitride (AsN) species supported by two different N‐heterocyclic carbenes were prepared: The reaction of [(IDipp)NSiMe 3 ] [IDipp = 1,3‐bis(2,6‐diisopropylphenyl)imidazolin‐2‐ylidene] with PCl 3 or AsCl 3 afforded the dichlorides [(IDipp)NECl 2 ] (E = P, As) and, after the addition of IMes [IMes = 1,3‐bis(2,4,6‐trimethylphenyl)imidazolin‐2‐ylidene], the cationic chloro species [(IDipp)NE(Cl)(IMes)]Cl (E = P, As), which were reduced with potassium graphite (KC 8 ) to yield the neutral compounds [(IMes)PN(IDipp)] and [(IMes)AsN(IDipp)], which exhibit the typical trans ‐bent geometry of dicarbene‐dielement species in the solid state according to single‐crystal X‐ray diffraction.
