The preparation and reactivity of a range of novel paramagnetic chromium­(II) complexes supported by a carbazole-based PNP pincer ligand is reported. Deprotonation of the ligand precursors R(PNP)­H (1 R ) and subsequent reaction with chromium­(II) chloride led to the formation of square-planar chlorido complexes R(PNP)­CrCl (2 R ). Further reaction with various alkylating agents resulted in the isolation of chromium alkyl complexes R(PNP)­CrR′ (3 R -R′) which were then hydrogenated to yield two rare examples of paramagnetic chromium­(II) hydrides 4 i Pr and 4 t Bu . Both compounds were characterized by X-ray diffraction and paramagnetic NMR spectroscopy supported by a comprehensive DFT-supported assignment of the resonances. While the di­(tert-butyl)­phosphino PNP substituted complex 4 t Bu was found to exhibit a monomeric square-planar molecular structure, its isopropyl-substituted analog 4 i Pr forms a dimer, also indicated by a strong antiferromagnetic coupling of the chromium centers. The pronounced reactivity of these compounds toward CX double bonds was demonstrated by reaction with benzophenone, N,N′-dicyclohexylcarbodiimide, and carbon dioxide, which gave the corresponding insertion products. The alkoxido complex 5 i Pr , the amidinato complex 6 i Pr , and the formato compound 7 t Bu were also characterized by X-ray diffraction.
