Owing to the peculiar electronic and steric properties of this ligand, the first neutral stable Ni(ii)-hydride, and an unusual Cu(ii) complex displaying a seesaw geometry, have been isolated.en© The Royal Society of Chemistry 2014Isolation of a potassiumStabilizing pincer ligandTransition metal complexesPotassium compoundsLigand field theoryLigands (Biochemistry)Transition metalsIsolation of a potassium bis(1,2,3-triazol-5-ylidene)carbazolide : a stabilizing pincer ligand for reactive late transition metal complexesPostprint Article
